Homemade mini wheeled snowmobiles. A snowmobile from a chainsaw with your own hands. Snowmobile from Motorcycle: A Craftsman's Guide

Making a snowmobile with your own hands is much easier than it seems. This will require desire, a few parts from equipment that is idle in a shed or garage, amateur skills in working with metal and a little time. Purchased units will most likely also be required, but the cost of a snowmobile or snow scooter with a motor, assembled in a few evenings, will be much cheaper than a purchased one.

General construction rules

Homemade products for driving on snow are varied in appearance, size, layout, power, and even in the principle of movement. But in each version there are nodes that provide the properties necessary for snowmobiles, namely:

1. Don't fall into the snow.
2. Move on the surface with minimal friction and in the desired direction.

Obviously, the probability of sinking into the snow and the friction force depend on the weight of the unit, the contact area, and the shape of the contact surface with the snow. Of course, the condition of the snow has its effect, but this must be taken into account.

To fulfill the main purpose, the following components are always present in the design of a snowmobile:

Making homemade products simplifies the availability of parts from specialized equipment. Spare parts from Buran snowmobiles or any tools and vehicles with a motor - scooters, motorcycles, motoblocks are often taken. The area for creativity when creating each node is huge. There are many varied and proven solutions for every detail.

Simple kids snowmobiles

The easiest way to make support is to fit wide skis under the frame. The option of creating snowmobiles is especially attractive in that a children's snow scooter and a tool with a low-power motor are used for their assembly - for example, a screwdriver, a hand-held lawn mower-trimmer or a 2-horsepower chainsaw.

A children's snowmobile from a chainsaw is assembled without reinforcing its frame, but for transporting adults in winter clothes, it is worth adding strength to the structure.

Ice snowmobiles

Walking along the river in winter is a slippery activity. However, if you replace the snow scooter with a sled and attach a 4-5 hp engine from the Druzhba chainsaw to them, you will get a safe means of transportation on ice:

The efficiency and speed of a sled on ice is much higher than that of other designs. But on loose snow, such a structure will go with great difficulty.

Inflatable wheels

In terms of time consumption, the second most attractive design after snow-scooters and sledges is a home-made snowmobile from a chainsaw on wide inflatable chambers from the wheels of a truck or tractor. For strength, a uniform layer of liquid rubber is applied to their surface or another flexible and waterproof material is glued. In a circle, at equal distance from each other across the chamber, chains are put on or cross-members are firmly attached to increase traction. Rims for wheels can be borrowed for bicycles, motorcycle or do it yourself.

If the inflatable structure does not have runners, then it will be able to ride even without snow on the soil. On such all-terrain vehicles, frames can be installed together with engines from Izh, Ural or Dnepr motorcycles. Design flaws - dimensions, weight and a high degree of wheel vulnerability, but this does not affect the popularity of high-speed home-made pneumatics.

Tracked

Caterpillar supports are used more often than others, while simultaneously performing the function of propellers. The reason is high efficiency and reliability. This design allows for high speeds while maintaining stability and maneuverability. There are several options for how to make tracks for a snowmobile with your own hands:

• from a conveyor belt;
• from truck tires;
• from drive V-belts.

Across the conveyor belt, it is necessary to bolt plastic or PVC pipes cut along the axis, no more than an inch in diameter.

Even a child can handle such a light apparatus.

Old truck tires with winter tread can also be used as tracks if the sidewalls are cut off. They do not need crossbeams, but they will have to sweep the edges with a line in increments of a centimeter, otherwise the tire will quickly get loose.

Drive belts, like the conveyor belt, must be equipped with lugs. Several parallel belts, from 2 or more, are interconnected with transverse strong lugs, attaching them to the belts with rivets or screws. The distance between adjacent hooks should be equal to the pitch of the drive sprocket.

Tracks made from conveyor belts or belts are often reinforced with a chain, which increases the reliability and durability of the mover.

These snowmobiles combine lightness with a reliable drive.

One of the varieties of tracked snowmobiles is a motorized dog, which is named after its resemblance to a sled dog. To the detriment of maneuverability, the design was lightened, the tractive effort also increased. But it is the most efficient snow towing mechanism.

To change direction, you need to apply considerable effort with a shift in the center of gravity of the motorized dog.

The basic dimensions for assembling a two-seater snowmobile shown in the drawing will help to make the ride comfortable. The rest of the dimensions will depend on the availability of spare parts, assembly diagram.

When driving, discomfort from headwinds is alleviated by installing motorcycle glass and mudguards for the legs. But it is impossible to completely close on such transport from the cold wind. Comfort requires a fully enclosed cab, which means more weight and a more powerful engine.

A snowmobile with a car engine is designed for long journeys over long distances. With the heat-insulating material of the body, the ride is comparable to the comfort of a car.

And the easiest way to achieve comfort is to simply put the rear-wheel drive car on wide supports such as skis, tracks or pneumatic wheel tubes, and also start up the drive of the standard wheels to the snowmobile propellers and attach the front ski to the steering bipod.

It will not be superfluous during manufacture to provide for a replaceable scheme for replacing wheels with skis and vice versa, if you use spare parts for alteration.

Upgrading homemade snowmobiles

Having a ride on a simple snowmobile assembled with your own hands, it is impossible to resist thinking about improving transport. First of all, you can reduce the influence of frosty wind. For this, ready-made fairings, windshields are usually used - for example, as in the popular Buran:

On short winter days, the light from a motorcycle or car headlight comes in handy more than once. To make the lamp shine, you need a generator. For mini-constructions, it is enough to install a bicycle generator driven by a motor reducer. High-speed vehicles will require more powerful lighting.

There is no limit to perfection. Once assembled, the snowmobile can be endlessly retrofitted with all new attachments for performance, comfort and reliability. Many forums on this topic exist on the network, allowing you to transfer your own and taking into account someone else's experience in designing winter transport.

Attention, only TODAY!

With the beginning of winter, especially snowy, there are problems with movement. Few people know that a snowmobile can be constructed from improvised means as an alternative means of transportation in winter conditions.

At the same time, there is no need for serious expenses. Moreover, in the presence of a large amount of snow on the car you will not go far, but the snowmobile will allow you to move in such conditions without any problems.

The assembly of any structure begins with the development of drawings. All the necessary units can be placed on them, after which you can proceed to the practical implementation of the idea. Therefore, at this stage, you should decide on which brand of chainsaw is suitable for the implementation of the plan.

Choosing a chainsaw

In retail outlets, you can find several models of chainsaws. The most popular of them are the Druzhba chainsaw, the Ural chainsaw and the Shtil chainsaw. Before choosing, you should think carefully, comparing their technical characteristics.

Chainsaw "Friendship"

This is the simplest chainsaw that can be used as a snowmobile engine. The result is an elementary construction without anything superfluous.

The only drawback is its high weight and relatively low power. In addition, there are no parts on the structure for securing the safety covers. In addition, this design is outdated in all respects.

Specifications:

• Power - 1 kW;
• Weight - 12 kg;
• Engine (two-stroke);
• Bus length - 45 cm;
• Fuel (gasoline).

Chainsaw "Ural"

This is a specialized model that has more reliability, power and less weight in relation to power. This is an environmentally friendly unit that can work in extreme conditions.

If you decide to use the Ural chainsaw, then this is a good choice. Its technical characteristics are fully consistent with those stated.

Specifications.

• Power - 3.68 kW;
• Weight - 11.7 kg;
• Engine (gasoline two-stroke);
• Overall dimensions - 46x88x46 cm;

Chainsaw "Calm"

It is also suitable for making a snowmobile with your own hands. This is an environmentally friendly device, absolutely harmless to humans. The main advantage of the chainsaw is its low weight and noiseless operation, in comparison with the Ural chainsaw, and even more so when compared with the Druzhba chainsaw.

Diagram of making a snowmobile from a Ural chainsaw with your own hands

Schemes for assembling a snowmobile from the Ural chainsaw: 1 - steering wheel; 2 - fuel tank (from the Druzhba chainsaw; 3 - power unit (from the Ural chainsaw); 4 - steering ski rack bushing (tube with a diameter of 30-2 pcs.); 5 - steering ski (2 pcs.); 6 - the drive cogwheel of the caterpillar (nylon, sheet s15, 2 pcs.); 7 - caterpillar (from the Buran snowmobile, shortened); 8 - frame; 9 - support roller (from potato sorting, 18 pcs.); 10 - brace backrest limiter (pipe ½); 11 - track tensioner (2 pcs.); 12 - track tension gear (nylon, sheet s15, 2 pcs.); 13 - bearing No. 80204 in the housing (4 pcs.); 14 - box-trunk, bottom-plywood s4, sides board s20); 15 - seat (cover-plywood s4, foam rubber, leatherette); 16 - 1st stage of the chain transmission; 17 - 2nd stage of the chain transmission; 18 - backrest-limiter of the seat (pipe ½ inch); 19 - driven sprocket of the 1st chain drive (large sprocket of the creeper, intermediate shaft); z = 38; 20 - leading sprocket of the 2nd stage of the chain drive (small sprocket of the creeper), z10; 21 - driven sprocket of the 2nd degree of the chain drive (drive sprocket of the drive shaft of the track), z18; 22 - leading sprocket of the 1st stage of the chain drive (sprocket of the gearbox output shaft), z12; 23 - steering knuckle lever; 24 - steering rod (2 pcs.); 25 - steering shaft with bipod; 26 - front axle beam (pipe with a diameter of 30); 27 - the drive shaft of the caterpillar; 28 - track tension axle.

Without creating a diagram and a drawing, it is unlikely that it will be possible to connect together the main structural units, such as:

• Engine;
• Transmission;
• Skis and tracks.

To simplify the design process, you should take the track from the Buran all-terrain vehicle. If a children's version is being designed, then skis will be enough.

Racks

Steering ski: 1 - runner (nylon, sheet s20, from a children's snow scooter); 2 - spring (normally stretched, from the rear shock absorber of the moped); 3 - support spring bearing; 4 - undercut (dural corner 20x20); 5 - spring cover (corner 35x35); 6 - fastening the spring to the cover (M8 bolt with washer); 7 - support arm (pipe 30x30); 8 - spring for fastening the rack - forks to the ski lever (steel, sheet s2); 9 - spring for attaching the support arm to the ski (steel, sheet s2); 10 - axles (bolt М8, 2 pcs.); 11 - steering knuckle rack (bicycle steering rack with crown and part of the fork); 12 - steering arm (steel, sheet s4); 13 - mounting the steering arm (type M16); 14 - fastening the spring center and the lever spring to the ski (M5 countersunk head bolt, 7 pcs.); 15 - lever sleeve (steel pipe with a diameter of 30 mm); 16 - sleeve bearing (nylon bushing, 2 pcs.); 17 - rack bushing (steel pipe with a diameter of 30 mm). In the top view, the parts 11, 12, 13 of the steering knuckle are conventionally not shown.

Snowmobile stands can be made of 3x3 cm corners. They are connected to each other with steel jumpers. As a result, there is a relatively small portal. To create a platform, you need to take a sheet with a thickness of 2 mm and connect it to the portal and the middle of the right side of the vehicle elements. This platform will serve as a place for attaching the chainsaw gearbox and the chain drive shaft.

A small space should be formed on the rear portal section and in the middle of the snowmobile for the seat structure.

The front of the frame and the front axle crosshead are connected by means of a beam. An ordinary water pipe with a diameter of 1.5 cm acts as a beam. At the end of this pipe, the sleeves of steering skis are attached by welding, and a stand is installed in the center. The strut will support the motor subframe.

Particular attention should be paid to the attachment points of the uprights. For greater reliability, the attachment points are reinforced with steel gussets, 2 mm thick. This approach will strengthen the vehicle and make it more reliable and durable.

Caterpillar

Snowmobile frame with tracked unit: 1 - the rear part of the spar (steel sheet s2, with flanges, 2 pcs.); 2 - tensioner (4 pcs.); 3 - rear portal (corner 30x30); 4 - the middle part of the spar (corner 50x63, 2 pcs.); 5 - bracket-fork for installing the axle of the support rollers (steel sheet s2, 10 pcs.); 6 - middle portal (corner 30x30); 7 - a platform for attaching the gearbox of the power unit and the intermediate shaft-creeper (steel sheet s2); 8 - kerchiefs (steel sheet s2, 4 pcs.); 9 - front portal (corner 30x30); 10 - the front part of the spar (steel sheet s2 with flanges); 11 - the axis of the tension gears; 12 - track tension cogwheel (2 pcs.); 13 - axle of track rollers (steel, circle 10, 5 pcs.); 14 - axle fastening (M10 nut and spring washer, 20 pcs.); 15 - spacer sleeve (duralumin pipe); 16 - skating rink (18 pcs.); 17 - bearing assembly (4 pcs.); 18 - drive cogwheel of the caterpillar (2 pcs.); 19 - the drive shaft of the caterpillar; 20 - drive sprocket of the drive shaft (driven sprocket of the 2nd degree of the chain drive), z = 18; 21 - steering ski steering knuckle bushing (tube with a diameter of 30 mm, 2 pcs.); 22 - front axle beam (pipe with a diameter of 30 mm); 23 - kerchiefs, 4 pcs .; 24 - sub-engine rack (pipe with a diameter of 30 mm); 25 - roller band (rubber ring, 18 pcs.).

To assemble a mini-version of a snowmobile, you can take tracks from the old Buran and modify it, shortening it by almost a whole meter. Gear wheels can be made from a sheet of nylon, 1.5 cm thick.

Drive shaft

Track drive shaft (idler shaft is the same, only item 4, replaced by item 1): 1 - left (along the way) tip (steel, cylinder 22); 2 - shaft (steel pipe 0.28x20; 3 - flange for attaching the gear wheel to the shaft (steel sheet s4, 2 pcs.); 4 - right (along the way) shaft tip (steel, cylinder 29); 5 - caterpillar drive gear (2 pcs.); 6 - frame side member, 2 pcs.); 7 - bearing housing cover (steel, 2 pcs.); 8 - bearing 80204 (2 pcs.); 9 - bearing housing (steel, 2 pcs.); 10 - drive shaft sprocket; 11 - fastening the sprocket to the shaft (M12 nut with wide and spring washers); 12 - key (steel 20); 13 - seal (felt, 2 pcs.); 14 - fastening the bearing housing to the spar (bolt M6, with a grover 4 sets); 15 - fastening the bearing housing to the side member (bolt M6 with a spring washer, 4 sets).

The drive shaft is made of a steel pipe with a diameter of 1.4 cm. Special flanges are attached to the shaft, to which gear wheels are attached. At the end of the drive shaft, by means of welding, trunnion tips are mounted. The pins must provide space for the bearings.

Engine

This unit is considered the most important snowmobile mechanism. Compared to other structural elements, such as a bar or chain, the engine must function properly and the snowmobile will not even move without it. Therefore, the long-term performance of the device will depend on the reliable and trouble-free operation of the engine. If you want to install an engine from an imported chainsaw, you can purchase a used "Calm".

Another important structural element, on which the trouble-free operation of the snowmobile depends, is the gearbox.

Asterisks

Immediately striking is the fact that the right hand piece has a keyway for mounting and securing the chain sprocket. This is the track shaft sprocket, which is securely fastened with a nut. To make the attachment possible, a corresponding thread is cut on the tip.

The end of the tension shaft has the same overall dimensions, and the fastening of the structural elements is carried out in the same way as the fastening of the track shaft sprocket.

The sprocket with the highest gear ratio (number of teeth) must be in the first gear stage. The engine of the Ural chainsaw has 38 teeth.

Steering

On a homemade device, you can install a handlebar of any design, and even from a bicycle. In this case, it is very important to bring manual control of engine speed to the steering wheel. In order not to bother too much, it is better to use a steering wheel from a moped, scooter, etc., where the engine power control mechanism is already provided. This will make the structure more reliable and easier to operate.

Brake system

Usually, such a vehicle does not have a braking system, and it is not necessary, since a snowmobile does not develop high speeds, especially a homemade one. Although, if you seriously approach this problem, you can build a primitive braking device.

Immediately it is worth noting that a self-made design, whatever it may be, is unlikely to be able to register (legalize) with the relevant authorities. And therefore:

1. According to the law, a homemade snowmobile does not belong to the category of vehicles. Therefore, its further application, as well as responsibility for the consequences, rest solely with the person who made it. It is better if it will be operated somewhere in the outback and not caught the eye of the relevant services.
2. A snowmobile and a floating all-terrain vehicle are completely different vehicles, although they have certain similarities.
3. Since the engine has a low power, it is not advisable to transport cargo with this vehicle. Better to move around on it alone.
4. For movement at night, lighting (headlights) can be installed on the snowmobile. This will increase the functionality of the device and comfort when moving.

Conclusion

Due to the fact that most people do not have the skills to make any structures on their own, they find that it is rather difficult to assemble a snowmobile with their own hands. And if it is possible to build something similar to a snowmobile, then it is unlikely to go, and if it does, it will stop very soon. And it will not look like a snowmobile at all, but a pile of spare parts assembled together. Fortunately, this is not the case, and with the proper approach and level of imagination, you can assemble a similar structure from improvised means, which are at least a dime a dozen in any garage. And if you have at least some experience with these spare and improvised materials, then the task is simplified altogether. Here the principle of desire already begins to operate and if it does not exist, then it is unlikely that it will be possible to collect anything at all, let alone a snowmobile.

The fact that the problem is urgent in our time is not just a statement, but a belief based on the problems of today. To our great regret, the state does not go to meet the broad strata of consumers, but has taken a course towards the production of only expensive equipment intended for sale to the consumer with money.

DIY snowmobile - Video

Have you decided to make a snowmobile yourself? There would be a desire ... Of course, to create a decent vehicle, you will also need locksmith skills, basic knowledge of physics, ingenuity, materials, spare parts and some tools. There is no doubt that you have all this, and what you don’t, can be acquired in the process. The main thing is what is the result! A self-made snowmobile that moves through the snow, overcomes snow-covered off-road terrain - it's cool!

Features and benefits of homemade snowmobiles

The design of the winter vehicle is based on a caterpillar drive and steering skis. Of all the advantages of homemade snowmobiles over factory models, the following can be distinguished:

• The price of motor vehicles assembled from scrap materials is 5-10 times lower.
• The ability to assemble a model of the desired configuration, power, etc.
• Reliability of construction, thanks to the use of quality materials and proven mechanisms.
• Benefit from the fact that you can not buy new materials and parts, but use those stored in the garage.

A homemade snowmobile is a vehicle that can be found not only on country roads and ski resorts, but also on the streets of settlements.

Snowmobile manufacturing according to drawings

How to make a snowmobile with your own hands, what parts and assemblies are needed? To create a homemade tracked vehicle for traveling on snow, a list of necessary components is drawn up, a sketch is made and drawings are made. In the future, they will serve as a guide for the creation of the vehicle.

The standard design consists of several elements. It includes:

• A frame that can be borrowed from an ATV, scooter, motor scooter, motorcycle, etc. If this is not possible, it is made by welding from thin-walled metal pipes, 40 mm in diameter.
• Seat - preferably made of moisture-repellent material.
• The engine can also be from a walk-behind tractor, motorcycle, scooter, etc. The choice is determined by the speed and weight of the vehicle.
• A tank, which is a container for 10-15 liters of metal or plastic.
• Skis for a homemade snowmobile on tracks can be taken ready-made or made from nine to ten-layer plywood, 3 mm thick.
• The steering wheel, like many other elements, is taken from a two-wheeled unit.
• A drive that transmits rotational movements from the engine to the track, which can be a motorcycle chain.
• The caterpillar is a complex component that requires detailed consideration.

How to make caterpillars with your own hands?

Homemade tracks can be made from car tires. The advantage of using tires is that they have a closed loop that reduces the chance of bursting. To make a caterpillar, the sides of the tires are cut off with a sharp boot knife. The lugs are attached to the remaining flexible canvas, which are plastic pipes, 5 mm thick and 40 mm in diameter, sawn to length. The halves of the pipes are cut to the width of the tire, bolted every 5-7 cm.

Tracks are made in a similar way from a conveyor belt. Its advantage is that in the case of its application there are no length restrictions. But there is a need for coupling by overlapping the ends of the tape with an overlap of 3-5 cm and fixing with bolts. When making tracks with your own hands, V-belts are often used. Connected by lugs, they represent a full-fledged caterpillar with ready-made cavities for the gears.

The wide track improves the flotation of the unit, but reduces its controllability. The factory models have three options:

• Standard - 15;
• Wide - 20;
• Extra wide - 24.

The sequence of creating a snowmobile with your own hands

To make a snowmobile on tracks with your own hands, you first need to connect the frame and steering gear. The height and angle of inclination are selected, then spot welding is performed. According to the drawing, the motor is installed and fixed. It must be ensured that there is no strong inclination. To avoid long fuel lines, place the tank close to the carburetor.

Next, the caterpillar is installed. The driven axle with the canvas is attached to the rear of the frame (depending on the design, on a suspension, fork, shock absorber, etc.)., The drive axle is attached in the middle of the snowmobile (usually under the driver's seat), closer to the engine. The gears of the axles are engaged in advance. After that, the fuel tank, throttle and brake cable are connected, the seat is mounted, and other work is carried out.

DIY snowmobile from a walk-behind tractor

Making a snowmobile from a walk-behind tractor is the most popular option. A vehicle intended for agricultural work can be used in whole or in part. It should be noted that the motors of walk-behind tractors, as a rule, are calculated for the weight and pressure of the wheels, which are several times less than the tracked one. For this reason, it is best to equip the snowmobile with low pressure wheels. This will help to avoid excessive fuel consumption and premature wear of parts. How a walk-behind tractor is converted into a homemade snowmobile, watch the video.

itemprop = "video">

When making a snowmobile, you must heed the advice of experienced craftsmen:

When cutting a pipe with a circular saw, it is recommended to cut one side and then the other. So you will be able to get even workpieces. It is better to pre-cut the pipe into pieces of the required length, since when cutting long workpieces, the plastic will melt, and the saw blade can clamp.

You can choose the size of the track as you like. It can be wide and short, narrow and long, but it should be borne in mind that the handling of the vehicle will depend on its width. A vehicle with a wide track is more difficult to control and the load on the engine will increase. A small caterpillar will sink in deep loose snow.

So that the equipment does not stand idle in the winter, you can make a snowmobile from a walk-behind tractor with your own hands. With minimal tooling skills, this is not difficult at all. Reverse alteration at the end of the cold weather will not take much time. This will allow you to use the walk-behind tractor for household work all year round.

Engine selection

The power unit must have a towing hitch with a manual control system. You can use a motor from the Neva walk-behind tractor.

On its basis, you can make a snowmobile for transporting goods and transporting 1 or 2 passengers. The power of such a device will be 6-7 horsepower. A snowmobile attachment to the walk-behind tractor will help increase the carrying capacity.

The main advantages of such a device:

• affordable price;
• power unit made in Japan;
• 4-stroke 1-cylinder engine;
• air cooling system;
• the ability to use gasoline as fuel.

Motoblock Neva has 8 modifications. Possible power ranges from 6 to 8 horsepower. There is a chain changeover gear for 4 possible speeds. The fuel tank, depending on the specific model, has a volume of 3 to 5 liters. The engine power will allow you to transport several people and cargo.

Nuances of construction

The main structural elements of a snowmobile are driven and driven parts. The driven part includes shock absorbers, a steering column, runners.

The main components of the driving part are the power unit, frame, drive.

Basic diagrams and drawings can be found in special literature. Based on the finished project, it is necessary to make a sketch and a cardboard model of the future device. Initially, you should decide on the options for using the snowmobile. This will help to correct the drawing and determine the items that need to be purchased, as well as those that you can make yourself.

The gearbox and engine must be installed on the leading part of the future snowmobile. First, you need to determine on which course the finished device will move - tracked or wheeled. Both options have their pros and cons.

A wheeled or tracked snowmobile

The easiest way to make a snowmobile from a walk-behind tractor is wheeled. To do this, you only need special wheels and (if desired) a small trailer. A wheeled snowmobile is more maneuverable. Rear mounted wheels have a relatively low specific weight. To prevent the unit from slipping on loose snow, you will need to additionally install special chains.

Snowmobile wheels can be made from truck cameras. In a deflated form, they are put on the wheels of the walk-behind tractor and wrapped in chains, the ends of which must be fixed, the chambers are pumped up with a pump.

Another option is to put metal hoops on the wheels of the walk-behind tractor and the trailer, 1 for each wheel. The required dimensions are determined by the size of the wheels. The diameter of the hoop should be slightly smaller and the width 2-3 times larger than that of the wheels.

To improve traction and stability of the snowmobile on the hoops (from the back), you need to weld 5 or 6 metal plates. The required thickness is 25 mm. The result is an imitation of lugs. You need to put on the prepared hoops on the deflated chambers, which, after inflation, will tightly press against them.

A tracked snowmobile is a more complex device. In fact, this is a snowmobile track attachment for a walk-behind tractor, powered by the main motor. Such homemade products are stable, reliable, with high traffic. In regions with abundant snow cover, such a snowmobile will be simply irreplaceable in the winter.

Do-it-yourself tracks for a walk-behind tractor are easy to make. To do this, you can use such materials at hand, such as:

• water pipes;
• motorcycle chains;
• conveyor belts.

In order for the tape on the tracks to remain in working condition longer, its edges must first be stitched with fishing line. Stitches should be made every 10 mm. To close the tape into a ring, you need to carefully sew the edges.

The tracked snowmobile will not slip even in very deep and loose snow. However, with high cross-country ability, its maneuverability will be noticeably lower, because the walk-behind tractor on tracks is much heavier. The undercarriage weight of the tracked snowmobile will be up to 30 kg.

Preparatory work

A homemade snowmobile from a walk-behind tractor can be used for chores, hiking, sports activities. Once the use case has been identified, the basic schema will need to be slightly tweaked.

To make a snowmobile from a walk-behind tractor with your own hands, you need to prepare the following tools and materials:

• apparatus for manual welding;
• special mask and gloves;
• grinder;
• hacksaw for metal;
• set of files;
• pipe bender;
• frame pipes, for example, from a motorcycle;
• brackets, clamps and other fasteners;
• small parts;
• motor.

To save money, many parts and parts for a snowmobile can be made by yourself or you can use parts from other equipment. When deciding how to make a snowmobile from a walk-behind tractor, you can use the advice of friends who have similar experience, special literature. Ready-made diagrams, drawings, photographs and videos will allow you to better imagine the design of the snowmobile and the main points of its creation.

The main stages of work

First you need to make the shape. For this, frame or water pipes are bent with a pipe bender in the desired version. Spot welding is used for the pre-connection. This will allow you to identify and eliminate the mistakes made.

Finally, you need to close the joints with an inseparable single seam. Weld the brackets to the finished frame. Installed on them:

• power engine;
• runners;
• steering horse;
• seat.

An old furniture chair or chair can be adapted to fit the snowmobile seat. Another option is to remove the finished seat from the old motorcycle. If desired, you can make 2 or 3 seats.

Comfortable steering for a snowmobile comes from an old bicycle, moped and other equipment. You can make a steering wheel yourself from a piece of bent pipe.

Trailer attachment and additional elements

A two-wheel single-axle walk-behind tractor can be made 4-wheel and 2-axle using a small trailer. It must be tightly welded to the walk-behind tractor frame.

First, a metal bar about 0.5 m long must be welded to the end of the drawbar. It is attached at the junction point of the trailer and the walk-behind tractor parallel to the main axis.

Having retreated from the edge by 6 cm, 1 hole is drilled on each side of the bar. Additional fastening will be provided by metal clamps, they must be thrown over the axis of the walk-behind tractor and fastened with bolts and locknuts, to which the cross is pre-welded. In this case, the bolt is passed through the holes in the crosspiece and in the clamp.

Such a complex fastening will be a reliable lock for the trailer and the entire structure as a whole. This will reduce the maneuverability of the snowmobile but increase its stability.

An old but still strong sled can be used as a place for passengers. It is easy to attach them to the walk-behind tractor with your own hands. For transporting luggage, the sled can be attached to the rear of the welded frame.

It is better to use wooden skis for snowmobile runners. In plastic, the grip is noticeably worse. They are attached to the steering column with special hinges. It is necessary to install undercuts on the skis. To do this, you can use a metal rod with a cross section of 8 mm.

Shock absorbers must be installed on the snowmobile - this will provide comfort while riding. Which shock absorbers will be installed (new or removed from the old motorcycle) must be determined in advance. You can install the linkage from the motorcycle. This will allow you to make the correct design.

Safety engineering

The finished snowmobile must first be tested on level ground. Passengers and cargo can only be transported after successful tests. A snowmobile is a vehicle. It can move at a speed of up to 70 km / h, so the basic rules of movement must be followed in order not to get into an accident.

Use extreme caution when driving in unfamiliar open spaces or in the forest, especially on freshly fallen snow. In this case, you should not develop high speeds. The best option is no more than 30 km / h.

When preparing for a snowmobile ride, you must wear a safety helmet and special suit. It is better not to use ordinary quilted jacket and felt boots. It is very dangerous to ride a makeshift snowmobile in ice-covered bodies of water. It is very dangerous even if the homemade device is in good order.

The walk-behind tractor is a professional tool that is used when carrying out agricultural work. A lot can be made using such equipment, this also applies to a snowmobile, the main thing in this is to be careful and observe the technology of work. A snowmobile can be performed if you prepare some materials and tools, a list of which will be presented below.

Such equipment can be used in winter as a means of transportation when it becomes necessary to go for firewood or hunting. The snowmobile has excellent cross-country ability and maneuverability, which are its main features. You can do a snowmobile from a walk-behind tractor with your own hands, while the reworking process will not be too easy, but it is still possible to carry out these works. You can choose one of the existing methods of carrying out these works, some of them are quite simple, while others are more complex.

Preparatory work

To carry out the work, you will need to stock up on a pipe bender. Such a tool is not always in the arsenal of a home craftsman, which is why it can be rented. It will be impossible to make a snowmobile from a walk-behind tractor with your own hands without using a welding machine, which is why, before starting work, you need to objectively assess your abilities. A walk-behind tractor will act as the main structural element; a manual control tool is perfect for this.

You should not look for equipment of a modern type, you will need to prepare something that belongs to the middle class. For the manufacture of a snowmobile, you will need tracks, which will act as a transport belt equipped with snow hooks. Caterpillars can be easily done independently, while you can be guided by your own imagination. A do-it-yourself snowmobile from a walk-behind tractor can be made without tracks, then you need to prepare the wheels.

Features of making a snowmobile

It is necessary to carry out the work according to a certain technology, which involves several stages. Initially, a sketch must be prepared, which will allow the assembly to be carried out correctly. It's good if you can make a mockup. It is important to correctly identify the design features of the equipment, which will depend on the tasks of the snowmobile. The model can be made of cardboard; it is preferable to make it in full size.

Features of the manufacture of the frame

Before you make a snowmobile from a walk-behind tractor, you need to think about which structural elements can be purchased and which should be made independently. At the next stage of the work, you can start making the frame. For this, pipes are usually used, it is preferable to use frame elements that were borrowed from a motorcycle. This is due to the fact that these components of the vehicle are the most reliable when compared with pipes, which are designed for

When making a snowmobile from a walk-behind tractor with your own hands, a photo of which is presented in the article, you will use a pipe bender that will allow you to form elements of the desired shape. Their fastening should be done using spot welding. Now you need to weld the joints in such a way that you get a continuous seam.

In advance, the brackets must be strengthened to the frame by using a welding machine, which will be needed to install the motor, seat, and other parts. Before you make a snowmobile from a walk-behind tractor, you need to prepare the seats, which can be ordinary old chairs. You need to borrow a handlebar from an old bicycle, which will also come in handy when carrying out work.

Ultimately, you should have a superb motorized vehicle that can fit one or two passengers. In addition, the structure will be able to carry a load of insignificant weight.

After it is completed from the walk-behind tractor, you can start using it. However, it must be remembered that safety precautions have to be observed, this will prevent injury. Thus, it is impossible to cross frozen bodies of water with this vehicle.

Alternative snowmobile making

A homemade snowmobile from a walk-behind tractor can also be made using a slightly different technology, while you will have to use a motor borrowed from the mentioned equipment. Before assembly, it is preferable to prepare the Neva walk-behind tractor, which has a Japanese motor. In the overwhelming majority of cases, the equipment includes a four-stroke gasoline single-cylinder engine, which is air-cooled. However, two-stroke motors can also be used, as they are lightweight. If you make a vehicle using such a motor, then you will get a structure that is perfectly repairable and can be started manually.

Snowmobile features

A snowmobile from a walk-behind tractor will be able to accelerate to 70 kilometers per hour. However, in this case, the assembly work should be approached professionally. This will create a snowmobile that will be able to overcome snow jams. On such a unit it will be possible to plow the land, go to the forest, go hunting or fishing, or just ride. Fuel will be consumed in a small amount, thus approximately 2 liters per hour will be consumed.

It is preferable to carry out a snowmobile from a walk-behind tractor according to a scheme that assumes the presence of two skis (they will be located in the front), as well as one caterpillar - in the back. This design has higher stability.

Another option for making a snowmobile

First, you will need to take the main components of the future design. Next, the motor is mounted on two rods, it will be necessary to fix it to the tracked motor. The rods must be attached to the crossbeam as well as the handlebars and skis. Between the rods, the seat, as well as the front pillar, should be mounted. When making a snowmobile from a walk-behind tractor with your own hands, the drawings of which should certainly be studied before starting work, it is necessary to use pins and bolts that will strengthen all the parts of the unit. This assumes the snowmobile is ready.
