Construction of a motorized towing vehicle (motorized dog): inside and out

Hi all! In this article I will talk about the main stages of building a homemade motorized towing vehicle on a standard Buranovsk track, 380 mm wide, with a Lifan engine with 8 hp. So, straight to the point:

Assembly video:

First of all, you need to weld the base of the frame, which is a simple rectangle, from 20x40 mm profile pipes.

Next, we prepare and weld the steering wheel mounting posts from the same profile, but with a larger wall thickness, in our case 2 mm.

The next step is to start making the steering wheel from a 20×20 mm profile and a round pipe with a diameter of about 22 mm. We further strengthen the place where the steering wheel is attached to the frame by welding washers, because this node experiences quite high loads.

After this, he begins to manufacture the drive shaft mounts from an iron sheet, 3 mm thick.

Now we return to the base of the frame. For engine mounting and general rigidity, it is necessary to supplement it with transverse sections from the same profile.

Next, we weld the drive shaft mounts flush to the front of the frame.

Then we proceed to the manufacture of the engine protective frame. In our case, a homemade pipe bender was used for this, but you can do without it by simply welding the pipes into a structure of the desired shape.

Next, we make the engine mount from a 40x4 mm corner. We cut 8 pieces of equal length and weld them into the front of the frame.

The next step is preparing the fastenings for the suspension bogies of the motorized towing vehicle, which are sections cut from a 40×4 mm steel strip with drilled holes. And immediately weld them.

Now that the frame is almost ready, we weld the previously prepared engine protective frame and the sections connecting this frame with the steering wheel mounting posts.

The frame is ready, we clean the welds and sharp edges, and prepare the structure for painting.

After the paint has completely dried, we fasten the pre-cut galvanized sheet using rivets, and then cut out holes for the engine mounting bolts.

The design is ready, you can begin final assembly. First, we install the track with the drive and driven shafts. Then 3 suspension rollers, a mudguard, a driven sprocket and, finally, an engine with a drive sprocket and chain.

Let's move on to preliminary tests. It is clear that without snow it will not be possible to fully test the structure, but I don’t see any particular need for this. Now I will explain why.

In general terms, this design repeats our previous motorized towing vehicle, created at the end of last fall and which has proven itself well over several months of operation. All of its shortcomings and weak points were eliminated in the new design, which is also quite primitive in itself and there is nothing special to break there.

We collect components

The second point is the components.
It’s one thing when the manufacturer does something himself and the manufacturer’s power is enough to turn the sprocket and make the shafts yourself, but you need to buy it in the store and you buy the spare part at a premium from the manufacturer, who created it and gave it to the store for his own margin . The store, in turn, also wants to make money, and you buy components for the towing vehicle with a markup of approximately +100 percent of the cost. The engine, transmission, variator belt, chains, bogies - all this costs money. Assembling the carts yourself is expensive. The manufacturer buys the caterpillar for 6,000 rubles, and they will sell it to you for ten.

The maximum you can save on when assembling a motorized towing vehicle with your own hands is in metal. You can save on the frame. But what you saved on the frame, you will spend it all on buying spare parts, buying tools, plus you need to set up the whole thing so that everything works.

Homemade motorized dog

A homemade motorized towing vehicle, made from scrap materials, has a reduced operating cost and more powerful technical characteristics compared to similar purchased models.

Successfully making a motorized dog with your own hands involves several stages at once. Among them:

1. Selection of basic structural elements with the necessary parameters.
2. Studying drawings, diagrams and video instructions, which allows you to avoid errors during assembly.
3. Direct manufacturing followed by testing.

This allows you to make the necessary changes to the design and achieve the desired operating parameters, for example, lower fuel consumption or increased speed. If desired, you can implement additional compartments for various useful tools, gear and other types of equipment.

Manufacturing of basic structural elements

There are several elements that need to be prepared in advance for successful self-assembly of such a mechanism. This is a power unit that has enough power to perform this kind of task. For this purpose, gasoline-type engines equipped with 1 cylinder are used.

Other elements worthy of mention are:

• caterpillar mechanism;
• suspension;
• motorized towing vehicle frame;
• transmission.

Each of these nodes requires careful attention, and therefore it is advisable to study them in more detail. Models from Japanese manufacturers, for example, Yamaha or Honda, as well as budget Chinese analogues, are widely used as engines. In this case, the use of motors from walk-behind tractors, chainsaws and other improvised devices is allowed.

The selection of suitable tracks should also be given due attention, since they are not only specialized, but also universal, designed for snowmobiles and other equipment. It is believed that the best option would be tracks at least 50 cm wide, since they will make the device stable and maneuverable

When planning to implement a transmission, it is necessary to note the possibility of choosing between mechanical, automatic gearbox and variable. Despite the accelerated wear of parts, automatic transmission is considered preferable because it can significantly increase traction force. As a budget option, it is possible to use a gearbox, for example, from a VAZ.

Its reliability directly depends on the strength of the unit’s frame, and therefore it is advisable to make it yourself, using a welding machine. For this purpose, pipes of at least 3 mm thickness are suitable, which avoids deformation under heavy loads.

If you want to make a motorized dog from Buran or other mechanisms, you will need:

1. Install the engine onto the frame.
2. Install the chassis, making the front and rear axles.
3. Connect it to the gearbox.
4. Install tracks and controls.

The suspension of the device can be roller or slip, depending on the season of intended use. The first option is suitable for use in summer, autumn or spring, and the second - exclusively for the winter period.

Winter motorized towing vehicle

Guided by diagrams, drawings and video instructions, it is enough to assemble a structure from pre-selected elements, which will allow you to quickly produce a motorized dog. For a winter motorized towing vehicle, it is advisable to use a ski module for the driver’s platform, as well as a roller type of suspension. Otherwise the design is completely identical to the standard one.

How to do it yourself?

In this part of the article we will look at how to make a homemade ski module.

Tools and materials

Materials can be purchased at the store or taken from old unnecessary equipment:

• profile pipe;
• saddle;
• plastic skis;
• steering wheel;
• shock absorbers.

• welding machine;
• Bulgarian;
• drill;
• spanners;
• small consumables (fasteners).

Manufacturing scheme

The main part of the ski module design is the frame-frame; it is recommended to start assembly with it, in accordance with the previously selected drawing. The main design feature is the distance between the skis (about 90 cm).

The motorized towing vehicle control system will be transferred to the steering wheel of the future module. The last step is to attach the seat and spring skis.

What is a motorized towing vehicle - description and purpose

A motorized dog is understood to mean a mini snowmobile (mini-all-terrain vehicle) with an engine. This vehicle is a coupling of a caterpillar towing vehicle with a sleigh or drag sleigh. The driver of the motorized dog sits in the sleigh, and any cargo is placed there. Some dog models have a special cargo area on the tractor. Engine power is usually from 6 liters. With. up to 13 l. s., speed is 30-40 km/h. The motorized dog does not have a brake, which the driver must always remember.

Motorized towing vehicles are popular among fishermen and hunters. They can also be used in agriculture and forestry for transporting small loads. Unlike wheeled vehicles, skis on a motorized dog sled allow you to move even on loose snow and winter off-road conditions, which makes the vehicle resemble a snowmobile. The only difference is the driver’s position: he sits outside the platform with the motor, which reduces the weight of the motorized dog and increases cross-country ability. Also advantages in comparison with a snowmobile are the simplicity of the design and lower price.

You can use motorized dogs to move along the frozen surface of a body of water - a lake, a river. They are ideal for ice fishing enthusiasts and have been designed specifically for them. The machine can be easily transported in a car using a cover, unloaded on shore, and then used for its intended purpose. On a motorized dog it is possible to transport cargo over rough terrain, replete with descents and ascents. They use the equipment for traveling in summer, spring, and autumn along swampy meadows and forest paths.

Why is it worth making a motorized dog - reasons

Both purchased equipment and homemade equipment are unpretentious, compact, and do not require much space for transportation and storage. But some hunters prefer to make motorized dogs themselves, using improvised means. The main reason is cost-effectiveness: a homemade version will cost an order of magnitude cheaper. For no more than the cost of the simplest towing vehicle from China, you can also build a reliable, durable pusher towing vehicle.

With a front-mounted motorized dog engine, which is almost always planned in home-made models, the operation of the machine will be much more efficient. Here are the obvious advantages:

• fuel savings and overall reduction in design costs;
• higher driving speed;
• the ability to make additional compartments for gear.

What to look for when choosing

Suspension

The greatest load during off-road driving falls on this element. The suspension distributes the weight of the equipment and cargo onto the track, while the force can change dramatically. The suspension is:

• roller (this type is considered to be all-season) - the tracks move on rotating rollers: not suitable for driving on melted or loose snow;
• slick - an ideal option for moving on snow, since the design features involve the sliding of the caterpillar track along the slicks (skis), in addition, heating occurs due to friction, and the main components cool under the influence of snow;

Important! Vehicles with this type of suspension stand out from the rest due to their excellent cross-country ability and economical fuel consumption, however, it is not recommended to operate such motorized towing vehicles without snow. Certain types of equipment are equipped with springs for better comfort during movement.

pneumatic - made specifically to overcome swampy terrain (units with such a suspension are characterized by a smooth ride, which makes the ride as comfortable as possible).

Motor

The latest generation of motorized towing vehicles, as a rule, have 4-stroke gasoline engines with a power of 5-15 horsepower. Honda (Japan) and Briggs&Stratton (USA) have proven themselves to be excellent. Their worthy rivals are Lifan and MTR from China. Experts advise giving preference to high-power models, because only such a motorized dog can cope with the most difficult tasks.

Transmission

For ease of controllability, manufacturers equip their units with an automatic clutch or a CVT. The most favorable solution, according to experts and buyers, is a transmission with a Safari variator, which has proven itself excellent in the harsh Russian climate.

Application area

The equipment is selected taking into account the specifics of the territory, the cargo that is planned to be transported, as well as the type of road surface. For fans of winter fishing and hunters, a small-sized device that perfectly overcomes ice and snow would be an excellent option.

To operate motorized dogs in the fall and spring, experts advise taking a closer look at units that are capable of crossing swampy terrain.

Helpful information! Motorized towing vehicles with roller suspension ride well on grass and mud.

Load capacity

To have a pleasant time outdoors with friends, you should focus your attention on the traction capabilities of a particular model. If the user loves speed, then it is worth giving preference to lightweight and high-speed equipment

A sled's carrying capacity of about 200 kg is enough for one fisherman, and if a group of several people gathers to hunt, then it is worth purchasing a model that can handle 500-700 kg of cargo in a hitch.

Manufacturer

The final criterion is the manufacturer, since the Internet presents a large number of primitive equipment assembled by amateurs.

Factory models

After the rapidly increasing demand for a motorized dog pusher, such units began to be manufactured in Russia. The designers were able to develop options with a small engine that fit perfectly with the two-track attachment. Each track is equipped with special holes. Classic models boast the presence of two plastic sprockets on the axle, where the tracks are mounted. This technical approach is more practical, since specialists managed to extend the service life of the motorized dog.

The disadvantages include the low power of the engine, which is designed for only seven liters. The final acceleration will not exceed 20 km/h. Of course, it will be difficult for such a technique to cope with two drags at once, since it belongs to the category of lightweight mechanisms

To choose the right caterpillar for a motorized dog, you need to pay attention to the power of the products

Motorized towing vehicle - how they make it at the factory from A to Z

The designer drew the whole thing, measured every hole, every bolt, and attached everything. The assemblers are competent, professional, and assembled. The CMK shop welded the whole thing, painted it, did everything beautifully - appearance, design. They sold it to you and gave you a year of warranty, someone else gave it 2 years of warranty.

You drive, don’t worry. Something rustled, you dragged it to the dealer and said: Guys, fix it. Everything was done for you under warranty, and you can continue riding. And you no longer worry that you need to go to the garage, cut up this towing vehicle, and reassemble it, because something is wrong, something doesn’t work.

Anyone steps on their rake, even a professional welder. He cannot be a professional welder, he cannot be a mechanic, a person cannot absorb everything perfectly. Every person has mistakes, and he will make them in any profession.

Therefore, you can spend time, so to speak, when you assemble the towing vehicle yourself, there will certainly be savings. You will save some money, because the manufacturer has collected and needs to earn money, he needs to pay wages, rent, etc. He appraised it, gave it to the dealer, and the dealer appraised it. Well, how much will you save? Dealer delta. You won’t be able to beat the factory price, because the plant has its own capacity, components, which it produces 70 percent of itself, rather than buying from someone else, so it’s easier for him. He already has it set up on a conveyor belt and goes in a chain.

He collects from 30 to a hundred a day, and people understand how to do it. The more you collect, the lower the cost. You take a kilogram of metal for 200 rubles, and if you take a ton, then the cost will already be 120 rubles. That is, the manufacturer will always be cheaper.

When you want to drink coffee, you don’t invent a coffee maker. You just go and buy it, because you know that it has been thought through to the smallest detail and that it will grind your coffee and make a really delicious cappuccino. If you start collecting it yourself, you will first get poisoned, then something will go wrong with you. That's true anyway. Having saved 10 thousand, you will spend a lot of nerves, time, money again. It's not worth it.

Replacing the top sprocket on the driven shaft

For those raiders who have already traveled, for experienced riders on motorized towing vehicles, who move along a reservoir or along a well-worn road, speed is partly important, because you can accelerate and get there faster.

It’s possible to make such a motorized towing vehicle. Put the 30th belt and the 11th (11 teeth) top sprocket on the driven shaft, and your speed will increase if the transmission is set up correctly and the engine is running correctly at the right speed. In general, the towing vehicle can accelerate with a 15 horsepower engine, with a 30 belt and 11 top sprockets on the drive shaft and a 26 on the driven shaft - it will accelerate from 40 to 50 km per hour.

If this is not enough for you and you still decide to tune your motorized towing vehicle and make it as fast as possible, what should you do? If you have a classic transmission from a Buran snowmobile - this is a Safari variator with movable and stationary transmission discs, what should you do? The driven disk is removed, 4 mm washers are placed there so that the 33rd belt fits there perfectly. It all comes back together - the driven transmission. It turns out that the gap between the slave and master disks has become larger and increased. Accordingly, the variator itself is designed for 33 belts from the very beginning, there is no need to adjust anything there. And that's it - put on the 33rd belt.

To be even more sure that it will start watering at all, you need to replace the standard 11-teeth upper sprocket on the drive shaft with 13 teeth, and accordingly the speed will increase.

And your towing vehicle, with proper tuning and good components, will probably accelerate to 60 km per hour. But we must not forget that this is very dangerous, because a person, as a rule, does not have any means of protection - neither motorcycles nor snowmobiles - a sheepskin coat, a winter suit and that’s it.

And even at a speed of 30 km per hour, falling from a sled onto rolled snow is tantamount to hitting the asphalt. But if there are uneven spots or stumps, it’s unsafe. A person who understands will never do this, because with a standard belt, if everything is correctly configured at the factory, 40 km per hour is a good, decent speed.

Moreover, if you set your motorized towing vehicle to 60 km, where can you drive at that speed? The motorized towing vehicle is designed for driving in snowy areas, where walking on foot is inconvenient due to the great depth, and skiing takes a long time and you get tired. On virgin soil, on snow, a motorized towing vehicle will not run 60 km per hour, the speed is still lost.

Recommendations

Some tips on how to properly carry out maintenance to extend the life of your motorized towing vehicle, from professionals.

Track Maintenance

In order for the caterpillar belt to work for a long time, you should adhere to a number of basic recommendations.

Before you start operating (once a day), inspect the condition of the chassis: “stiff” rollers or loose bolts can become a source of caterpillar failure. After a break in operation, it is necessary to clean the track and elements of the suspension system from the ice crust.

Over time, the track stretches and needs to be tightened.

You can check the tension by measuring the sag of the track. A sag of 2 to 5 centimeters can be considered standard.

It is worse to tighten the track too much than to loosen it too much, since this leads to stretching of the element and breakage of the driven and driven axle bearings.

If the caterpillar has stopped making revolutions, this indicates a breakdown of the chassis. The main factor in its braking is the malfunction of the shaft supports or bogie rollers due to moisture penetration inside.

You need to regularly inspect the condition of the chassis by rolling the motorized dog with your hands. It should also be easy to ride by hand with the chain and belt removed. Once every 12 months or every 40 hours of operation, maintenance of the undercarriage of motorized dogs should be carried out.

Motor Maintenance

The key rules are easy to learn. The first thing that needs to be monitored, in addition to refueling, is the oil level. To do this, unscrew the plug and look at the dipstick. Add oil to the required level. We change the oil every 5 tanks of fuel used.

A common problem is the air filter becoming clogged with tiny snow particles or the appearance of an ice crust. Signs: unstable operation, smoking, difficult to start. Dry the filter or install a new one.

Chain tension

The dog chain communicates rotational movements from the drive sprocket to the sprocket connected to the driven link; it should not be too tense, since the load on the bearings of the driven part of the CVT gearbox increases, and it should not be allowed to sag. The chain is tensioned by raising/lowering the right lobe of the hub, the driven part of the CVT gearbox. Over time, the chain can stretch and should be tightened.

Transmission Maintenance

Protect the CVT gearbox and its mating part from dirt, monitor the cleanliness and integrity of the aluminum discs, chain and drive belt of the CVT gearbox, wipe with a cloth after completing each drive, and prevent oil from getting on the belt and discs. Lubricate the shaft and cheeks as needed. Excessive amounts of lubricants can cause problems.

After any trip, wash the chain with gasoline and lubricate or wipe the chain and profiled wheels. It is always advisable to take a backup circuit with you.

Keep an eye on the detachable connections, clean and let the motorized dog dry after any trip, store it horizontally in a dry, ventilated place, and your motorized towing vehicle will serve without breakdowns for many years.

How to make a motorized towing vehicle with your own hands, see below.

Types of motorized towing vehicles

All tracked towing vehicles are divided into 2 versions - front- and rear-wheel drive. Both types of drive have their supporters. Objectively, the difference is as follows.

The main advantage of rear-wheel drive motorcycles is maneuverability and controllability due to the fact that the center of gravity is shifted closer to the hitch point. They go great loaded. However, an empty motorized towing vehicle constantly rears up, capsizes on the rise, and simply buries itself in the snow.

In front-wheel drive motorized towing vehicles, the center of gravity is shifted to the front, which increases the contact patch of the track with the surface. The cross-country ability of such motorized towing vehicles is practically independent of the load, which generally provides better towing capacity and driving characteristics.

High loads on the stern of the towing vehicle lead to more frequent failure of drive parts. Most often, the springs of the balancer bogies burst, which immediately cuts the caterpillar in a circle. Even replacing the chassis bearings causes problems, which requires serious dismantling and adjustment work. It is necessary to remove the engine and adjust the lateral and longitudinal displacement of the variator, while repairing a front-wheel drive layout does not face such difficulties.

Thus, front-wheel drive dogs are more capable, require less maintenance, are easier to control and move faster.

Razgulay-18.5 comfort

Powerful, collapsible motorcycle dog with rear-wheel drive. Able to pass through even the most dense places, including icy reservoirs and viscous swamps. Uneven landscapes are smoothed out thanks to high-quality shock absorption. You also don’t have to worry about the track and bearings, because the engineers have thought out special protection for them.

The maximum permissible weight for transportation is 500 kg when attaching a drag net. The 18.5 horsepower Lifan engine, together with electric start, copes with such loads perfectly. The front of the body boasts a bright LED headlight, making driving at night a breeze.

Advantages:

• Economical fuel consumption;
• Rear drive;
• Good maneuverability;
• Easy to disassemble;
• Compact dimensions;
• Easy to find additional accessories.

Flaws:

No engine cover.

It was not without reason that the name “comfort” was added to the name. Users love the soft leather seat that comfortably seats two people. For this model, you can separately buy a windshield and a plastic case for the necessary small items.

How to choose?

The first thing you should pay attention to when choosing a motorized towing vehicle and its components is the dimensions. Compact models can be placed in a car, while standard-sized units are transported in a trailer. Goose and its cross-country ability

Goose and its cross-country ability

Considering the size, we should not forget that the larger the tracked transporter of a motorized towing vehicle, the better.

Engine and its power. The more people ride a motorized dog, the more horsepower the engine should have. It is worth remembering that Chinese manufacturers actually have “horses” that are not as powerful as those of the Americans. That is, the American engine is 13 liters. With. will work more productively than the Chinese 15 hp. With.

Workmanship. You must immediately carefully examine the accuracy and evenness of the seams, the uniformity of the coating of the parts.

Drive - front or rear. With rear-wheel drive, driving a loaded motorized towing vehicle is easier, since the center of gravity is located near the steering wheel, but an empty unit will rear up or bury itself in the snow instead of moving. In front-wheel drive vehicles, the track contact with the surface is better and maneuverability does not depend on the load.

CVT or gearbox, as well as suspension type.

Ease of system adjustment. Any motorized towing vehicle requires periodic inspection of structural components; an important criterion is the simplicity and convenience of these operations

When choosing, you should pay attention to the casing - it can be plastic and can be easily removed or made of a special material with fastening flaps

Accessories. Here you can do without restrictions, according to the principle “the more, the better” thanks to all kinds of modules, ski track builders, and wheeled carts. The motorized towing vehicle will become an indispensable assistant with many options for any time of year.

Man K2 - 18.5M

The “heart” of this axlebox is a 4-stroke engine with 15 horsepower. The unit is equipped with a 2-bearing transmission and a safari variator. A metal hood is used to protect the engine compartment. The frame material is durable 3mm steel. The drive shaft maintains a constant horizontal position thanks to self-aligning, serviceable bearings.

The length of the motorized dog is optimal for products of this kind and is 1450 mm. Track width – 500 mm. Thanks to the increased angle of attack, the pressure on the snow is reduced. This allows the motorized towing vehicle to pass through even 1.5-meter snowdrifts without problems.

Advantages:

• high level of load capacity – up to 0.75 t;
• thoughtful design (all units are reliably protected from external contamination);
• good lighting;
• increased angle of attack.

The disadvantage of the design is that it is somewhat prone to collapse.

Pomor 500 S15 (1450 mm)

The best option for multifunctional use. In addition to the standard functionality, the kit is rich in additional accessories: mounts for snowboards/skis, a removable rack, hand protection from the wind. The manufacturer did not focus on the design of the towing vehicle, devoting more effort to ergonomics and convenience. But this did not in any way affect the maneuverability of the vehicle.

The choice of roller or skid suspension smoothes out uneven terrain in wilderness areas, preventing rollovers. Deep snow is no problem for a motorized towing vehicle. The wide 50 cm double-sided caterpillar will prevent you from digging in or falling through.

Advantages:

• Heated handles;
• Storage case;
• High quality brakes;
• Navigation materials;
• Engine noise insulation;
• Develops a speed of 50 km/h.

Flaws:

Weight 120 kg.

When transporting large quantities of cargo, the steering wheel is adjusted to a vertical position. This allows the driver to drive while standing and have a better view of the road. For these purposes, users are advised to give preference to AI-95 gasoline.

Physical Features

When designing such a vehicle, you need to remember several important laws of physics, without knowledge of which your work will be reduced to zero. For good cross-country ability on a snowy surface, you need to make the contact area with the coating as large as possible. This will help the snowmobile not to fall through. In order to reduce the load on the snow cover, you need to make the weight of your vehicle as small as possible. In order for your snowmobile to be stable, another law of physics should be applied - you need to make at least three points of support. That is, a snowmobile with three skis will be more stable when moving than with two. The design may consist not only of skis, but, for example, of one track and two skis or, conversely, of a ski and a pair of tracks. There can be four support points, then you will get something resembling an ATV.

Most often, such units as “Dnepr”, “Izh” are used for such conversion; you can also find a “Ural” motorcycle on tracks. The steering part is left original; all the necessary systems are connected to it - clutch, gas lever. Steel pipes or angles are used for the frame. To make the ski, sheet steel and again angles are used.

Wheel modules for motorized towing vehicles

The principle of operation of a motorized towing vehicle, or, as they are also called, motorized dogs, and their traditional design suggest that the motorized team drags the rider behind it either in a drag sleigh, or on skis, or in a cart, but if the driver is placed on horseback on a mini-all-terrain vehicle, the towing vehicle will turn into already, rather, into a mini snowmobile or compact all-terrain vehicle. That is, if you sit astride a dog, then it is no longer a dog, but a deer or a horse. Some owners of motorized towing vehicles are already actively using wheel and ski modules, installing them on their motorized towing vehicle in summer and winter. The design of such modules significantly expands the scope and scope of year-round use of a traditional towing vehicle. The wheel or ski module is quickly and easily detached from the motorized dog and disassembled, which allows you to easily transport it in a car.

A ski or wheel module for a motorcycle towing vehicle is a metal frame with a pair of sprung skis or wheels, a motorcycle handlebar and a seat. All the necessary control levers of the towing vehicle are displayed on the steering wheel of the module. The frame is attached to the motorized dog platform using four bolts.

The manufacturer states that a motorized towing vehicle, for example, with a ski module creates a minimum specific pressure on the ground, which allows such a mini-snowmobile to more effectively overcome loose snow, and a towing vehicle with a wheeled module has greater maneuverability in wetlands and sand. Together with the module, any motorized towing vehicle weighs several times less than any snowmobile or ATV; moreover, a towing vehicle with a ski or wheeled module is much more compact.

Other types of machines

You can also assemble an ATV from a walk-behind tractor, although this unit does not develop ultra-high speed, but in terms of maneuverability and cross-country ability it is not inferior to its own. The landing position in a homemade ATV remains traditional, not a motorcycle one. Wheels can be used from any passenger car.

It is worth mentioning an interesting homemade product called karakat. The power of the car lies in its large wheels, which are ordinary inner tubes, tightened with strong belts.

They put homemade wheels on carakat, modifying standard car ones. A very original disk is also installed on a lightweight walk-behind tractor. To do this, two aluminum basins are connected along the contour, having previously cut the bottom to fit the size of the hub, stiffeners and side stops are installed to fix the camera.

Despite its external clumsiness, the caracat has high cross-country ability and stability. Not only can it easily overcome swampy lowlands, but it is capable of transporting significant cargo (up to 100 kg).

Criteria for choosing a motorized towing vehicle from experienced fishermen

Users who have been able to test a purchased motorized dog can provide useful recommendations. The tips below will help you approach the purchase of a car wisely:

• The most favorable power is considered to be 6.5 hp. This unit is suitable for transporting small loads, as well as several people. For driving through difficult terrain and transporting large loads, experts recommend buying a motorized towing vehicle with a power of 10 horsepower or more.
• Even before purchasing a machine, you need to determine what kind of drive is needed. Models with front-wheel drive differ from cars with rear-wheel drive in having better cross-country ability and, on the contrary, motorized towing vehicles with rear-wheel drive are faster than their “brothers”.
• Experts advise conducting a thorough inspection of the motorized dog to ensure that the main components are protected from corrosion. It would also be useful for the seller to consider the level of strength of the case.
• To drive at night, you need to buy a car with a powerful headlight.
• The heated grip option allows you to drive long distances.

Second life for old tires

There is another well-known method. Let's look at how to make a homemade motorcycle track using old tires. For such work, it is best to choose tires from large trucks. It is better that the tread pattern is kept in satisfactory condition. To work, we will need a very sharp shoe knife and some cutting skills, no matter how strange it may sound. In the manufacture of such a caterpillar, the method of cutting out the sides from tires is used. To ease the effort when cutting thick tires, you need to periodically dip the knife in a soapy solution. You can also use an electric jigsaw with fine teeth.

So, for old tires we remove the beads, select parts with a well-preserved tread pattern, or we will have to cut it ourselves to improve grip on the road surface. The undoubted advantage of such a tire chain is that it consists of a closed solid material, which means it is more resistant to breaks. The disadvantage of this design is the limited tire size.

Homemade snowmobile sled made from plastic pipes

Polypropylene or PVC pipes can serve as material for sleds. The design will be lightweight and suitable for any snowmobile. The connection of individual elements is carried out with a soldering iron. The load-carrying capacity of the structure will be small, since the plastic tubes will not withstand heavy loads.

Pipe blanks are cut to size according to the drawing

First you need a drawing. It's simple. The design consists of two curved runners that act as skis. Vertical posts extend from them, which support the main platform.

According to the dimensions of the snowmobile sled indicated on the drawing, blanks are cut from the pipe with your own hands. Prepare shaped elements for soldering. Heat up the soldering iron. From the shaped elements you will need tees and 90° angles. On skis you will need to bend the edges. This can be done by soldering 45° corners. However, the disadvantage of this method is that the soldered fitting has an edge with which the skis can cling to obstacles on the track. You can go another way. Avoid soldering the corners and bend the PVC tubes to the desired angle, after heating them with a hairdryer.

You can give the pipe the desired angle using a hair dryer, heating the area required for bending

After cutting the tubes, begin soldering. First, clean the edges of the workpieces. Nozzles are inserted into the soldering iron. Install the fitting and pipe section. When the plastic softens and begins to melt, the blanks are removed from the hot nozzle and joined together. All elements are collected in a similar way.

Advice! If you have no experience in soldering plastic pipes, it is best to practice on unnecessary scraps to avoid defects in the main structure. The fittings are joined to the pipe using a soldering iron.

The skis are assembled first. They consist of three paired pipes. Tees are soldered at equal intervals along the runners. Racks made of pieces of pipe are attached to the central outlet of the fitting. Their upper end is connected with jumpers using tees and pipes. They form the platform of the future sleigh.

Stands with jumpers are soldered to the runners from pieces of pipes and tees, forming a sleigh platform.

A rectangle is cut out of plywood according to the size of the platform contour. To make the seat soft, the blank is upholstered with an old blanket or foam rubber, and covered with leatherette on top. The platform is secured to the jumpers with overhead clamps or bolts through pre-drilled holes in the tubes.

Important! The plastic structure cannot be used to transport heavy loads. Lightweight homemade sleds for snowmobiles will be a joy for children and can support one adult

The best models from manufacturers

We will provide an overview of the most popular models of pushers that have found application in the snowy regions of our country.

For motorized towing vehicles "Koira"

This module comes complete with a sled and a bump stop, and is installed in the front of the towing vehicle. The driver is in a sitting position, which greatly alleviates the hardships of a long journey through snowy terrain, for example, to a hunting or fishing spot. The pusher increases the speed of travel, significantly compacting the snow underneath. The device is manufactured with a high level of quality: the frame, steering wheel and all components for control are made of thick profile pipe with a cross-section of 40x25 mm and a wall thickness of 2 mm. The steering part rotates smoothly and quietly thanks to rubber bushings.

Dimensions:

• length – 165 cm;
• width – 60 cm;
• height – 26 cm.

The dimensions at the extreme points of the bump stop are 160x82x46 cm. A 56 W halogen headlight is provided on the steering wheel. The soft transforming seat can be adjusted to suit the driver's height. On the steering wheel there is a gas trigger and a button for adjusting the lighting. For safety purposes, an emergency stop check is provided.

Pusher for motorized towing vehicle "Muzhik"

This version of the pusher is also mounted in front of the motorized towing vehicle, and also, like the previous one, allows the driver to move long distances in a sitting position. The trough of the device is made of high-strength plastic. The frame is welded from a profile measuring 20x40 mm and a wall thickness of 2 mm. The design dimensions are the same as those of the module for “Coira”: 165x60x20 cm. The drag sled with a bumper has the following dimensional parameters: length – 145, width – 60, height – 26 cm.

The model has a soft and moisture-resistant seat. There is a throttle lever and cable, and there is an 18 W LED headlight. There is an engine control on the steering wheel. The steering wheel grips have a comfortable rubber base.

Module for towing vehicle BTS

Weighs 25 kg and has the following assembled parameters:

• length-185 cm;
• width-78 cm;
• height-63 cm.

The set includes a drag sled, the length of which is 1.5 m. The design is equipped with a spacious, durable and moisture-resistant seat. The steering wheel has rubberized grips, a headlight for illumination and a throttle cable.

Tselina MB-509VB

Powerful and reliable engine Country: Russia (manufactured in China) Average price: 71,500 rubles.
Rating (2020): 4.2 The powerful motorized towing vehicle TSELINA MB-509VB takes a worthy place in the list of the best low-speed models of motorized dogs. The device is perfect for both household needs and for recreation and entertainment. One of the features of this model is that a drag sled is supplied with it. The weight of the motorized dog is 105 kg, which is relatively small. The total permissible load on the equipment is no more than 150 kg, including the driver. At the same time, the highest speed that the motorized towing vehicle will develop will be 20 km/h. The manual starting system will make starting the engine much easier, even in severe frosts.

The main advantages of using this model in customer reviews include convenient controls, a robust body and a reliable engine. A 4-stroke single-cylinder unit with a capacity of 9 liters is installed here. pp., which is powered by AI-92 or AI-95 gasoline. Maximum fuel consumption is 2.8 l/hour. A distinctive feature of this model is the presence of heated handles, which is especially important for winter use. The steering wheel folds, making storing equipment much more convenient. A strong LED headlight is installed at the front. Weaknesses include high cost and low carrying capacity.

When purchasing a motorized towing vehicle, we recommend paying attention to the following important characteristics:

Engine. The more powerful it is, the faster the motorized dog will move, and the larger the load can be placed on the drag sled. As a rule, single-cylinder four-stroke units with a power of up to 15 hp are installed. It should be remembered that greater engine power implies increased consumption and requires a larger fuel supply. Load capacity. Most motorized dogs have their own trunk, which is most often used to transport tools and an additional canister of fuel. In addition, the motorized towing vehicle is capable of pulling sleds with a load of 150 to 500 kg, depending on the design and engine power. Transmission. There are 2 types: automatic and CVT. The first type provides the greatest traction force, but is less reliable due to the large number of parts in the assembly. The CVT is somewhat more expensive than the automatic, but it lasts an order of magnitude longer. Track and chassis design. Here it is necessary to take into account the surface on which you plan to move on a motorized dog. For snow, devices with large hooks are better suited, but on hard ground they will only get in the way. In addition, some motorized towing vehicles can be equipped with replaceable ski and wheel modules. Frame. This is the main power element of a motorized towing vehicle.

It is necessary to pay attention to the profile of the frame and the thickness of the steel sheet from which it is made. Recommended thickness – at least 3 mm

This thickness will ensure that shock loads are received harmlessly for the overall structure and will not allow deformation. Fuel tank volume. It should be selected based on how voracious the motorized towing vehicle is. Optimally, it will be 2-2.5 hours of constant work. It should be remembered that carrying a large supply of fuel with you is not always convenient.

Exploitation

Before using the pusher, you must check all fastenings, the operation of the stop and gas levers, the functionality of the headlight, and the fastening of cables and wires. The pusher should be securely attached to the motorized towing vehicle.

After the first trip, check the tightness of all threaded connections, and after each use, clean the module from dirt, snow, ice, and lubricate the hinge joints with oil. If it is heavily soiled, it is necessary to wash the module. To wash, you must use detergent.

The pusher should be stored in a dry room with good ventilation or in a special small building. You can also leave it outdoors under a canopy, but so that it is not exposed to direct rays of the sun in the warm season.

Before turning on the engine of the motorized towing vehicle, you must make sure that the throttle lever of the pusher module has free movement and is not blocked. In addition, you need to apply the parking brake.

Changing the module design is strictly prohibited.

Its use is permitted exclusively for coupling to a motorized towing vehicle or sled in the front or rear. Not intended for use on sandy soils and water.

Comfort and safety

The more a manufacturer thinks about the ergonomics of the equipment they produce, the more convenient it will be for you to subsequently own and use it. These are the “little things” that you can do without, but which will ultimately determine how happy you will be with your purchase. The steering wheel should be folding. This simple idea has not yet been picked up by all manufacturers - but in vain: screwing or unscrewing the steering wheel in the cold is a very dubious pleasure (otherwise you won’t be able to load the motorized towing vehicle into a vehicle). The correct folding steering wheel, among other things, has a height lock. It will not fall under the driver’s feet, is adjusted to the driver’s height, and most importantly, it will be convenient to press on it in order to lift the front part of the track and quickly move over an obstacle. Gas handles and control unit. Here, manufacturers use different options, from cheap Chinese crafts to serious ATV designs. You will have to pay extra for quality, but the ride will be more pleasant and there will be fewer breakdowns. An electric starter is a nice thing, but by and large it is not very necessary. It’s a matter of taste and wallet: if you want to start a motorized towing vehicle with a button on the steering wheel, sitting comfortably in a sleigh, take an electric starter; ready to pull the manual starter and get into the sled a little later - you can save money. Reverse gearbox, or reverse gearbox. You can do without it, but it is a useful thing, especially if you drive through the forest and periodically climb into impenetrable windfalls. Turning a motorized dog around on a narrow spot is not an easy task; the included reverse gear will allow you to easily drive back along the already laid track. Ideally, the reverse gear is activated on the steering wheel, and not on the motorized towing vehicle itself. The safety check is a very important element; wear it every time you ride your motorcycle dog. An accidental stump under the snow, an awkward movement - and now you are already lying in the snow, and your motorcycle friend is cheerfully trotting away from you across the snow field at a speed of 30-40 km/h. The check is designed to prevent such situations: it breaks when the driver falls, which instantly stops the engine

Some manufacturers offer it as an additional option; In our opinion, every motorized towing vehicle should be equipped with this device, so pay attention to whether this part comes “stock”. Headlight, socket, electrical accessories. You can't drive in the dark without a headlight; Without a cigarette lighter socket you won’t be able to recharge your navigator away from home

On high-quality motorized dogs, an “electrical package” with a relay-voltage regulator, which allows the use of various electrical devices, is included immediately, as well as a headlight. The brake with parking mode is a very useful thing: you can safely warm up the motorized towing vehicle without fear that it will drive away from you across the field. Not available in all models and not all manufacturers, so please pay attention.

What are they?

You can turn a motorized tug into a vehicle that resembles a snowmobile using a ski-wheel module. With it, ease of use increases several times. The driver no longer sits on the sled, but in front of the motorized dog, and makes the steering wheel turns himself. The most convenient device for driving on snow; in summer it can be replaced with a similar wheel module.

The entire system weighs about 20 kilograms and also does not take up much space when transporting it. You can use a single-ski module or with two skis in front.

The advantages obtained by installing the steering module are an increase in the capacity of the drag sled:

• the driver no longer controls the vehicle from them;
• the speed of the motorized towing increases because the weight is distributed evenly;
• ease of control;
• also, due to proper load distribution, the contact of skis and tracks with the surface increases, and fuel consumption decreases;
• the stability of the system due to the wide arrangement of the skis, that is, the motorized towing vehicle will not tip over at an unexpected moment.

In addition to the advantages, there are also a number of disadvantages:

• you will have to obtain a driving license, since the new design is comparable to a mini snowmobile;
• it is difficult to drive through loose snow;
• frequent breakdowns due to heavy loads on the frame and chassis of the motorized dog.

The pusher module looks like a sled with metal runners and a plywood bottom. Its main function is to compact the snow in front of the tracks. The transforming pusher can be located both in front of the motorized towing vehicle and behind it.

Their name comes from an ancient design - “drag”. A regular sled moves through the snow with the help of two runners, while a drag sled does this with the help of a bottom. They can be divided into 2 subspecies - transport and fishing, the differences are only in size. In addition, special 8 mm thick pads can be attached to the bottom of the sled, which will protect the plastic from abrasion.

Popular brands

To develop and produce equipment with better cross-country ability and very powerful engines, you need considerable experience in mechanical engineering. The following companies have proven themselves to be the best:

• Lebedev Motors is a young company from Russia, since 2008 it has been producing all-terrain vehicles with one or two tracks;
• "Omela Group" - became famous thanks to the "Pomor" brand, produces motorized towing vehicles and equipment for them;
• “Baltmotors” is a Russian production company, closely cooperating with partners from China, their main goal is customer focus and affordable prices;
• “Paxus” - the all-terrain vehicles of this company are characterized by low fuel consumption, high maneuverability and ease of operation;
• “Irbis” - the company began its activities in 2001, now the main office is located in Moscow and has more than 2000 service centers throughout the country.

We buy metal and assemble the frame from scratch

Let's say you know how to use welding, what it should look like - you have an idea of ​​the technique, you understand it all. It's not that you're a techie with a higher education, but you understand technology. How it works, how it is structured, how to assemble it all. You see towbars in the store, at your friends' houses, and you realize that everyone assembles it a little differently. One has a single bearing transmission, some has a double bearing transmission.

Firstly. You buy metal for yourself at a metal depot and go to your garage. We will assume that you have a welder and all the tools, you have marked this thing and filed it. If you don’t have a tool, then you need to buy a welder, buy an angle grinder, and weld an even frame. It should look something like this. The photo shows a frame from a Tehmar motorized dog.

If you weld a crooked frame, then you will break the bearings on the drive shaft, there will be misalignment and, accordingly, there will be pressure on the bearing by the shaft.

The bearing will quickly fail, this will happen all the time, this is still a torment... Even some manufacturers suffer from this, they have crooked frames

Therefore, it is important to make an even frame, to give rigidity to the structure so that it does not move to the sides. This is a rather complicated process

It’s easy for a person who is at least somehow connected with welding, who cooked something at one time, to do this.

A person who sits at a computer all day long and works as a manager will not assemble a motorized towing vehicle in his garage. This is the first difficulty in assembling a motorized towing vehicle: you need a lot of tools and knowledge to help you in production.

How to make a ski module with your own hands

In order to make a ski module, you first need to understand its structure. To do this, you can view photographs or drawings of popular models on the Internet. As you will see, there is nothing complicated in its design. Therefore, if you have all the necessary parts, tools and skills, then it is better to make the module yourself. This will cost much less, and with the right approach the structure should be stronger.

As mentioned above, the ski module consists of a frame, saddle, a pair of skis, handlebars and shock absorption. You will need to weld the frame yourself, and the remaining parts can easily be obtained from the store. The principle of the steering wheel is the same as in a regular snowmobile: paired skis from below move together with the steering wheel. However, for a smooth ride, you need to install shock absorption of proper rigidity. Springs can be removed from an old Izh-Planet or another motorcycle or car.

The main thing to remember is the design features of the frame itself. The skis should be approximately 90 cm apart from each other - this will give the structure stability, and there should be places on the frame for attaching the module to the towing vehicle (usually four nuts).

This is how you can easily turn your motorized towing vehicle into a mini snowmobile. As we have seen, there is nothing difficult about this.

Cargo homemade sleds for snowmobiles

A special feature of cargo sleds is their resistance to heavy loads. This is achieved by using durable materials, such as metal. Skis are made wide. Due to this, the runners do not fall into the snow. Improves maneuverability and stability when the snowmobile moves at high speed. Shock absorbers are sometimes provided between the runners and the platform frame. They smooth out impacts on bumps. The sled bounces less, which reduces the likelihood of damage or loss of cargo.

Shock absorbers smooth out impacts when riding a snowmobile on uneven terrain, thereby improving cargo safety

The snowmobile sleds shown in the photo are made from metal with your own hands. The platform is covered with plywood. The sides are welded from tubes. They won't interfere with cargo sleds. It is convenient to secure the transported cargo with straps over the sides.

Mukhtar 15

Innovative 2022 model. The new product is positioned as a towing vehicle that can be used all year round in a variety of conditions, including complete off-road conditions. The motorized dog is equipped with a 15-horsepower Zongshen unit with a capacity of 420 cm3. A special feature of the model is wide 500 mm tracks. Thanks to the snow hooks, the structure moves through loose snow without any problems. The equipment set includes:

• rollers with seals made of rubberized material;
• towbar;
• Ruben belt 3.3x1.4x112 cm;
• roller-slide suspension;
• skis measuring 1010x150 mm;
• disc brakes;
• powerful LED headlight that allows you to move in the dark.

Such a rich supply set makes it possible to assemble different modifications of the axle box. The optional ski module turns the classic tug into a snowmobile. When equipped with wheels, you get an all-terrain vehicle with increased cross-country ability.

Advantages:

• versatility due to modular design;
• good level of traction;
• headlight included;
• reliable durable bearings.

The disadvantage is the high price. However, it is more than compensated for by its versatility.

Choice

When choosing a pusher, it is necessary to take into account that the width of the drag sled should be slightly larger than the width of the tracks of the motorized towing vehicle. The trough should be made of high-strength plastic - this material reduces the weight of the structure and will not create unnecessary load on the equipment.

The driver's seat should be soft and adjustable to suit the user's height. Riding in a hard and uncomfortable seat is very difficult and uncomfortable, especially over bumps. It will be good if the design of the pusher includes a headlight and protective glass. The frame must be painted with an anti-corrosion coating.

The pusher can be mounted both at the front and at the back. A pusher model with both of these options would be ideal, as the mount behind the tow can be used to carry additional cargo.

As for the height of the sides, they can be low or high. It is a mistaken belief that high sides provide better protection against snow getting inside the module. On the contrary, low sides are much more convenient, and snow does not fall into the trough, since it is already compacted by the front part of the device, which has a beveled appearance.

Purpose

A motorized pusher can significantly improve the maneuverability and controllability of a motorized towing vehicle in unsteady and deep snow, since the peculiarity of its design and the seated person create a large load on the surface of the snow, crushing the snowdrifts underneath. In this case, the layer of snow along the path of movement is compacted to the width of the towing vehicle's tracks, which facilitates its movement.

Thanks to this module, the performance characteristics of the motorized dog increase while climbing, and the weight of the driver sitting in it contributes to additional compaction of the snow mass, and subsequently to better adhesion of the machine’s tracks to its surface.

The turning angle is also greatly reduced, which increases the maneuverability and speed of the equipment. All the benefits of a pusher are usually felt during long-distance trips.

Of course, coupling to the module significantly increases the load on the towing vehicle frame, which reduces its durability. In summer, the pusher can only be used in swampy areas so as not to damage it.
