Snowmobiles from a walk-behind tractor on wheels, manufacturing drawings. A snowmobile from a walk-behind tractor - how to make decent transport for the winter? Main stages of work

Give our man an engine - and he will make a walk-behind tractor, tractor, boat or homemade snowmobile. It all depends on the climate zone in which “Kulibin” lives. And since the territory where there is snow cover for almost half a year is quite vast in our country, the question “how to make a snowmobile” is quite relevant.

Homemade snowmobiles of last season - video review.

There are even models developed by folk craftsmen and then produced in small batches.

Important! All designs proposed in the material are not a means of transportation from the point of view of the Law. You can travel on them at your own peril and risk through deserted snow-covered expanses, and not at all on roads, including winter roads.

You can make a snowmobile with your own hands according to one of the concepts

On pneumatics

In essence, it is a mini-tractor with original wheels. Due to the large contact area with the surface, it overcomes even loose snow. It is usually made from a motorcycle or walk-behind tractor.

Important! Do not confuse this vehicle with floating all-terrain vehicles on similar wheels. Snowmobiles have a different ratio. total mass, and buoyancy of pneumatic wheels.

Classic design

With driving track and steering ski(s). The project has been proven over the years; the difficulty lies in the manufacture of the caterpillar itself. The vehicle turns out to be universal, easily moving on any roads, including rough terrain. In some cases, homemade products are superior to many industrial designs.

Using the Drive Wheel

In this case, wheels with lugs. A paddle steamer operates on this principle. The advantage of the design is the relative ease of manufacture. Disadvantage: insufficient adhesion to the surface of the propeller; slipping is possible on difficult terrain. Such models come out well from mopeds and motorcycles, giving a second life to the “donors”.

Snowmobile

The simplest from the point of view of implementation is a homemade snowmobile. It is enough to place the cart on the support skis and install the traction screw on any suitable motor. In addition to some difficulties associated with the manufacturing technique of the lead screw - more problems not in the building. The disadvantage is that this design moves only on a relatively flat surface. Another problem is that with low engine power, it is difficult to move against the wind.

By donor type or application various types engine, homemade snowmobiles are divided into the following types:

• Using a chainsaw motor. Low power does not allow moving on such vehicle heavy weight. Therefore, chainsaw snowmobiles are usually single-seaters;
• Moped or motorcycle. A fairly simple project to make. The engine is designed for a certain load, all that remains is to remake the driving element and replace front wheel to ski;
• Snowmobile made from a walk-behind tractor. The design is quite complex, but in terms of reliability it is practically not inferior to the factory one. The engine is designed for long-term operation under load; the kit includes a gearbox, which expands the capabilities of the vehicle. In addition, the power plant can be removed for the summer season, and the walk-behind tractor can be used for its intended purpose;
• DIY snowmobile based on a car or using a motor from passenger car. A fairly rare type of homemade product; its production requires professional equipment and complex engineering calculations. But snowmobiles made on the basis of cars are distinguished by high comfort, safety and reliability.

Walk-behind tractor - special equipment, intended for processing land plot. But if you want to expand its functionality or simply purchased another walk-behind tractor, then from old model You can easily make a walk-behind snowmobile! Firstly, it will cost you much less than industrial analogues. And secondly, the characteristics of such a home model will prove to be no less effective in operation. In addition, a snowmobile is one of the best vehicles in winter time year. It is quite maneuverable, economical and has good maneuverability. It is thanks to these properties that any industrial model A snowmobile is quite an expensive pleasure. But with the right tools, ingenuity and strong determination, you can easily make a snowmobile from a walk-behind tractor yourself!

Snowmobile from a walk-behind tractor - select the type

This is the first important decision you will have to make when implementing this task. Homemade snowmobiles from a walk-behind tractor can be made either on wheels or on tracks.

In the case of a wheeled version, special wheels are needed. In addition, you need to take care of the availability of a trailer. In fact, such a solution involves a minimum of changes in the design and will take much less time.

The caterpillar track is a more complex solution both in the structural part and in the functional part. In addition to the fact that you will have to assemble all the chassis your snowmobile, keep in mind that such a snowmobile walk-behind tractor will only retain the motor from the walk-behind tractor itself. Everything else will have to be sorted out and reassembled, not counting the fact that you will also have to make the frame and several small parts yourself. However, although the solution is complex, it is quite feasible. In addition, such a snowmobile has much higher cross-country ability and stability parameters than snowmobiles with wheels.

Wheel travel will perform well in regions with minimum thickness snow cover, in all other cases, the answer to the question of how to make a snowmobile from a walk-behind tractor assumes the presence of tracks instead of wheels.

Selecting a donor walk-behind tractor

A walk-behind tractor is suitable as a base not only due to its power, but also due to the fact that you can literally find it on everyone’s property. If you are going to make homemade snowmobiles from a walk-behind tractor on tracks, you only need a motor. In the spring, you will be able to put it back in place and use the walk-behind tractor for its intended purpose.

Any engines will do, but it is advisable to use at least a middle-class engine. In addition, a rear towbar must be available. Also you need the ability manual control. If the walk-behind tractor motor meets these requirements, there will be no problems with everything else. Many people prefer to use Japanese models.

In addition, such engines are air-cooled, which can be considered a plus for any snowmobile. Such a snowmobile made from a walk-behind tractor is capable of freely transporting several people, and even small loads, without interruption in operation.

For self-assembly snowmobile you will need:

1. Welding machine;
2. Engine from a walk-behind tractor;
3. Pipe bender

And also some other spare parts and components, depending on the features of the design you choose. The production itself will be carried out in several stages.

Let's move on to design

The first thing you should take care of is a quality drawing. You must clearly understand what exactly you want to do. Then the answer to the question of how to make a snowmobile from a walk-behind tractor will be really simple for you.

All designs of homemade snowmobiles can be divided into two large parts: driving and driven. The driven part includes shock absorbers, skids and a steering column. The leading part is the frame, drive and itself power unit. In addition, you should decide in advance which parts you can make and which parts you will have to buy in a specialized store.

For example, the frame is often made independently. Pipes are used for this. Even water pipes may be suitable, but pipes specifically from frames will work much better. For example, from a motorcycle frame. In order for the frame to take the required shape, you will need to bend the pipes with a pipe bender. The resulting structure is secured using a welding machine.

To avoid mistakes when making frames, you can use spot welding. After this, the entire structure is checked and fastened with a seam. At the final stage, brackets are welded to the frame to install all other parts.

Second stage of design

The second stage is the installation of the skids, engine and other parts. Skids are several wide skis that are attached to the steering column. After securing them, you can begin installing shock absorbers for the front suspension of your snowmobile (motorcycle shock absorbers are best suited). Install the engine and gearbox on the drive part. After this you can move on to the tracks.

You can also make snowmobile tracks with your own hands from scrap materials. The most important criterion: reliability. They must have good grip on the surface so that moving on a snowmobile does not cause any difficulties.

For production, you can use anything, from conveyor belts to water pipes. After the work is completed, you will receive a full-fledged snowmobile at minimal cost. Its average speed with a sufficiently powerful and serviceable engine will be from 60 kilometers per hour. But remember that when driving over rough terrain, the speed will change constantly. Initially test your snowmobile by riding it on the easiest sections without bumps or sharp turns. Only after this can you begin full-fledged work. You can even ride such a snowmobile through the forest, provided that the driving is sufficiently careful.

They started making snowmobiles out of walk-behind tractors a long time ago. Many craftsmen actively share their homemade products online. Of course, not everyone can afford buying a branded snowmobile. But to have your own snowmobile, it will be enough to put in a little effort and prepare parts, most of which can be found in many garages. The main necessary part in order to make a snowmobile from a walk-behind tractor with your own hands is, naturally, the walk-behind tractor itself.

Below is a detailed look at the DIY plan. The article presents a version of a snowmobile made on the basis of a Neva walk-behind tractor with a Japanese-made air-cooled engine. This unit has a power of 5-7 hp.

1 Selecting a walk-behind tractor model

Snowmobiles can be equipped with completely different walk-behind tractors. Some of those who independently assembled this winter type of transport even installed walk-behind tractors with 2-stroke engines on it. Reviews craftsmen They claim that the advantage of such motors is their .

It has become widespread in our country. Depending on the modification (there are 8 different models). Neva has gasoline engine power from 6.0 hp to 9.0 hp with four speeds switched by a chain gearbox. The volume of the fuel tank in each modification is also different and varies from 3 to 5 liters.

As you can see, the power of the Neva walk-behind tractor is perfect for conversion to a real snowmobile. The strength of such a machine will be enough to transport several people, in addition to a sufficient volume and weight of cargo. And the speed that this device can develop can reach 60-80 km/h.

2 Plan for converting a walk-behind tractor into a snowmobile

First of all, you need to think about what your future “monster” will look like and transfer your thoughts to a blank sheet of paper. If you have no problems with drawing, then your thoughts can be depicted in the form of drawings - this will be the best option, since the risk of making mistakes in calculations is reduced. It would also be a good idea to make a mock-up; you can use, for example, cardboard as a material.

In order to have a good idea of ​​your future model, we recommend that you familiarize yourself with the previously manufactured snowmobiles of other people. On the Internet you can find a lot of successful and not so successful prototypes, looking at which you will form your own vision of the future of winter transport.

Then make a list of the necessary parts and tools that will be useful to you in realizing your plans. Buy additional spare parts. Once you are sure that you have everything you need, you can proceed to the next step.

2.1 Assembly steps

In general, assembling a snowmobile from a walk-behind tractor can be divided into several stages. However, there is no universal plan, and everyone can do the work in the order in which they are most comfortable.

Most amateur designers act in the following sequence:

Frame making:

Strong pipes are prepared. Most suitable option– motorcycle frame;
the desired shape is created using a pipe bender;
spot welding pipes are connected.

Mounting parts:

All existing joints are closed with a continuous seam;
a bracket is welded to the frame, onto which the power unit (walk-behind tractor) is attached;
the walk-behind tractor itself is installed;
installation of the seat and other parts (runners, steering columns, shock absorbers, etc.).

Particular attention should be paid to the accuracy of calculating the dimensions of parts. This needs to be done so that you don’t end up having to disassemble and remake your brainchild due to an incorrectly measured length of a pipe, for example. The snowmobile attachment must be made strictly according to the selected drawing.

2.2 Features of assembling a snowmobile from a walk-behind tractor

One of the main features and problems that arise when assembling a snowmobile is the issue with.

Some craftsmen make tracks themselves. Those who cannot do this go to specialized retail outlets and buy ready-made factory products. You can often find a homemade snowmobile with half a Buran series track. In this case, the weight of the entire chassis, including the engine, is 20-30 kg.

The second most important feature is the implementation of the driven part of the snowmobile, which is attached to the walk-behind tractor. Almost anything that comes to mind can be used as space for passengers and luggage. For example, you can install an old chair or stool on the frame. You can even attach an ordinary sled to the walk-behind tractor; such options have also been noticed. Or you can equip the frame with several seats, and attach a sled to the back, which will act as a trunk.

The third feature is the skis. If you install a sled, you most likely will not have to bother with selecting the right size of ski tracks and their design. But, if you are going to make ski tracks with your own hands, we recommend that you pay attention that plastic skis will have poor adhesion to the snow surface, so the choice of material should be thoughtful. Also, do not be lazy to install undercuts from a metal rod on them. The optimal thickness of the rod is 8 mm in diameter.

It is also worth noting that the finished snowmobile that you made from a walk-behind tractor will be incomplete if it is not supplemented with shock absorbers. Although this is not the most important detail However, it is capable of improving ride quality and adding a little comfort. A good option here are shock absorbers that were previously installed on the frames of old motorcycles. But for the best effect, it is recommended to make a design that will allow the installation of new shock absorbers.

Despite the fact that no one obliges you to register a homemade snowmobile from a walk-behind tractor, the rule traffic Still worth following. At the very least, don't drive in drunk, don't go to maximum speeds and try to avoid dangerous crossings (for example, frozen bodies of water).

The most successful craftsmen assembled such home-made “beasts” that accelerated to 70 km, and some of them could even reach 80 km, but these were the cars of professionals. However, the average homemade snowmobile reaches a speed of 25-30 km/h.

2.4 Test drive a snowmobile from a walk-behind tractor (video)

A snowmobile is a unique vehicle for daily use in winter. It is used for movement through snowy areas during scientific expeditions, excursions, hikes, hunting animals, and protecting the territory. Such a product can be purchased at a specialized store or made with your own hands. If ready-made structures have a fairly high price, and not every person is able to afford such a purchase, then homemade ones are more affordable alternative option, made from scrap materials and equipment.

You can make a homemade snowmobile with your own hands using available equipment. For these purposes, experts recommend using:

• chainsaws;
• walk-behind tractors;
• motorcycles.

Important! To make a portable snowmobile at home, you must have skills in working with plumbing tools.

Drawings, options for finished work

The design of a snowmobile must begin by creating a drawing of the desired product. He will help in the process of making practical and functional equipment that will serve for many years.

If you can use ready-made drawings to create a snowmobile from a walk-behind tractor or a motorcycle, then for a design from a chainsaw they are not provided, since each tool has its own technical specifications and features.

Chainsaw snowmobile

Advice. The snowmobile can be made as either a tracked vehicle or a ski vehicle.

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 - the Druzhba, Ural and Shtil chainsaws (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:

1. Caterpillars.
2. Transmissions.
3. Engine.

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.

Advice. To give the necessary rigidity to the structure, the metal is bent at an angle of 90 degrees.

• Carefully make two through holes for placement of the track shaft and track wheel guides (tensioners are installed on both sides of the side members).

Important! Front device specifically designed to tension the second stage idler, 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).

Advice. In order not to waste time making rollers and axles for them, they can be borrowed from old equipment for digging up potatoes.

• 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 (for these purposes, use a suitable box or car seat), it is fixed in the area between the middle and back designs.

• 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.

Snowmobile from a walk-behind tractor

A walk-behind tractor is another option for equipment that is used in the process of making a snowmobile with your own hands. Its design practically does not need to be altered, since it is initially multifunctional.

There are three types of walk-behind snowmobiles:

• wheeled;
• on tracks;
• combined.

Before you start working with a walk-behind tractor, you need to decide on the type of future design. The complexity of the master’s work, as well as the duration of the entire process, will depend on it.

Construction of a snowmobile from a walk-behind tractor

Important! To create a wheeled snowmobile, you do not need to modify the steering system, special attention You only need to pay attention to the frame of the device and the skis.

• The snowmobile frame is made of metal pipes or angles (it should be rectangular in shape).
• A box or chair is attached to the finished base to accommodate the driver.
• Skis are made separately from angles and sheet metal and welded to the frame.
• The finished structure is attached to the walk-behind tractor and used for its intended purpose.

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.

Important! Motorcycles "Ural", "Izh" and "Dnepr" are the most suitable models for making a snowmobile with your own hands.

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.

• 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.

• Install a transmission, 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:

• longitudinal traction;
• lateral thrust.

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.

Homemade snowmobile: video

During cold weather, transport on two wheels becomes irrelevant, and sometimes it is impossible to drive through snowy expanses even by car. What to do in a situation where there is no money to buy a vehicle more adapted to the harsh winter?

In this case, you can make a homemade snowmobile. Winter vehicles are most often equipped with a tracked drive and steering skis are installed at the front. The snowmobile has high cross-country ability, light weight (70-80 kg), which allows it to drive both on valuable snow and on hard-packed snow-covered roads. Driving this vehicle is easy and the speed is low. So riding a snowmobile in the countryside in winter is not only convenient, but also safe.

Features of homemade snowmobiles

A huge number of companies sell snowmobiles in the CIS. But their prices are high even for families with decent incomes. If you don’t want to overpay for advertising and are a hardworking and creative person, then try making a homemade snowmobile.

A self-propelled gun made by yourself costs 7-10 times less than the cheapest factory-made models.

The success of making a snowmobile yourself depends on several factors:

• your personal skill;
• your engineering and design thinking;
• availability of parts and assemblies from other snowmobiles, motorcycles and other things.

It should be kept in mind that riding a snowmobile, like riding any vehicle, is associated with increased danger. Even though homemade devices, as a rule, are not capable of reaching speeds of more than 15 km/h, the quality of parts, welding, and bolting of elements should be approached with the utmost seriousness. The issue of operational safety and reliability of the final unit should be the main one for any person who intends to make a snowmobile with his own hands.

Preparation

Before you start making a snowmobile, you need to calculate the basic parameters of the device. If you are a bit of a design engineer, then it is appropriate to make a drawing of the unit. In principle, all snowmobiles are designed the same and simply. Your task is to make a reliable device modeled after all other variants of this class of vehicle.

What you will need for production:

1. Pipe for the frame, for pendants and other frame elements.

It was experimentally found that the optimal pipe diameter is 40 mm. If you are using a profile, then 25 x 25 mm will be enough. Wall thickness – 2 mm. With smaller parameters, the resistance of the device to deformation will be reduced. If they are large, the car will become heavier, which, accordingly, will affect the already not brilliant driving characteristics.

1. Wheels with rubber on the axle.

Wheels from ATVs (small models with a wheel diameter of 30-40 cm), some carts, etc. are suitable. A total of 2 axles with 2 wheels on each are required.

1. V-belts or conveyor belt.

The main element of the "caterpillars". The optimal thickness is 3 mm. This is enough for stability and wear resistance.

1. PVC pipes.

They are used to make lugs - the second element of the “caterpillars”. The optimal diameter is 40 mm with a wall thickness of 5 mm.

1. Propulsion system.

Typically, an engine, carburetor, fuel tank from a motorcycle.

1. Transmission mechanism.

As a rule, they use sprockets and a chain from a motorcycle, and sprockets from snowmobiles. Drive shaft from any unit, suitable in size.

1. Guide skis.

It is optimal to take skis from another snowmobile. Since this element must be as reliable as possible, designed for the load of the unit itself, plus the driver and possible passengers.

1. Steering wheel.

As a rule, they use a motorcycle handlebar, respectively, with a gas handle and a cable.

1. Platform, seat, body.

In principle, you can do without a platform by attaching the seat(s) and the body (optional) directly to the frame. But sometimes an additional platform is constructed on the frame, for example, from wooden boards, which provide slight cushioning, allow you to place several seats, and at the same time lightly weight the structure.

1. Shock absorbers.

This element adds additional complexity to the design. Therefore, they often do without it, especially if they plan to drive on uncompacted snow. Shock absorption is installed on the front suspension and driver's seat. You can take it from an old snowmobile or motorcycle.

1. Small details.

In addition to those listed above, other standard parts will be required to make a snowmobile: bolts, studs, nuts, hinges.

How to make: instructions

First, the frame is welded. Obviously, the larger the frame, the heavier the device will be and the slower it will move. The optimal frame length is 2 m plus/minus.

The following are sequentially fixed on the frame:

• drive shaft with receiving star;
• power plant with a transmission star and gas tank;
• front wheel axle (fixed fastening to the frame by welding or bolts);
• rear wheel axle (fixed with a movable guide element);
• front suspension with steering structure and guide ski(s);
• seat(s) and body.

Caterpillars are made of drive V-belts or conveyor belts. The optimal track width is from 40 to 50 cm. With a smaller width (40), the snowmobile will be more maneuverable and better controllable. With a higher value (50+), the patency of the device improves.

The function of lugs is performed by PVC pipes of the diameter indicated above, sawn in half lengthwise. They are attached to the rubber base using bolts and nuts. V-belts of insufficient width can be fastened to each other with metal grousers.

In order to be able to adjust the tension of the track, the rear wheel axle is attached using a movable guide element, which allows you to fix the position of the axle in a certain position.

Additional notes:

1. The center of gravity should be approximately the center of the structure. Since the power plant is mounted at the front, the driver's seat should be centered over the front axle or slightly offset to the rear.
2. Distance between drive shaft and power plant should be minimal to minimize losses of energy transmitted to the shaft.
3. If you install a shock absorber under the seat, then the front seat support is rigidly mounted on a profile arch, and the rear seat rests on the shock absorber.
4. If you are making a snowmobile with a heavy load in mind, then to remove some of the weight from the tracks, it is advisable to install an additional ski in the middle of the base (between two tracks). This ski, 50-70 cm long, is attached directly to the frame. However, this design requires a more accurate preliminary calculation with subsequent leveling of the height of the “leg”, which complicates the manufacture of the snowmobile.
5. It is advisable to maintain low pressure in snowmobile tires to avoid rapid wear of parts and high fuel consumption.

The considered version of the snowmobile is the simplest in design. If you have the tools and a welding machine, it can be assembled in the garage without any problems.
