Due to the fact that we sell only two types of weights for the 157QMJ engine, one is standard, as supplied from the manufacturer, the other is heavy, completely corroded with bronze. And I decided to make my own in different weights! In the next topic you have already seen how I turned ordinary standards into heavy loads, this is how factory ones were used. This is where the idea of loads made exactly the way I wanted came to me! With any weight, for better transmission tuning! Why was the fluoroplastic material taken?
From Wikipedia: Fluoroplastic is a polymer material produced chemically. Fluoroplastic contains fluorine atoms, due to which it has high chemical resistance. Poorly soluble or insoluble in many organic solvents, insoluble in water and not wetted by it.
Fluoroplastics are characterized by a wide range of mechanical properties, good dielectric properties, high electrical strength, low coefficient of friction, low wear values; resistant to various aggressive environments at room and elevated temperatures, weather-, corrosion- and radiation-resistant, weakly gas-permeable, non-flammable or self-extinguishing upon fire. Very high heat resistance (up to 300 °C). The material has cold fluidity.
So the material itself very much satisfied all the necessary characteristics; I had a piece lying around since Soviet times, so it came in handy. But as far as I know, you can buy it in hardware stores, and gaskets are often made from it to replace copper ones. Well, that's not the most important thing. So I took this piece of fluoroplastic to the operator, handed over the dimensions and in the end we got the following 12 weights, from which two sets of weights can be made:
Since the material is very light, they could not be used in this form. But the interest was great and for the sake of this the variator was quickly disassembled (by the way, this is all done within 20 minutes. Disassembly-replacement-assembly). The results were not so much unexpected as they were cool. He was tearing it out from under him! polished and burned rubber! The engine speed was simply unrealistically crazy! But the speed never rose above 30 km per hour! Well, it was interesting to experiment! And naturally, as often happens in my head, the idea did not take long to arrive! I note that this time there was not even “doping” and “idea generator” in the form of beer! Anyway! The main thing is the end result. What I did in 6 weights was to drill 10 holes and cut threads in them, and in the other 6 weights to 8 holes. The result is the following:
I’m still thinking about what to do with them next, either fill them with lead, or screw the bolts in there and cut off the caps. In general, once I decide and do it, I’ll post the overall result.

Calculation and assembly of caterpillars
Do-it-yourself homemade snowmobile from a walk-behind tractor: homemade video
The caterpillar is a tape, on the outer surface of which the tracks are attached. Tracks are rigid lugs installed along the entire length of the tracks. Track options:
- Made from 3mm thick transport tape.
- From a car tire.
- From V-belts.
- Ready-made factory-made tracks.
The conveyor belt must be looped. Its strength is only sufficient for light snowmobiles with engines no more powerful than 10 liters. With. Car tires are stronger than tape and are suitable for powerful engines. Solid tires do not need to be looped, so the likelihood of a rupture is minimal. It is more difficult to choose a tire of the required length than a tape.
Finished tracks are removed from other similar equipment (snowmobiles “Buran”, “Sherkhan”). They are equipped with lugs from the factory. The products are not suitable for use with low-power motors from walk-behind tractors. Homemade snowmobiles made from Buranovsky tracks must have gears from the same “donor”.
The size of the caterpillar is selected according to the required driving characteristics: the larger the width, the lower the handling, but the higher the maneuverability. The minimum area of the contact patch from the snowmobile (skis and tracks) must be such that the pressure from the equipped vehicle does not exceed 0.4 kg/cm2 of surface. Light snowmobiles use a 300 mm wide conveyor belt, cut lengthwise into 2 strips of 150 mm each.
Preparing the Tape
The tracks are attached to homemade tracks with M6 bolts with a wide head. The bolts are fixed with a nut, a washer and a groover are used. Before fastening, leading holes with a diameter of 6 mm are drilled in the tape and tracks. When drilling, use a jig and wood drills with special sharpening.
The conveyor belt is also looped with M6 bolts. To do this, the edges of the tapes are overlapped with an overlap of 3-5 cm, the connection contains 1-2 rows of bolts. For a 150 mm wide track, the following distances are maintained:
- From the edge of the tape 15-20 mm.
- Between bolts on tracks 100-120 mm.
- Between the bolts when banding 25-30 mm.
Homemade lugs
The tracks are made of polyethylene pipe with a diameter of 40 mm with a wall thickness of 5 mm, sawn in half in the longitudinal direction. The entire section of the lug is adjacent to the tape. In light snowmobiles, one track connects the tracked pair. With a track width of 150 mm, the track length is 450-500 mm.
The lugs are cut using a wood circular saw. They use a special machine with two guides (metal and wood), rigidly fixed on a fixed tabletop. The walls of the pipes are sawed one by one.
The distance between the tracks depends on the parameters of the gears on the drive shaft. Typically 5−7 cm. The specified distance is maintained with an error of no more than 3 mm. Otherwise, the operation of the drive is disrupted: the lugs “run” onto the teeth of the drive wheels, the caterpillar begins to slip and fly off the rollers.
Which chainsaw should you choose?
How to make a homemade plow for a mini tractor
To create a snowmobile, you can use various chainsaws. The most suitable options would be the Druzhba, Ural and Shtil models. And which unit to choose - it all depends on your desire.
Friendship
The main positive side of using the Druzhba chainsaw as a starting material for making a snowmobile with your own hands is its simplicity of design. Here is an elementary assembly, where each part plays its role. No extras, just the essentials.
The negative aspects of this unit include its heavy weight. Moreover, the use of safety covers is not provided here. And in general, the chainsaw is already obsolete.
Technical certificate:
- power – 1 kW;
- weight - up to 12 kg;
- engine (two-stroke);
- tire length – 45 cm;
- fuel (gasoline).
Ural
The specialized professional chainsaw "Ural" was created specifically for felling tree trunks. This is a very convenient mechanism in operation, characterized by great power. This unit is an environmentally friendly device that can be used even in harsh winter conditions.
If you decide to use a Ural chainsaw to create your own snowmobile, this is the right choice. Since the technical parameters of this machine fully meet the stated requirements.
Technical certificate:
- engine (gasoline, two-stroke, single-cylinder);
- power – 3.68 kW;
- weight – 11.7 kg;
- parameters – 46 x 88 x 46 cm.
Calm
The Shtil chainsaw is also suitable as the main mechanism for creating a snowmobile. It is made of environmentally friendly material, harmless to humans, has good power and operates silently. Therefore, your trip will be very comfortable.
Why do you need a drawing?
How to make a homemade earth drill (pit drill, earth drill)
Assembling a snowmobile begins with a plan, that is, with a drawing. It is recommended to do it yourself, taking into account the non-standard and unique nature of the planned man-made mobile vehicle. Here it is necessary to remember that this working diagram is needed for internal use, therefore the level of drawing art does not matter, but the main thing is how clearly the plan will be embodied in the diagram
When drawing up a drawing, it is important to take into account the weight of the structure: the lighter the snowmobile, the higher its maneuverability will be.
Frame
According to an individual drawing, the frame is welded in the form required for this version of a homemade snowmobile. Wooden bars or metal pipes are used as the starting material. The easiest way is to make a wooden frame. Its main advantages are that it is easy to repair in the field (there is a lot of wood around), and it holds the car well on ice. The metal frame is welded from pipes of a certain square section, the size of which depends on the load. Its advantage is that it is a stronger and more durable structure than a wooden one. As always, there is a ready-made option - take a frame from a moped.
Track assembly
After making the frame, they begin to create tracks, consisting of tracks and rigid hooks installed along their entire length. Caterpillars can be made from conveyor belts or car tires. You can use ready-made industrial tracks. An advantage of purchasing ready-made tracks may be their special regional purpose, where climate, terrain and travel conditions are taken into account.
Wheels are installed inside the homemade tracks. With their help, the tracks on which the lugs (or simply hooks) are located rotate.
A common option for their manufacture is plastic pipes. They are cut into pieces
The lugs are attached to the tracks with bolts, and it is important to maintain the same distance between the lugs so that they do not disturb the movement of the caterpillar
The wider the tracks, the more difficult it is to control the vehicle, but the higher the maneuverability becomes. The thickness of the tracks must correspond to the engine power.
Chassis
After the frame and tracks are ready, they begin to assemble the structure with the chassis.
- Using front suspensions, the steering and skis are attached to the frame.
- The steering wheel is often taken from a motorcycle or scooter, but in case of non-standard solutions, it is assembled independently, based on personal preferences and convenience.
- Skis are often used ready-made. Typically, a ski consists of the following parts: base, shock absorber, link leg, fork, its rod and bipod. But there are options for making your own: from plywood, plastic, metal.
- The rear suspension connects the engine to the tracks.
- A motorcycle chain can be used as a drive.
- The fuel tank is chosen based on safety, economy and practicality. The capacity of the container (made of plastic or metal) is determined by considerations of the necessary distances to be overcome.
- The seat is made to order according to individual preferences, since the control of the snowmobile will depend on convenience and comfort. The best choice is a seat made from quality materials.
Frame and body
Before work, it is recommended to draw up a drawing of the frame. The structure is welded from a square pipe 25 x 25 mm with a wall thickness of 2 mm. For a payload of over 150 kg, the section size is increased to 30 x 25 mm. The loading area and body elements are covered with plywood. The seats are selected with a hydrophobic coating.
In the center of the fracture frame there is a hinge that allows rotation around a vertical axis. The maximum rotation angle is limited by welding metal plates. The front half is used for steering, and the engine is placed on the rear half frame.
The solid frame is welded in the form of a rectangle, inside of which axles and tracks are located. The engine is placed in front on a special platform, rigidly welded to the rest of the frame. In both cases, the motor is installed in the transverse direction (the shaft faces the end).
Other creation options
There are other ways to build a snowmobile using skis or a crawler rear. These makeshift snowmobiles and snowbikes use bicycle wheels.
Snowmobile from scooter
One of the simplest homemade options you can create yourself from any scooter or moped. The only differences here are the frames, the sizes of the tracks, and other parts. Such a snowmobile is unlikely to be powerful and will have difficulty moving through snow-covered snowdrifts. Therefore, they use wheels of a smaller diameter and increase the frame. This homemade moped moves well on light snow or crust. In the spring, you can replace the ski or track back with wheels and get a scooter or moped again.
Chainsaw snowmobile
Using a motor from a trimmer, many craftsmen can independently make various devices: cultivators, motorbikes, snowblowers and, of course, snow scooters (or snowmobiles).
The product is not particularly powerful, but reliable, lightweight and easy to use.
Snowmobile from a motorized dog
It is even easier to get a snowmobile from a motorized towing vehicle or a motorized dog; there is practically no need to reassemble it - just add skis with steering and make minor changes.
Snowmobile from ATV
The ATV undergoes even less alteration for better maneuverability in winter snowy terrain. Essentially, everything is limited to tuning, which consists of installing tracks, although this process is expensive and time-consuming.
Snowmobile on tubes
About homemade products using cameras or pneumatics has already been noted above. The homemade device consists of a control support ski and a leading support pneumatic.
The advantages include the high cross-country ability of the vehicle, and the disadvantages include low maneuverability.
Transformable snowmobile
A folding snowmobile is called a mini snowmobile or transformer. Its main difference is convenience and ease of use. It easily fits when folded in the trunk or even on the seat of a car.
Snowmobile from a cultivator
And another savvy option for inventive use - a snowmobile made from a cultivator. Usually, every farm has a cultivator and sits idle in the winter. Using the engine according to the assembly diagram, we make an apparatus for winter movement. The power is small, but in reality it is practical and effective.
How to make a homemade snowmobile from a chainsaw?
The axis of the rollers can be borrowed from a potato digger. Their ends need to be released a little. This is done so that the axles can be sharpened and threads of 10 mm can be cut. When making a homemade snowmobile from a chainsaw, do not forget about the spacer bushings. They should be placed directly on the axes of the unit. It is best to take bushings made of duralumin pipe. Next, the axles are secured using fastening bolts or a locknut. Using the same principle, a homemade snowmobile is assembled from a Druzhba chainsaw.
At the next stage, it is necessary to weld 3 racks made of steel angle to the spar. The best option would be corners measuring 30×30 mm. They also need to be connected with steel crossbars. This way the structure will form a small portal. Make a platform between the front part and the middle on the right side - weld a 2 mm steel sheet. After this, place the chainsaw gearbox and the intermediate chain drive shaft here.
The front part of the frame must connect to the front axle crossmember. As a beam, you can use a regular water pipe with a diameter of at least 30 mm.
Those who made homemade mini-snowmobiles from a chainsaw take the tracks from the old Buran. However, for it to function normally, it needs to be shortened slightly (by 500 mm) and sewn together with transport tape. Make the gears from a 15 mm nylon sheet.
It will be tubular type with a diameter of 28 mm. A round flange with holes for the gears should be put on it. Press and weld solid pin tips into the ends of the drive shaft. The latter must be machined for bearings.
The dimensions of the tension shaft tips must be the same and fastened similarly to the drive devices.
Snowmobile from a motorcycle: a guide for masters
Making a snowmobile from a motorcycle is not so easy. If the assembly of previous products did not cause any difficulties, then with this design you will have to suffer. The work will require not only tools, materials and equipment, but also skills in working with a welding machine and other equipment.
Snowmobile design technology
- A suitable frame is made from metal pipes of different diameters and steel corners. Its base is made in the form of a rectangle (its dimensions are 150 x 43.2 cm).
- The steering beam is constructed from metal corners (its dimensions are 50 x 50 x 5 mm), its parts are sheathed with dense metal overlays. The finished structure is installed in a horizontal position on a drilling machine.
Motorcycle Izh
- The frame and the finished beam are processed at the joints, special grooves are prepared for reliable fixation of the elements.
- The front crossbar of the frame is equipped with a strong corner.
- The seat is attached to the frame of the structure.
- Make holes in the side members.
- A channel is welded between the steering and middle sections.
- Select a suitable track sprocket and rubber band for further installation (suitable dimensions - 2200 x 300 mm, thickness - no more than 10 mm).
- The caterpillar itself is carefully sheathed with nylon so that the material does not delaminate during use.
Snowmobile from motorcycle
- A transmission is installed, which consists of a front and rear axle. The front one is the drive one, it consists of a tubular shaft, a track sprocket and rollers (the sprockets themselves are fixed with through bolts). The rear axle structure consists of a track drum and a tubular shaft.
- The skis are welded to the structure of the snowmobile (sheets of steel and metal corners are used for their manufacture).
The control system of a homemade snowmobile from a motorcycle is quite complex to design. It consists of:
- skis;
- longitudinal traction;
- lateral thrust.
Important! Experts do not recommend changing the motorcycle steering system; all controls must perform their original functions. From the information presented we can conclude: a homemade snowmobile from elements of a walk-behind tractor, chainsaw or motorcycle is a reality
Any craftsman can make it. For productive work you will only need certain skills, equipment, tools and materials

DIY snow scooter skis
Often during operation the vehicle breaks down or the ski is damaged. You can buy it or make it yourself, especially if it is the front one. Of course, preliminary preparation will be required. Not many people go to the extent of making them themselves, but if everything has already been decided, you can get started. The process of making a product is not so easy. It is recommended to follow the instructions step by step:
- you will need thick frost-resistant plastic;
- measure the size of the broken ski;
- draw and cut a blank from plastic? this can be done with a hacksaw or using a wood cutting machine;
- to smooth the angles, the ski is sharpened on the sides with a file;
- heating near a source of strong heat, bend the ski slightly so that it does not “dive?” in snow, to avoid cracking, do not allow sudden cooling;
- attach the ski to the place of the broken one.
Walk-behind tractor base design
You can make a snowmobile from various equipment, for example, a moped, scooter, trimmer, etc. However, the best choice can be considered a walk-behind tractor. Since this unit remains unclaimed in winter, it can be safely taken as the basis for creating a snow scooter. The snowmobile attachment can be made on wheels and this design is simpler. The most difficult thing is to make a snowmobile with your own hands from a walk-behind tractor on tracks. However, it has higher cross-country ability, which can become the main criterion when choosing the type of structure.
It should be remembered that not every walk-behind tractor can be converted into a snowmobile. It is best to use units equipped with:
- Rear towing device.
- Medium-power air-cooled power plant.
The optimal choice can be considered Neva units. They are attractively priced and their engines are assembled in Japan. The design of a self-assembled motor sleigh can be divided into two main parts - the driving and driven ones.
The first category includes the motor from the walk-behind tractor, drive elements and the supporting frame. The driven part consists of:
- Steering column.
- Shock absorbers.
- The chassis, for example, is tracked.
Frame making
You should first study the drawings well. If you wish, you can make a mini snow scooter of your own design, but many people prefer ready-made solutions. To make the frame, you should use iron pipes. To give them the desired shape in accordance with the drawing, you will need a pipe bender. When this work is completed, it is necessary to connect all the frame elements by welding.
The next step is to fabricate the main subframe structure at the front. This is where the power plant and gearbox, for example from a Zhiguli, will be mounted. To solve this problem, a stand with holes for the motor is welded to the frame. The drive chain is installed in a special slot.
Chassis
One or two skis must be attached to the steering column using a swivel joint. It is better to use ready-made shock absorbers for the front suspension, for example, from a motorcycle. You should also decide whether tracks will be used for movement, or whether you plan to make a mini snowmobile on inner tubes. Each of these drive types has not only advantages, but also disadvantages.
The wheeled unit is more maneuverable, but is inferior to the tracked unit in cross-country ability. Tracks can be made independently from various materials, for example, a conveyor belt.
How to make a snowmobile from a chainsaw with your own hands?
The very first step when assembling a snowmobile with your own hands should be to develop a drawing and diagram. So, you will see what spare parts and parts you can get from where, what you need to assemble, buy, and so on.
Next, you need to disassemble the selected chainsaw, prepare other components, fasteners, components and spare parts. This way the work will not stand still, and all the necessary parts will be at hand. For additional information, you can watch a video on how to assemble a snowmobile from a chainsaw with your own hands. This way you will have a better understanding of the design and structure of your homemade machine.
How often do skis break?
When answering a consumer question about how often skis on a snow scooter can break, we can consider some situations. In the first case, it is a low-quality snow scooter. They also break due to overloads and frequent damage. It all depends on the area and the period of their operation. We must not forget that it requires special care, like any other equipment.
To ensure the strength of snow scooter skis, manufacturers produce additional pads. Their direct responsibility? protection from external damage. But they also cannot guarantee a 100% positive result. Another feature is additional stability and better maneuverability of the snow scooter. They help the vehicle slide more easily on snow.
Speaking about snowmobile skis, we need to mention a few more points:
- Manufacturers in most cases use special reinforced plastic or metal;
- Should the tip of the ski be high? This is a guarantee that passing obstacles will be easy.
By choosing a high-quality snow scooter and the appropriate components, you can be sure that the problem of ski breakage will not bother you.
It is recommended to purchase spare parts and additional products in specialized stores. There you can find a variety of models that are suitable for a given vehicle. Main ? know its characteristics and features. [ads-pc-1]
Which chainsaw is suitable for these purposes?
In order to make your own snowmobile from a chainsaw, you will need, in fact, a saw. You can take any brand and model that is in stock. Craftsmen recommend using the Druzhba, Ural or Shtil saws, as they are most suitable in terms of technical characteristics and differ in the quality of their engines.
Friendship
The advantage of the Druzhba saw is its simplicity of design and therefore it is very convenient to disassemble. In addition, the tool does not have any unnecessary bells and whistles that modern saws can boast of and which only interfere with the assembly of the snowmobile. But there are also disadvantages - the Soviet saw is heavy and outdated.
Chainsaw Friendship
Its technical characteristics are as follows:
- power – 1 kW;
- weight - up to 12 kg;
- engine (two-stroke);
- tire length – 45 cm;
- fuel (gasoline).
Ural
The excellent technical qualities of the Ural professional saw are perfectly suited for creating a homemade snowmobile on its basis. The mechanism is powerful and efficient, and is also adapted for use in cold conditions.
Chainsaw Ural
Technical data
- engine (gasoline, two-stroke, single-cylinder);
- power – 3.68 kW;
- weight – 11.7 kg;
- parameters – 46 x 88 x 46 cm.
Calm
The Shtil chainsaw also has sufficient characteristics to be used in a homemade snow scooter design. The most important thing is that the chainsaw has enough power to start the snowmobile. In addition, the Shtilevsky engine is characterized by quiet operation, which will give additional comfort to movement.
Chainsaw Stihl MS 180
What skills are needed?
You don’t need any special skills to assemble a homemade snowmobile, but it is advisable to know how to work with welding and have a welding machine. To use the diagrams and drawings provided, it is advisable to be able to understand them.
Chainsaw snowmobile
Before you start making a snowmobile from a chainsaw, you need to choose equipment that will have all the necessary characteristics. The best option for this purpose is the Druzhba, Ural and Shtil chainsaw (the power of these tools is ideal for creating high-speed snowmobiles).
Important! The engine and gearbox are the main parts of the chainsaw that are used during operation. The snowmobile design consists of four parts:
The snowmobile design consists of four parts:
The assembly of a homemade snowmobile is carried out not according to some proposed scheme or standard drawing, but based on the materials and tools that the master has at his disposal.
Instructions for assembling a snowmobile from a chainsaw
Assembling a product is quite an interesting job. It consists of several successive steps that must be performed carefully and responsibly.
The first stage is the assembly of the frame base of the future homemade snowmobile. For work you will need steel corners (size - 50 x 36 cm) or steel sheets (thickness - at least 2 mm). The middle part of the structure is made from the corners, and the front and back are made from sheets.
Carefully make two through holes to accommodate the track shaft and track wheel guides (tensioners are installed on both sides of the side members).
Important! The front device is specifically designed to tension the second stage of the idler gear, it also helps in adjusting the track itself
- Special brackets are carefully welded to the bottom of the side members (they are attached at the same distance from each other), support rollers are installed in their open grooves.
- The rollers (in rubber covers) are placed on five axes, each of which is attached to the underside of the open grooves.
- Between each of the elements special bushings made of duralumin are installed (they are made from a suitable pipe).
- The bracket axles themselves are secured using nuts and locknuts (they are designed to strengthen the snowmobile frame and hold the side members at a certain distance from each other).
- Three metal corners are used to make racks for attaching the prepared chainsaw gearbox, and install the intermediate shaft of the chain drive.
- A seat for the user is installed on the prepared frame (a suitable box or car seat is used for these purposes), it is fixed in the area between the middle and rear parts of the structure.
- A hole is made in the front section of the frame to accommodate the steering wheel; it is made from a pipe with welded control handles.
- Metal gussets are installed in the places where the snowmobile racks are attached (they strengthen the structure, make it stronger and more reliable).
Important! In order for the future homemade snowmobile to have good maneuverability in snowy terrain, it is equipped with a caterpillar mechanism
- A snowmobile drive shaft is made from a metal pipe, and a special round flange is inserted into it for attaching gears.
- To create the steering, equipment from old motorcycles or mopeds with three-lever control is used.
The finished snowmobile is light in weight and can easily be placed in the trunk of a car for transportation over long distances. Its controls are so simple and intuitive that even a child can easily use it.
Tips for using a homemade snow blower
Before starting work, warm up the engine and use seasonal lubricant.
Also follow some guidelines.
- Operate the snow blower at full capacity.
- Avoid unnecessary and frequent pressing of the gas, as this can damage the engine.
- Do not drive over hard obstacles or try to break up the ice.
Once all work is completed, the snow blower is cleaned and stored in a dry place. This will prevent it from breaking.
How to make a snowmobile from a chainsaw
The snowmobile is manufactured according to one of 2 schemes:
- single-track (2 skis in front, 1 track in back);
- two-track (1 ski in front, 2 tracks in back).
Any snowmobile device has the following design:
- Engine.
- Supply system.
- Oil injection system.
- Transmission.
- Chassis.
- Steering.
- Frame.
- Electrical equipment.
Before you begin making a homemade snowmobile from a chainsaw and its further assembly, you need to design drawings of all working components and the general appearance of the vehicle. It is better to draw each assembly unit separately and take out the dimensions.
During the development process, the brand of gasoline tool is taken into account.
Models such as Druzhba, Ural and Shtil are well suited.
The Druzhba chain saw has a simple design. The disadvantage is the low motor power (1 kW) with a large mass of the tool (12 kg).
The Ural has a weight of 11.7 kg and an engine power of 3.68 kW.
- ability to work at low temperatures;
- high environmental friendliness.
When making a snowmobile from a chainsaw with your own hands, you can choose the Shtil brand. It is characterized by noiselessness during operation, a power of 1.5 kW, and has a nominal weight of only 3.9 kg.
The initial stage is the manufacture of the base of the frame structure from welded spars. For the middle part, corners 50x63 mm made of hardened steel are used, the front and rear are made of S2 steel with a flange at an angle of 90°. All elements must have holes of the same diameter for mounting with the track wheel and drive shaft. Brackets for road wheels are welded to the bottom of the frame.
The racks are made from 30x30 mm corners and connected by metal crossbars. The result should be a structure in the form of a small portal. A platform is required for the mounting location of the chain saw gearbox and the chain drive shaft. Sheet steel of the required size is selected, usually 2-3 mm thick, and welded to the center of the right side of the module and the portal.
At the back of the portal and at the same time in the middle of the module, a place is formed for the seat, which is subsequently made from boards and fabric or removed ready-made from old equipment, for example, a moped.
The front spar and the drive axle traverse are installed to the beam, which is a standard water pipe with a radius of 0.75 mm. Steering ski bushings are welded at both ends, and a stand for the engine subframe is welded in the center. The mounting points for the supports are reinforced with 2-mm metal gussets for strength and stability of the structure.
The mechanism from the Buran unit is used as a caterpillar, the belt is shortened by 0.75-1 m. The gears of the gear drive are planted on the transverse shafts, then the web is laid. The caterpillar gear is made from a nylon sheet measuring 15 mm.
Drive shaft
To make the drive shaft, a metal pipe with a diameter of 14 mm is taken, and flanges are installed on top to fix the wheel teeth. At the ends of the mechanism, pin tips are pressed in and welded with space provided for bearings.
The snowmobile engine is the most important component that affects the operation of all self-propelled equipment. Therefore, experts recommend using a power plant from a Shtil chainsaw with an engine power of 1.5-3 kW. The motor is mounted on a stable support of the cross beam. The gearbox is rotated 180°, fixed on the platform, and the intermediate shaft of the 2-speed transmission is also mounted. The fuel tank is installed on top.
The drive sprocket with an internal key made of St20 is attached to the shaft with an M12 nut and a spring washer. For precise fixation, a thread of the required parameter is cut on the tip. It is taken into account that the 1st transmission stage corresponds to a large sprocket with the maximum gear ratio (on the Ural engine there are 38 teeth), the 2nd stage corresponds to a small drive sprocket with 10 teeth.
The chains are of a standard type, with a pitch of about 16 mm.
Brake system
If the snowmobile is designed to travel at low speeds of up to 30 km/h, then the braking system may not be provided. Vehicles are stopped by friction in the chassis and transmission systems.
Steering
Control - steering on support-steering skis. The support arms are rigidly connected to the steering shaft bipod. The steering wheel is two-handed, with a gas handle mounted on the right side.
Snowmobile device
Homemade snowmobiles are built on caterpillar tracks. The tracks are driven by an internal combustion engine mounted on a rigid metal frame. They are supported in working position by wheels and special rollers. Main options:
- With a solid or fracture frame.
- With rigid or shock-absorbed suspension.
- With an engine from a walk-behind tractor or from a stroller.
Short skis are used for steering. Light snowmobiles (weighing up to 100 kg), designed to travel at a maximum speed of up to 15 km/h, do not necessarily require a braking system. They stop easily when engine speed drops. make a homemade snowmobile on tracks using the following algorithm:
- Selection of engine, calculation of frame and chassis.
- Frame assembly by spot welding.
- Steering device.
- Installing the engine in the design position on a temporary mount.
- Checking the structure for resistance to capsizing.
- If the test is successful, the frame is completely welded and the engine is installed.
- Installation of drive system, axles.
- Assembly and installation of tracks.
- Installation of body parts.
After this, final tests are carried out. If the snowmobile drives normally and does not tip over, then it is driven into the garage and disassembled. The frame is cleaned of rust, painted in 2 layers, the remaining elements are finished, and then a homemade snowmobile on tracks is assembled with your own hands.
Principle, device diagram, theory, how everything should work out
All work begins with a plan and drawings, which can then be relied upon. Diagrams and drawings will be required in order to take into account all the components and their location, the relationship between each other and the operation of the mechanism as a whole. Pay close attention to the location of each unit, as if you make a mistake, the snowmobile simply will not move.
Work plan:
- First, the chainsaw motor is attached to the made frame.
- Skis are installed in the steering part of the snow scooter, which are the main element of movement.
- Then the steering is installed.
- To set the mechanism in motion, it is necessary to install tracks at the rear.
- Connect the track disk and the chainsaw motor sprocket.
- Finally, the driver’s seat is installed, which is mounted on a specially equipped place.
To equip the steering on a snowmobile, borrow the handlebars from a moped or bicycle. The main task will be to properly secure the steering wheel so that when you turn, the skis also turn.

Model overview
Let's look at several popular children's gasoline models.
- Taiga RM "Lynx" . The first domestic unit of this type, designed for the smallest. This device will not carry more than 40 kg of load, and will not accelerate faster than 13 km/h. In fact, this is just a slightly improved sled, but at the same time very reliable, with a bunch of technical devices. The purchase will cost 80-90 thousand rubles.
- Yamaha SRX 120. Model from a manufacturer that has long established itself as an undisputed leader in the light motor vehicle industry. Everything here is done for the utmost convenience of the little driver - the mechanism is very easy to operate, has an automatic clutch, and even allows you to adjust the rear suspension. The quality and thoughtfulness of the unit are justifiably worth the 150 thousand rubles that are asked for it.
- SnowRunner Max 80. A budget snowcycle, the cost of which in domestic stores starts from a modest 40 thousand rubles. At a low price, it has a decent load capacity - up to 50 kg. According to the manufacturer, the unit is so easy to operate that it is suitable for drivers aged 4 years and older.
Chainsaw unit
Using this tool you can make a children's snow scooter. However, adults can also use a homemade snowmobile using a chainsaw. At the first stage, you need to decide on the type of tool. Its brand is not of fundamental importance if the power plant is working properly. To make a snowmobile from a chainsaw, in addition to the motor, you will need a gearbox.
To make a frame, you can take metal corners and two plates. First, the edges of the sheets are bent at an angle of 90 degrees, and then holes are drilled into them. A caterpillar shaft is mounted in the front part of the structure, and an axle for gear wheels is mounted in the rear part. Also, brackets should be welded to the bottom of the frame, parallel to each other.
An axle for 18 road wheels arranged in a checkerboard pattern is installed in the lower grooves. On the spar it is necessary to install 3 racks made from angle iron. To strengthen the structure, the racks are connected by transverse beams. A second sheet is attached to the front part, on which the intermediate shaft and gearbox will be placed. The next step is to make a subframe from metal pipes.
A flange is installed on the tubular drive shaft. Trunnions are welded at the end of the shaft, and the right one should be longer than the left one. The chain sprocket will then be mounted onto this extension. Since the snow scooter is not capable of reaching high speeds, you can do without a braking system.
Making a homemade snowmobile is quite possible, but you will have to make an effort. However, considering the cost difference with ready-made solutions, it is definitely worth it.
Purchased or homemade
A homemade snow scooter has many advantages over a purchased one. Firstly, it's its weight. For the structure to move smoothly in the snow, it must be as light as possible, because the driver’s weight will also need to be added to it. Purchased ?Husky? it will weigh about 80 kilograms. This weight is due to the gasoline-powered engine installed on the snow scooter. A homemade snow scooter can be made, as we discussed above, using electricity. It is cheaper, lighter, more convenient and environmentally friendly. On the other hand, there are children's models that can support one adult. The weight of this design does not exceed 20 kilograms.
Purchased ready-made models, if not made in China, are of better quality. After all, if you are not a master mechanic, then a homemade snowmobile can have various disadvantages? either they didn’t calculate the thrust star, and it quickly “slipped”, then the speed of the snow scooter suffers, and so on. But constructiveness and quality imply considerable costs. Please note the prices above, including the famous "Husky".
