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.

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.

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.
