Motorized towing vehicle "Ruff" ? a compact dog, which is an intermediate step from a mini snowmobile to a motorized towing vehicle. This device is used for transporting people and various weights on snowy and icy paths on skis or sleds. From its analogues ?Ruff? differs in the principle of connection with drags. Other motorized towing vehicles are connected using an earring, but “Ruff?” ? through a rigid articulated coupling. This device is self-propelled, but you still have to operate it yourself? The driver's seat is located in the saddle on the body.
Motorcycle dogs ?Ruff? also used for recreation and winter racing in snowy areas, fields, forests? wherever there is a knurled track (this device is not very suitable for moving in deep snow). Such motorized towing vehicles are indispensable for fishing.
DIY mini snowmobile
Dear visitors to the “ Samodelkin Friend ” website, from the material presented you will learn how to independently assemble a snowmobile with an engine from a walk-behind tractor. Step-by-step assembly photos and a video of the mini-snowmobile running in are provided. Every avid fisherman and hunter knows perfectly well that in winter it is not very convenient to travel on loose snow on skis, and when it is necessary to cover a distance of several tens of kilometers to a farmstead, winter hut, hunting hut, or to a reservoir, then there is generally a “pipe)) For To cover long distances you need a snowmobile, but the prices of factory-made cars are beyond the means of the common man; again, repairs and spare parts will cost a pretty penny. So we do it ourselves, with our own hands))
To build the snowmobile, the author used an engine from a Lifan walk-behind tractor with a power of 9 l/s; this type of engine is very popular today among home-made people, wherever they are installed (tractors, all-terrain vehicles, boats, etc.). The internal combustion engine is located in the rear of the car directly above the track; by the way, it is made from half of the BURAN caterpillar cut in half.
The snowmobile runs quickly through the loose snow, carrying two people and runners with luggage, which once again proves that Kulibin’s business is alive and growing)

Payment (installments without overpayment)
Motorized towing vehicle Ruff is a miniature motorized dog that is a transitional link between a mini snowmobile and a motorized towing vehicle. It is designed to transport (move) people on sleighs (drags) or skis, as well as cargo along snow-covered paths in the forest, across fields, frozen rivers and lakes. Its fundamental difference from other motorized towing vehicles is that it is connected to the drag not through an earring, but using a rigid articulated hitch. The driver sits not on a sleigh, but in a saddle on a frame.
Ruff motorized towing vehicles are used not only for entertainment and winter cross-country racing, but also for practically useful tasks - transporting people and small loads on hard snow and ice cover, knurled tracks, etc. Unlike most motorized towing vehicles, it is not very well adapted to difficult surfaces such as loose deep snow or water. They have proven their usefulness in practice for fishermen and outdoor recreation enthusiasts.
Ruff is a vehicle measuring 90*55*75 cm and weighing only 50 kg - this is half the size of conventional motorized buses.
. Due to its light weight and compactness, it turns out to be weaker and less powerful, but nevertheless, maneuverability, exceptional ease of transportation and ease of movement on ice are invaluable advantages. It assembles and disassembles in just 2-3 minutes and easily fits in the trunk.
Ruff motorized towing vehicles are equipped with a 4-stroke 1-cylinder Subaru, Honda or Lifan engine with a power of about 6 hp.
, developing a fairly high speed of up to 25 km/h. Considering that fuel is consumed at 1.5 l/hour, the tank is enough for 40-60 km (depending on the complexity of the terrain and weather conditions).
Ruff motorized towing vehicles do not require registration
, are not subject to transport tax and even a teenager can drive them. There is no need to register them or obtain a special driver's license. They are more versatile and practical than a moped, more interesting and easier to drive than a snowmobile, and they don’t take up storage space. Motorized dogs Ruff have an attractive price, are wear-resistant, durable and can be repaired. In the event of a malfunction, they are easily loaded into a sled and taken to a garage or service center - even one person can easily handle this.
Repair of motorized dog "Ruff"
In order for your snowmobile to serve for a long time and without interruption, it is necessary to use it correctly, regularly clean and lubricate the main parts, as well as timely repair and replacement of worn-out components. All these procedures can be carried out either with your own hands or with the help of professionals. Remember that not only the condition of the equipment, but also the safety of passengers and the driver depends on the quality of this work.
If your car breaks down, you can call a tow truck or ask passing motorists for help. But in the event of a breakdown of the motorized towing vehicle “Ruff?” you will have to use your own hands. Therefore, we recommend that you study the design drawings of your snowmobile in detail and master basic repair skills for the most common breakdowns, so as not to find yourself in an unpleasant situation.
In such cases, the compactness and light weight of the device are especially appreciated. Thanks to these qualities, you can independently load it into the trunk or into a sled and take it to your garage or service center. Of course, it is better to repair such equipment in a special center, especially if the warranty is still valid. If it runs out, you can try to repair it yourself. But for this you need to have special skills, because the design of this snowmobile differs from other types of equipment (cars, motorcycles, etc.).
Motorized towing vehicle Ersh 2
Ruff 2 is a motorized towing vehicle for people who want a reliable vehicle at a minimal cost. The motorized dog does not know how to accelerate strongly, but it confidently copes with driving through loose deep snow, slippery ice, and small hillocks. The motorized dog is quite maneuverable, with a large turning radius, so it goes around trees and bushes with ease. It is noteworthy that the Ruff snowmobile has small dimensions; it can be unfolded and hidden in the trunk of a car. This undeniable advantage is appreciated by the owners - fishermen and hunters, who often transport towing vehicles in their cars.
The most common breakdowns of the motorized towing vehicle "Ruff"
This model of motorized towing vehicle is an extremely reliable piece of equipment, but nothing lasts forever. Most often, owners may encounter the following problems:
- excessive surface milling;
- rapid self-burying of the device;
- track slip;
- reduction in grip and traction qualities;
- the snowmobile began to lift its nose up;
- reducing the support area of the tracks;
- subsidence, fatigue, constriction, cracks of springs;
- increased engine power consumption;
- deterioration of passability on snow or ice;
- Unstable operation of the engine or its complete stop;
- problems in the ignition system, etc.
To fix the most common minor breakdowns, you just need to have a spark plug wrench, a spare ignition coil, spark plugs, and a set of spanner wrenches on hand. What if the damage is more serious? take the device to a service center. We also recommend regularly diagnosing the device and promptly replacing worn parts. Moreover, today you can buy spare parts for “Ruff”. there won't be any difficulties. [ads-pc-2]
Motorized towing vehicle power system
The motorized towing vehicle Ersh 2 is equipped with a Lifan engine. It has a modern four-stroke layout and a power output of 6.5 horsepower. This motor is the most economical and environmentally friendly compared to other units installed on domestic motorized dogs. A centrifugal clutch is used as a transmission.
Gasoline consumption is 1.5 l/h, and the gas tank capacity is 3.5 liters. The power unit allows you to accelerate to 25 km/h. The air cooling system is responsible for the ventilation function of the main components of the internal combustion engine, which prevents the car from overheating at high engine speeds.
Owner reviews
- Igor, Krasnodar region. The car turned out to be universal and suitable for simple off-road conditions. Ruff 2 is suitable for driving on a knurled snow road. The ruff is very maneuverable and high-torque, despite the 6 forces under the hood. Supports 92 gasoline and does not require high maintenance costs. The car looks stylish and compact. Quick assembly and disassembly, efficiency, convenient handling and the ability to transport 100-kilogram loads - this is why I actually purchased Ruff 2. The device is used for fishing, hunting, as well as for short walks with the family and children. Loading the Ruff into the trunk of a car is not difficult. Low maximum speed does not require a license or registration with technical supervision.
- Alexander, Pyatigorsk. I quickly got bored with this toy. It is completely unclear why it is needed. I was not impressed by the ruff at all, I even tried to sell it - no one would buy it. The review is completely negative, since you can count the advantages on one hand. Well, firstly, it is compact in size. The car is even too small, but it easily fits into the trunk of a car. There is essentially nothing to break, but there are already enough problems. For example, very mediocre cross-country ability and smooth ride - you ride as if on a stool. All road irregularities are felt very well. Fuel consumption is no more than 1 liter per hour, but somehow I don’t mind spending money on a cheap AI-92. The mediocre build quality does not affect performance, which essentially does not exist, because the power is only 6 horsepower. The maximum speed is no more than 20 km/h. With these parameters, the best option is to transport the towing vehicle in a car, right up to its destination. But my Lada Niva often breaks down, and therefore it is not always possible to transport it in the trunk. And the river is very far from my summer cottage. I do not advise anyone to take this toy.
- Konstantin, Ekaterinoslavl. Ruff 2 has been in my possession for two years. There are both disadvantages and advantages. The main advantage is, of course, its small size. With such dimensions, you can climb into the wilderness and... get stuck in it until the tow truck arrives. Therefore, compact dimensions are needed only for transportation in the trunk, but in terms of cross-country ability there are only disadvantages. The car does not have enough traction, because the weak 6-horsepower engine is not capable of pulling even 100 kg of cargo - this is exactly how much is indicated in the passport data. The best use of this motorized towing vehicle is on an icy road or on a frozen lake. In such smooth road conditions, the car shows itself in all its glory. In addition, low weight is just what is needed for safe driving on thin ice. Fuel consumption is 1.5 liters per hour, and the maximum speed on ice is about 18-20 km/h. The device does not suffer from breakdowns, because it is structurally simple, easy to disassemble and assemble.
Main differences from other budget motorized dogs
The main advantage of Ruff 2, undoubtedly, is its miniature dimensions. This is useful for those people who prefer to drive to their destination by car and then use the towing vehicle for its intended purpose. Other advantages of the model according to owner reviews:
A category M or A driver's license is not required due to the limited maximum speed. There is also no need to register the vehicle.
Thanks to the wide track, it was possible to increase the maneuverability of the mini-snowmobile. The machine is able to overcome hills, muddy ground, slopes of 30 degrees, ruts and deep snowdrifts. You can safely move on hard and icy surfaces without the risk of slipping or slipping. The layout of the Ruff parts is designed in such a way as to ensure optimal weight distribution - the caterpillar pressure on the surface is on average 35 grams per 1 square meter. cm.
The adjustable steering column of the snowmobile is raised or lowered to a certain position, depending on the height of the driver. You need to move around on a drag sleigh (purchased separately).

Let us briefly highlight the main features of the model:
- Small dimensions
- Good lugs
- Fuel efficiency
- The basic package includes headlights for additional illumination and good visibility.
- Load capacity up to 100 kg (together with the coupling device - drag sleigh)
- The machine is suitable for winter use
- The engine is located in the front for improved center-to-axle weight distribution and off-road stability
- There is no need to purchase a driver's license due to the limited maximum speed. Thanks to this, Ruff 2 is suitable for beginners, including children.
The main advantage of the motorized towing vehicle Ersh 2, undoubtedly, is its miniature dimensions. This mini-snowmobile has proven itself well among users who prefer to get to their destination by car, and then use the towing vehicle for its intended purpose - for example, first get to a river, and then drive out onto an icy surface (using a motorized towing vehicle). When folded, the dimensions of the machine are as follows: 90/55/75 (in centimeters, length/width/height, respectively). The weight of the device is 50 kg, and the assembly process takes a few minutes. When driving on an icy surface, the speed can reach 24 km/h.
In addition to high mobility, as well as ease of assembly and disassembly, we note a number of ergonomic features of the motorized towing vehicle Ersh 2. We are talking about an adjustable steering column, which is raised or lowered to a certain position - depending on the height of the driver. The most optimal way to move is in a standing position, in which you can get maximum riding pleasure. You will need to attach a drag sled, which is one of the most important accessories, but still needs to be purchased additionally.
The chassis deserves special attention, which the developers tried to make stable and reliable, not requiring additional maintenance. Thus, thanks to the wide track, it was possible to increase cross-country ability. As a result, the vehicle is able to overcome hills, muddy soil, 30 percent inclines, ruts and deep snowdrifts. In addition, the width of 300 mm contributes to the stability of the towing vehicle on any surface. At the same time, thanks to this, it is possible to avoid the car tipping over on uneven roads. You can safely move on hard and icy surfaces without fear of slipping or slipping. The layout is designed in such a way as to provide optimal pressure on the ground - with the caterpillar pressure on the surface averaging 35 g per 1 square meter. cm (excluding the load from the driver and passenger). The drag sled in the transport position is a trough, which is installed in the front part. Its function is to transport cargo, as well as throw snow in different directions to improve the track's maneuverability.
