Do-it-yourself motorcycle dog scheme and drawings. Do-it-yourself caterpillar snowmobile attachment to a walk-behind tractor
Do-it-yourself motorized dogs are made today by many craftsmen. These devices are small tracked snowmobiles that can be used to tow sleds. This type of technology became known relatively recently, about 20 years ago, but today it has been able to gain popularity among a wide range of consumers. You can not only purchase equipment, but also manufacture it.
Why is it worth making a motorcycle dog
The equipment is compact, unpretentious and does not imply the need for a separate storage room. If you make such a motorized towing vehicle yourself, then it will be able to make your life easier, this is especially true for fishermen and hunters, as well as lovers of active winter recreation. You can assemble this device from improvised means, this approach will be more cost-effective compared to purchasing a factory-assembled model.
Preparation for work
Before you start assembling a motorcycle dog with your own hands, you must decide on its characteristics. It is important to decide what load capacity the equipment will have, what engine it will work with, and what type of transmission will be used in the design. The mechanic needs to decide whether the engine will start with an electric starter or manually.
When do-it-yourself motorcycle dogs are made, they are usually supplemented with devices that will respond to the owner's requests. This may include:
- winch;
- chain protection;
- extra light.
You may need a motorized towing vehicle in the form of a pusher. All these characteristics will determine the necessary set of tools and materials.
Engine selection and base assembly
At the first stage, the master will have to assemble the frame, on which the engine, chassis and gearbox will be strengthened. For this, a channel or a metal beam is usually used, from one of which it will be possible to assemble a rectangular frame, and for this you need to use a welding machine and an angle grinder. When assembling a motorcycle dog with your own hands, mounts for the gearbox and motor are installed on the frame, and a steel corner should be used. The engine can be anything, it can be borrowed from the Druzhba or Ural chainsaw. This is exactly what the manufacturers of the first motorized towing vehicles did.
However, you can also use a powerful motor, which can be taken from an imported scooter or moped. If we are talking about the Sh-58 engine, its main advantage can be distinguished - the possibility of using a gearbox with manual shifting. If you use a foreign-made engine, then it should be small, it is advisable to prefer a two-stroke engine, because a four-stroke engine with the same power will have a more impressive mass. If we talk about power, then 6.5 liters will be quite enough. sec., this will ensure a speed of 30 km / h, which is true even when driving in deep snow.
Work on the running gear
If you are thinking about the question of how to make a motorcycle dog with your own hands, then you should take care of the control system and chassis. The latter is based on thrust bearings. On a lathe, taking into account the selected bearings, bushings are made, the wall thickness of which should be equal to 5 mm.
They are used to install support bearings at the corners of the frame. The front and rear axles are turned on a lathe, as a result, it will be possible to obtain shafts. In the described design, a larger amount of loads will fall on the back. Therefore, the rear shaft must be made leading, a drive sprocket is put on it, which is fixed by welding. It should be connected with a chain to the gearbox.
Do-it-yourself homemade motorized dogs are made according to a certain technology, which provides for additions to the technique in the form of caterpillars. They can be made from a 22 cm conveyor belt, which is additionally reinforced with metal tires. You can borrow a track from a Buran snowmobile, but to expand the undercarriage, it is cut in half and inserts are made.
Work methodology
Crawler tracks are sometimes made from hardwood or Buran carriages that are sawn and joined with inserts. Pulleys must be installed on the four-speed box and the motor, which are connected by a belt drive. The steering wheel is complemented by built-in controls like throttle and clutch handles, as well as a gear shifter. It is removed from a scooter or moped.
Assembling a motorcycle dog with your own hands provides for fixing the handle on the right side, while the clutch and gearbox shift knob should be on the left. The steering wheel is fixed with the help of two tubes, which should look like the letter P. The resulting fork is fixed to the rear axle with washers, which are strengthened by welding. As a result, there will be no difference in driving a conventional moped and a motorized towing vehicle.
You can change the technology of work. For example, a do-it-yourself motor dog pusher is made using almost the same method, but the difference is expressed only in attachments. For this, components and parts are used that were borrowed from other mechanisms and devices that had previously become unusable.
Using a walk-behind tractor
In the design, you can use a walk-behind tractor, which will form the basis. However, it will be possible to achieve a speed equal to 5 km / h. Two caterpillars must be made from the conveyor belt, and the cord will be single-layer. By using waste plastic pipes, you can make tracks. Using polyethylene, you will need to cut out the leading stars with a jigsaw.
Do-it-yourself motor dog from a motor block is made according to a technology that involves the addition of equipment with a sitting sled. The conductor is made from an old door, on the surface of which it is necessary to fill the glazing beads and bars, the distance between them will be 35 mm. Caterpillars and a tension wheel are put on the drive sprocket.
Conclusion
If you decide to make a motorcycle dog, then the elements are interconnected by corners, on which there is a platform for mounting the engine. The tension wheel will have a diameter of 290 mm. The diameter of the hollow at the leading sprocket is 290 m, the sprocket is put on the axles of the walk-behind tractor.
Given the parameters of the unit, you must select the dimensions of the structures that are made of the channel, angle and pipe. For example, bearings will have sizes of 107 and 205 mm. Sometimes the last parameter turns out to be too large for such equipment, but if spare parts are at hand, then you can use them. Given the diameter of the axis of the unit, it is necessary to select a bearing that is put on the axis.
Motodog is the popular name for a motorized towing vehicle, such a compact model. In the northern regions, this type of equipment is quite popular and is in high demand among motorists. Looking through the sites of alterations on the Internet, you are sure to stumble upon a video of a motorized dog that was designed and posted on the Internet by some craftsman.
A motorized towing vehicle or a motorized dog is suitable primarily for residents of regions where snow lies most of the year and vehicles are unsuitable. A motorcycle dog is a small-sized equipment that does not take up much space and can be transported even in a car. Light weight and low specific pressure on the ground makes the motorized dog an all-terrain vehicle that can cope with any drifts. On the Internet, you can find videos of motorized dogs in deep snow, where it is clearly seen that such a technique does an excellent job even with a very difficult task.
Factory motorized towing vehicles
Factory motorized towing vehicles go along with homemade motorized dogs. Video tests conducted by lovers of such equipment allow you to evaluate all the advantages of using motorized towing vehicles. Among the factory units, one can note Honda, Subaru and our St. Petersburg motorized dog Bars. Video reports posted on the Internet show that our motorized towing vehicles are in no way inferior to foreign ones.
Today, factories are also trying to fill this technical niche, although this was not always the case. Motorized dogs appeared as an alternative to snowmobiles, and the first such machines were assembled by craftsmen. With the light hand of some northern joker, this technique was called a motorized dog, because it is dog sleds that are the main means of transportation in the north.
When the factories began to produce motorized dogs, the name was slightly reformulated and so motorized towing vehicles appeared, which in principle reflects the very essence of this unit.
Making a motorcycle dog on your own is not so difficult and can be done by anyone who is familiar with the technique and knows how to hold the tool in their hands. Drawings of homemade motorized dogs can be downloaded from the Internet, but of course, if you have the necessary skills, you can design it yourself. Drawings of motorized dogs are not particularly difficult, and even a beginner can deal with them.
Engine and control for a homemade motorcycle dog
The most important element of a homemade motorcycle dog is the engine. Usually for these purposes, engines of mopeds or small cars are used.
Internal combustion engines produced by foreign concerns are in particular demand - these are Honda and Yamaha due to their economical fuel consumption. By the way, it is worth noting that these engines are very popular due to their versatility and are suitable for creating motorized towing equipment, walk-behind tractors or even mini power plants.
For a homemade motorcycle dog, it is better to choose two-stroke engines. In contrast to the four-stroke ones, they have less weight and small dimensions, which is important, but they have about the same number of horses.
You can choose different controls for a motorized dog, but the steering system with already built-in throttle, clutch and gear knobs from old motorcycles is best. A good and rather simple motor dog is obtained from a motor block.
Caterpillars for motorized dogs
If you have ever thought about how to make a motorized dog with your own hands, you have been faced with the question of a bundle of caterpillars, because motorized dogs are designed to ride in the snow and wheels will not work here.
One option is to take a transport tape and make homemade tracks from flat wooden slats. To reinforce the tracks, it is recommended to use steel combs that are attached to wooden bars. Fastening of the entire caterpillar assembly can be done using carved bolts. Detailed photos of the motorcycle dog in the process of the entire assembly can be found on the sites of alterations
Motorized dog control
The process of driving a motorized towing vehicle is similar to driving a motorcycle or moped. Just like on a moped or motorcycle, the throttle, clutch and gear selector are located on the handle. The handlebar is usually attached to the belt with two pipes welded to the fork.

The overall design is not complicated and it is within the power of everyone who knows how to hold the tool in their hands to make a motorized dog with their own hands (see the drawings and explanations at the end of the article).
The great popularity of light motorized towing vehicles is due to the fact that, coupled with a fairly compact size, they have excellent cross-country ability, are unpretentious in maintenance and consume little fuel.
Let's try to figure out what a motorcycle dog is? In fact, this is a small motorized tracked unit that is designed to tow small loads.
Engine selection and installation
The most important element of homemade products is the engine. In our case, we chose a fairly common domestic Sh-58 moped motor, the main advantage of which is that it is designed to use a manual gearbox switch.
Homemade motorcycle dog
It is also worth noting that foreign-made engines can be successfully used in homemade motorized dogs. Especially, small-capacity engines of the Yamaha and Honda companies are in demand.
The main feature of these internal combustion engines is versatility, they are great not only for creating a homemade motorized towing vehicle, but also for a large number of other devices, from small power plants to homemade motor blocks.
As for the number of cycles, two-stroke engines are best suited for, which, compared to their four-stroke counterparts, have smaller dimensions and weight, while their power characteristics are approximately the same.
Do not forget about the controls of the motorized dog. Here, a steering wheel with built-in controls is best suited, i.e. with a gearshift switch, a throttle and clutch handle from an old motorcycle.
Before starting the assembly of the chassis, it is necessary to select thrust bearings, after which bushings are machined under these bearings. As a supporting structure, a welded frame is used, consisting of water pipes of various diameters. To give the pipes the desired shape, they are pre-filled with dry sand and tightly corked with plugs.
Consumption no more than 2 liters per 100 km
Then the workpiece is placed in a vice, and slowly, using a blowtorch, it is bent in the right places. In order for the bend to turn out to be even, a reference template made of plywood is used.
After all the elements of the frame have acquired the desired shape, they are fastened with welding tacks.
This is done specifically so that in the event of defects at the assembly stage, they can be easily corrected. After all defects have been eliminated, the frame is finally sealed by welding.
For mounting the engine on the frame, sheet steel blanks are perfect. Such blanks are made according to cardboard templates previously fitted to the frame. First of all, the blanks are fixed on the engine, after which the resulting structure is attached to the frame with welding points. Then the engine is disconnected from the workpiece and finally welded to the frame.
Our caterpillar block will use collapsible shafts made of bushings, bearings and the shaft itself. As mentioned earlier, bushings are specially machined for bearings, while the thickness of the bushing walls should not exceed 5 mm. Due to the fact that the largest load in a homemade motorcycle dog falls on the rear axle, we make it the leading one. To do this, a drive sprocket is welded to the rear shaft, which is connected to the gearbox via a chain drive.
In addition to compound shafts, compound wheels are also used in motorized dogs. Each of these wheels consists of two 3 mm thick cheeks and several dozen lugs made of small steel pipes. In order for the wheels to better dampen vibration, rubber bushings are inserted into the ends of the lugs.
mover
For the manufacture of caterpillars, a conveyor belt with a width of at least 220 mm is best suited. Trucks for our walk-behind tractor are made of flat birch slats 1260 mm long. To strengthen the design of the tracks, you can use steel combs that are attached to birch bars. Track parts are fastened with M6 threaded bolts.
Homemade caterpillar
The process of driving a homemade motorized dog is practically no different from driving a moped. On the right handle of the steering wheel is the throttle handle, and on the left handle is the clutch and gearshift lever. By the way, the steering wheel is attached to the frame with two pipes, which in turn are welded to the U-shaped fork. The fork itself is attached to the rear axle of the walk-behind tractor with the help of steel washers welded into it.
Due to the fact that the motor of our motorized towing vehicle is located inside the caterpillar, it cannot be started using a standard kickstarter, so it had to be slightly modernized. To do this, you need a sufficiently long piece of pipe, at the end of which we make a slot of such a size that the lever drive can easily enter it. Then, using conventional welding, we fasten the pipe and the kickstarter lever.

A motorized towing vehicle or a motorized dog is a necessary thing for a hunter. This type of transport can be purchased at a specialized store, but the prices for such equipment are high. There is a way out: you can assemble the product yourself, then the costs will be small. In order for a do-it-yourself motorcycle dog to be made with high quality, to serve for a long time, you need a detailed diagram and drawings, a number of tools and parts.
What is a motorized towing vehicle - description and purpose
A motorized dog is understood as a mini-snowmobile (mini-snow and swamp vehicle) with an engine. This vehicle is a hitch from a caterpillar towing vehicle with a sled or drag sled. The driver of the motorized dog gets into the sled, and any load is put there. Some models of "dog" have a special cargo area on the tractor. Engine power is usually from 6 liters. With. up to 13 l. with., the speed is 30-40 km / h. The motorized dog does not have a brake, which the driver should always remember.
Motorized towing vehicles are popular among fishermen and hunters. They can also be used in agriculture and forestry for the transport of small loads. Unlike wheeled vehicles, motorized dog sled skis allow you to move even on loose snow, winter off-road, than a vehicle resembles a snowmobile. The only difference is in the location of the driver: they sit outside the platform with the motor, which reduces the weight of the motorized dog and increases the cross-country ability. Also, the advantages in comparison with a snowmobile are the simplicity of design, lower price.
On motorized dogs you can move on the frozen surface of the reservoir - lakes, rivers. They are ideal for ice fishing enthusiasts and have been designed specifically for them. It is easy to transport the car in a car using a cover, unload it on the shore, and then use it for its intended purpose. On a motorized dog it is possible to transport goods over rough terrain, replete with descents and ascents. They use the technique for trips in summer, spring, autumn through swampy glades, forest paths.
Why it is worth making a motorcycle dog - reasons
Both purchased equipment and homemade products are unpretentious, compact, do not require much space for transportation and storage. But some hunters prefer to make motorized dogs on their own, from improvised means. The main reason is economy: a home-made version will cost an order of magnitude cheaper. No more than the cost of the simplest tug from China, you can also build a reliable, durable pusher tug.
Many models of motorcycle dogs, especially those made in China, have a lot of flaws in the design. For example, a caterpillar can often become clogged with snow, which is due to the mistakes of the developers. Other possible problems are motorcycle dogs rearing up, burrowing in too deep snow, throwing snow into the sled. All these troubles can be avoided if you make the vehicle yourself.
With a front-mounted engine of a motorized dog, which is almost always planned in home-made models, the operation of the machine will be much more efficient. Here are the obvious benefits:
- fuel economy and overall cost savings;
- higher speed of movement;
- the ability to make additional compartments for gear.
The main elements of a motorcycle dog
The most important piece of technology is the engine. Usually, a single-cylinder carburetor gasoline engine is used to create a motorcycle dog. An equally important part is a rubber-metal caterpillar - a mover with a suspension. With the help of a caterpillar, you can drive on snow, ice, soft ground in warm weather. It is worth considering in more detail all the components of a motorcycle dog.
Machine engine
Most often, engines of the Honda, Yamaha brands (expensive) or Chinese brands (MTR, Lifan and other budget ones) are used for motorized dogs. These power units vary greatly in price, although their power is usually equivalent. The Lifan engines with a centrifugal (dry) clutch have proven themselves well. Some use a motor from a motoblock to create a motorized dog, remove the engine from the Ural chainsaw, Druzhba saw.
The motor from the Sh-58 moped, designed for manual switching of the box, is considered popular. You can also use engines for scooters. The main thing is that the product has good traction characteristics, a power of at least 6 liters. With. This is enough to transport one person and a load of 30-50 kg on a motorized dog. For a trip of two people and a load of 150-200 kg, it is better to choose an engine with a capacity of more than 9 liters. With. As an element of tuning the motor, a chain tensioner is often used.
Bearing frame of the motorized dog
The frame must be of excellent quality, because on the way it experiences high loads, especially when driving off-road. This design is done entirely by hand, cooked from metal pipes of rectangular section. Usually a pipe thickness of 3 mm is enough, thinner metal is not suitable, it quickly deforms.
How to make a frame with your own hands, you can look at the photo, video. They take two pipes with a section of 20 * 20 mm, supplement with two more sizes of 20 * 40 mm, form a frame. Two corners of 40 mm are welded into it, a protective frame for the engine is welded on top, which will prevent it from being damaged when the equipment rolls over. It is also desirable to attach a galvanized sheet with rivets to the frame to close the caterpillar.
Motorized dog suspension
Suspension is an important indicator of running gear performance. By design, it can be roller, slip. The roller shows itself worse in the snow, but it is ideal for driving in the warm season. The suspension on the slides does not allow the tracks to clog, but is only used in winter: it needs snow to cool the system (ski module).
For home-made motorized dogs and trips in any season of the year, it is worth choosing a modern roller suspension, but not with rigid, but with spring-supported rollers. Such a motorized dog will move more gently on a frozen road. When driving, you will have to avoid too loose snow.
Motorized dog transmission
The transmission is responsible for transmitting the rotation of the shaft to the main track sprocket. The box can be CVT, mechanical, automatic gear, some have a reverse (possibility of reverse). The advantage of automatic transmission is a large traction force, a minus is the rapid wear of a number of parts, the need for regular maintenance.
As a mechanical one, you can use a box from a VAZ, another old car. Its plus is ease of maintenance, no need for frequent repairs, but the use of such a transmission is less comfortable. The variator provides a smooth transfer of power from the engine to the track, which helps to reduce the wear rate of parts and save on gasoline. Minus - a weak drive belt, which has to be changed regularly.
Motorized dog caterpillar
Such devices can be snowmobile and specialized, designed specifically for motorized dogs. They differ in width, height, length. On sale there are replaceable caterpillars from snowmobiles that can be used in the manufacture of motorized towing vehicles. Caterpillars from Buran are popular, but they do not differ in high cross-country ability; motorized dogs will only have to be operated on a frozen pond, a well-knurled road.
Acquire should not be too narrow caterpillars. A product of 50 cm is considered optimal, since it makes the motorized dog stable, passable, and maneuverable. There are also “aggressive” cross-country tracks on sale, their width is from 55 cm, a special tread pattern is made. The products have an increased height of the lugs - it is 32 mm (the standard is 21 mm). You can also make caterpillars yourself from a conveyor belt. Trucks are made of birch planks and other materials.
Electrical equipment and control systems of the machine
To control motorized dogs, they use a steering wheel that has a connection with the gearbox, clutch handle, gas, which should be taken from any suitable old equipment. Usually, in the basic configurations of tugs, a manual start is equipped, but if desired, it can be changed to an electric starter, add a lighting coil. All this is easily built independently, but the cost of manufacturing a motorized dog will increase.
It is quite possible to do without an electric starter, besides, manual start is considered more reliable in terms of breakdown. But without lighting at night on a motorized dog it will definitely be bad, this system must be provided for. The car must be equipped with a 7 amp coil so that there are no problems with feeding the headlights.
Self-made motorcycle dog: technology
Before starting work, you need to prepare all the necessary tools and equipment for a motorized dog. You can learn more about the progress of work by watching the thematic video.
Preparation for work
In order to avoid problems with the use of a motorized dog, it is important to immediately determine its main technical parameters:
- carrying capacity;
- engine power;
- transmission type;
- engine start system - manual or electric.
You should also think about the additional accessories of a motorized dog - a winch, lighting, protective elements, seats. Then an exact drawing is drawn up, which will reflect all the nuances. Then you can order a set of parts for a motorized dog or pick them up yourself from those available from other equipment.
Required Tools
When working, you can not do without a welding inverter, a drill and a grinder, a set of wrenches. Also, for mounting a motorized dog, you will need screwdrivers, a file, and other small tools. The master must have access to turning, milling machines.
Assembling a motorcycle dog
First, a motorcycle dog frame is made, which will help to fix the engine, box, walker. For this, selected pipes (a beam or channel is also suitable) are welded into a rectangular frame. Then, fasteners are welded for all the important components of the motorized dog. After you can install the engine.
The undercarriage must be based on support bearings. On a lathe, the corresponding bushings are machined with a wall thickness of 5 mm. Using bushings, bearings are placed at the corners of the frame. After that, the front, rear axles are made, which will form the shafts together with bushings and bearings. The rear shaft of the motorized dog is made leading by putting a drive sprocket on it and welding it securely. It must be connected to the gearbox with a chain.
Motor dog caterpillars are made independently from a conveyor belt more than 30 cm wide or they are taken ready-made, but the latter will have to be cut and expanded with inserts. Tracks are made from wood, plastic pipes or removed from an old snowmobile. Pulleys connected by a belt drive are placed on the box, the motor. The control elements of the motorized dog are attached to the steering wheel - the clutch handle on the left side, the gas handle on the right. The steering wheel is fixed to the frame with two pipes by welding with a fork. The latter is located on the rear axle and is fixed with welded steel washers.
At the end of the work, additional devices of the motorized dog are mounted, the necessary equipment is hung. The design is complemented by a seating area, a compartment for cargo, etc. The finished product will not be inferior in quality to store equipment, but it will be made reliably and can be repaired in case of breakage by the master himself.
