How to make a snowmobile from a power tiller with your own hands
The basics of creating all-terrain vehicles on the basis of a power tiller
The question of how to make a rover from a power tiller with their own hands, is very relevant for farmers and even owners of small plots. This technique is an assistant for all occasions, since it is very easy to attach additional equipment, which makes a motocultivator as functional as possible. Traditionally, such equipment is used on garden plots and vegetable gardens. The tiller usually has a lot of work to do, as it can plow land, collect leaves and make hay. But for a certain period of time the technique stands idle. For this period you can occupy it with other works. For example, it is possible to make an all-terrain vehicle out of it. It takes just a little effort to turn a farming machine into a universal snow and marsh buggy. At the same time it is very easy to work with some machines. There are models that are modified by the attachment. This option is as easy to use as possible.
It is more convenient to make a cross-country vehicle from a Neva motoblock. The peculiarity of this equipment is that the manufacturer allows you to install a universal attachment on it. This makes it possible to modify the power tiller as quickly as possible. Thus, a marshmobile from a power tiller can be made in a matter of minutes. However, in order to transform the farming equipment, an all-terrain attachment to the tiller should be on hand.
Manufacturers offer a variety of additional equipment for this type of equipment. But such attachments are not cheap. Those who are not ready to spend thousands to turn a motor block into a cross-country vehicle, you can try to make equipment with your own hands. There are no special difficulties here, but some skills are still needed. First of all, the master needs to understand the technique and be able to work with a welding machine.
Homemade snowmobiles are built on the tracked course. The tracks are powered by a combustion engine mounted on a rigid metal frame. Supported in the working position by wheels and special rollers. The main variants of design:
Short skis are used for steering. Lightweight snowmobiles (weighing up to 100 kg), designed to travel at a maximum speed of 15 km / h, do not require the mandatory equipment of the braking system. They are easy to stop when the engine speed drops. Make a homemade snowmobile on tracks by the algorithm:
- Selecting the engine, frame and running gear calculation.
- Frame assembly by spot welding.
- Steering device.
- Installing the engine in its designed position on the temporary mount.
- Checking structure for tilt resistance.
- If the inspection is successful, the frame is welded, and the engine is installed.
- Installation of drive system, axles.
- Assembly and installation of the tracks.
- Assembly of the body parts.
After that do the final tests. 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 assemble with their own hands makeshift snowmobile on tracks.

A snowmobile is a multi-purpose professional mobile tool for agricultural work.
You can do a lot from a power tiller, even a snowmobile, the main thing is ingenuity. Such a construction will be a useful vehicle, not only in winter.
Snowmobile is an unusual winter transport. Excellent flotation and maneuverability. its main features. By types snowmobiles can be working, sports, touring and mountain
The process of converting a power tiller into a snowmobile is a complex process and not simple, but real.
There are many ways to remake a power tiller into a snowmobile, and the designs can be varied as simple or complex. It all depends on what purpose you need the snowmobile for.
But how to convert a single axle tractor into a snowmobile that the assembly was as reliable as possible? This will be discussed in this article.
Converting a power tiller into a snowmobile
Let’s start with the question. Why a single-axle tractor?? It is very easy to explain. Autumn has come and gradually all the field work came to naught. Single axle tractor, like a bear sent into hibernation. Until the spring it is clearly not needed, but no. In winter it can serve the owner faithfully, too, facilitating his labor activity. Helps in delivering firewood from the woods, water from the river, and simply makes it easier to move through the snow cover. Makes it fast and comfortable.
Where do we start?? With the engine. As a base unit for our snowmobile is well suited single-axis tractor middle class “Neva”, equipped with a rear coupling device and manual control. His engine at a fairly low cost, assembled from quality parts made in Japan. In addition, it is equipped with forced air cooling, which is very useful for the future snowmobile. As a result, we get a unit with a capacity of up to 7 liters.с.
For independent creation of a snowmobile you will need a pipe bender, a welding machine, an angle grinder, a power unit and a number of purchased spare parts that will be needed during assembly.
Snowmobile based on the power tiller: assembly
Assembly of the snowmobile on the basis of a motor block should be done in stages:
The design features of the device will depend on the projected tasks. The mechanism itself will consist of a driven part and a driven part. Slave part. it’s shock absorbers, skids, steering column. The master includes the frame, drive and motor. In order to intelligently pick up the details of the snowmobile better make a model (out of cardboard, for example) projected snowmobile, and it is better if it will be in full size.
It is necessary to determine the location and shape of all components of the future unit, the assembly of which is going to do with his hands.
Making a frame. It is necessary to initially make drawings, where you specify all the dimensions of the frame. For convenience, you can use the typical drawing of the snowmobile presented above. For this purpose it is possible to apply a pipe, preferably a pipe 25×25 as it is more reliable, than, for example, water pipe. Thanks to the pipe bender make the desired shape of pipes, secured by spot welding.
We weld the joints with indissoluble seam, to the resulting frame we weld brackets for fixing the engine, seat and steering column. You can use, for example, old armchairs as seats. Handlebar from a bicycle is useful.
As skids we use two skis, connected by hinges to the steering column. Use bolts as turning bushings. With regular lubrication they will last a very long time. In addition, thanks to the position of the pipes can change the clearance of the snowmobile. To relieve the track is installed supporting ski with tension rollers.
Assemble engine and gearbox on the drive part of the mechanism.
Determining the ride of your future snowmobile. It can be wheeled and tracked. In the first case, due to the low weight of the chassis, maneuverability is increased, but the cross-country ability decreases, especially in the loose snow. Therefore it is expedient to equip snowmobile wheels with chains. In the second case, on the contrary, the tracks increase cross-country capability, but reduce maneuverability.
To provide your machine with winter “shoes” is not so, simply. To reduce slippage use chains. Take a truck camera, deflate and put 5-6 chains on each wheel, then inflate again. As a result you get wheels adapted to winter conditions.
Another low-budget option wheels for the snowmobile.
As another option of winter wheels can be used tires of large diameter from trucks and tractors, pre-electric jigsaw cutouts, as shown in the photo to increase traction with the road surface.
Make four steel hoops with a diameter slightly smaller than the inflated chamber respectively all the wheels of the snowmobile. In width they should be 2-3 times larger than the corresponding wheel. Next, on the outside, weld 7-8 plates with a thickness of 20 mm for better traction with the roadbed. After that, lower the cameras, install the hoops and re-inflate. You will get an inexpensive, but fairly acceptable version of the wheel for the snow road.
The tracks for the snowmobile can be made at home with your own hands. As the material is suitable conveyor belt with bolted bars or pieces of pipe to increase traction with the road.
The frame is made of a square tube 25x25x2, it is equipped with a track, an engine with a gearbox, front suspension and a platform.
Consider step by step how to make different types of snowmobiles with your own hands.
Snowmobile from a snowmobile on wheels
To turn a motor block on wheels into a snowmobile you will need to take:
An indispensable condition of the whole idea. the trailer must be rigidly coupled with the snowmobile frame. Metal channel with a length of about half a meter should be welded parallel to the axis of the snowmobile. For this purpose, two holes are drilled on the edges of the channel. Perforated clamps around the edges provide extra anchorage and rigidity. They are attached to the snowmobile axle with bolts with a locknut, with a cross member welded to the structure.
This mount will become a stopper, fixing the trailer, preventing it from shifting at an angle. Such an element reduces the ability to maneuver the snowmobile, but makes it more stable. Thereby easily converting a two-wheeled machine on one axle into a stable four-wheeled vehicle. It doesn’t need any schemes and drawings, nor any additional costs.
A snowcat with a motor also requires the right selection of wheels. The easiest option is to buy them from a retailer for winter use, but looking for easy ways is not always advisable. The more economical solution would be to make the wheels yourself. A budget option is to equip the snowmobile module with cams designed for trucks. Dropped tubes are put on each wheel and fastened over the chain for driving on snow and ice. One is not enough, you need five pieces. Inflated camera in a round of chains will look like an ellipse with a surface divided into segments, like a daisy.
Another option of applying ingenuity and saving the family budget is to use metal hoops on top of the cameras. They should be wide enough, wider than the snowmobile wheels by a factor of two. The diameter of the hoop should match the inflated wheels on the power harvester and trailer. On the inner side of each hoop is welded a few metal plates. The thickness of the plates should be about 2-3 cm. After letting the tubes down, it is necessary to put hoops on the wheels of the snowmobile and then pump them up again. The inflated chambers will be pressed as much as possible against the metal circles. Plates like dirt hooks will help reinforce the grip on the snowy road.
Snowmobile from a power tiller on tracks
A single-axle caterpillar tractor is slightly more difficult to convert into a snowmobile, but possible. Using the motor of a motor block, you can make a construction with great stability and passability. To do this, mount the frame and transmission. Make sure you have enough engine power, you will need a single axle tractor with at least 6 horsepower. To make a snowmobile motonart with a motor you need to use:
It’s good if you have tracks from other snowmobiles in your home stocks. If not, you should not give up. To assemble the tracks yourself is quite realistic, using improvised tools and materials.
Next, you need to decide on the place of installation of the engine: in the front or in the back. Try to make the construction as light as possible, and the ski suspension. soft. All this will allow you to achieve high cross-country ability in deep snow. The principle is this: inside the caterpillar, 4 wheels roll on a conveyor belt when moving. Special pads are fastened to the tracks for improved traction. Tracks can be made to your own specifications, but think carefully about dimensions.
The tracks are wide or too long to carry unnecessary weight on the engine. Which, in turn, will make it difficult to steer the snow on the caterpillars. Too small a track would not be able to support the weight of the whole structure with a driver. It will become unstable and will fail in loose and deep snow. The tracks are made from the simplest materials: plastic or plastic pipes of small diameter, wheels, bearings.
0.5 cm long pieces are made of pipe, from which the chocks are obtained. They are attached to the tape at the same distance from each other. Then they are bolted to the holes in the transport belt. The frame is made using square tubes or channel bars. Use a steering rod without ball joints, because the axes of the steering and ski lie in the same plane.
Sleeves are mounted on the front part of the frame to enable turning of the skis. They can be made from steel sockets with small-diameter threads. Ski poles and steering rods are welded to the pipes. To control the snowmobile skis are attached to the corners with a metal undercut, which will allow you to move on the ice or snowpack.
The weight of such a snowmobile is no more than 100 kg, and to manage the vehicle is very simple. Since the engine power is small, the speed does not exceed 10-15 km / h, so the brakes are not provided. The end of the movement is due to the reset engine speed or the so-called engine brake.
Skids and engine
Wide skis are used as runners, which are attached to the steering column by means of a hinge joint. For front suspension use shock absorbers from a motorcycle.
The engine is installed on the driving part of the homemade snowmobile. In this case, before installing the engine it is necessary to decide what to use. the wheels or the tracks. Each of these options has advantages and disadvantages.
If the wheels are installed, the all-terrain vehicle from a power tiller will be more maneuverable. If you make tracks, the passability of the snowmobile increases, but it becomes more heavy.
The main elements of construction of the snowmobile are slave and drive part. The driven part includes shock absorbers, steering column, skids.
The main components of the leading part are the power unit, the frame, the drive.
The basic diagrams and drawings can be found in special literature. On the basis of the finished project it is necessary to make a sketch and a cardboard model of the future device. Initially it is necessary to determine the options for the use of the snowmobile. This will help to correct the drawing and determine the elements that need to be purchased, as well as those that can be made by hand.
Gearbox and engine should be installed on the drive part of the future snowmobile. Beforehand, it is necessary to determine on what move the finished device will move. crawler or wheeled. Both variants have their advantages and disadvantages.

The caterpillar snowmobile from a power tiller: the process of making it at home
The snowmobile, the drawing of which is shown below, is based on the motor of the cultivator “Neva”. Its production begins with a frame.
Frame for a snowmobile with your own hands
The frame is made of metal pipes with a diameter that is used for motorcycle frames. Water pipes are also suitable. To give the desired shape, a pipe bender is used.
To simplify the task and reduce design time, we suggest using ready-made drawings.
Designations according to the drawing:
- Toothed sprocket of the intermediate shaft;
- The intermediate shaft;
- sprocket with teeth;
- gear parts;
- driving elements of the caterpillar;
- caterpillar shaft;
- ski support poles;
- tensioning rollers for the tracks;
- the axle for tensioning the rollers;
- drum flanges;
- steering rack.
After welding the frame elements according to the established dimensions in its front part make a subframe. on it the motor is localized. A stand is welded with holes for it. The same holes must also be in the crosshead. These slots make it easy to tension the drive chain and adjust the position of the pulling unit.
In order to ensure that the unit can be started with the crank, the underframe is moved to the rear of the machine. An invaluable bonus will be to equip the original motoblock with the forced cooling function. This will reduce wear and tear on the carburetor and traction mechanism.
Intermediate shaft for a snowmobile from a power tiller
The diagram shows a general view of the intermediate shaft.
The numbers in the figure are marked:
- support part for the operator’s seat;
- Crossmember. is made from stainless tube 28 x 28;
- rack axle. of 18 x 18 tubes;
- crossbar. made of metal angle with the side not less than 25 mm;
- strut. a steel billet 0,4 x 0,05 m is taken as it;
- bearings 04;
- shaft (on the basis of a pipe);
- Toothed sprocket (as element 10);
- rubber cover.
All these parts can be made by your own hands.
making steering column for snowmobile: basic drawing with dimensions
Properly assembled and adjusted steering column. a prerequisite for the passability of the snowmobile from a power tiller on deep snow and smoothly overcome the rough terrain.
According to our proposed scheme, the steering unit consists of:
- frame crossbeam;
- steel rack in tubular design;
- steering support made of angle;
- a shaft adapted from a stainless steel pipe;
- washer made of bronze;
- M10 type nut.
After connecting them, let’s move on to the track part of the snowmobile.
Tracks for a snowmobile based on a power tiller
The tracked snowmobile attachment is made by hand using one of the suggested options:
For a light snowmobile, you can limit yourself to an ordinary conveyor belt, to which you adapt the roller chain.
- wrench ties;
- star element;
- track drive;
- rack and pinion track;
- homemade spar;
- slave mechanism;
- suspension for the skis;
- bolt, like the 12 and 13;
- guide rail;
- support shoe;
- fastener for the bearing;
- roller axle.
They are reinforced with spars, additional springs and are equipped with a lever to pull the snowmobile in case it gets stuck.
After the base blocks are prepared, move on to the assembly stage.
How to make a homemade snowmobile from a power tiller on tracks
Four wheels are mounted inside the track. When the movement occurs they roll on the conveyor belt, with fixed grousers. The track is driven by the chain from the motor, special drive sprockets, through the driven shaft. They are taken off the Buran.
The engine is taken from an ordinary power tiller, which has a capacity of 6 liters.с. You can’t make a fast speed on it. The soft suspension on the ski and track were removed, because the snowmobile is meant to ride on loose snow. This simplifies the design and reduces the weight of the snowmobile.
Making snowmobile tracks
Consider the process of making a caterpillar. Plastic water pipe 40 mm long, cut to length of 470 mm. They will be used to make blanks for the grousers. Then each of them is sawn lengthwise into equal parts with a circular saw.
Groomers are bolted to the conveyor belt with furniture bolts. When making a caterpillar, it is extremely important to keep the same distance between the tracks. Otherwise it will run over the teeth of the drive sprocket and the track will slip and slide off the rollers.
This drill allows six holes to be drilled in the conveyor belt simultaneously in order to attach the three track shoes. Also were purchased sprockets (2 pcs.), an inflatable rubber wheel (4 pcs.), closed bearings 05 (2 pcs.).
A turner made the bearing support and drive shaft of the caterpillar. The frame of the snowmobile was made by myself. 25×25 mm square tubing is used for this. The pivot axes of steering and ski are in the same plane and on the same line, so an uncut steering rod without ball joints was used.
Ski swivel bushings are fairly easy to make. A water coupling was welded onto the front cross frame beam, with a 3/4 inch female thread. There are external threaded spigots screwed into it. To them welded bipods ski racks and steering rods. Angles are installed on the skis, which serve as attachment to the snowmobile’s turnpike. A metal undercut is made at the bottom to control the snowmobile better when driving in packed snow or ice.
Chain tension is adjusted by shifting the motor
Control of the snowmobile is quite simple. A throttle grip on the handlebar is used to increase engine speed. This engages the automatic centrifugal clutch, which causes the snowmobile to start moving. Since the engine power is low, the speed of the snowmobile is 10-15 km / h. That’s why no brakes are provided. To stop the engine speed must be reset.
Custom track widths can be made. Choose what is more convenient to make: a narrow but long track, or a wide but short one. It’s important to remember that a larger track will put more strain on the engine and make it harder to control the snowmobile. If the track is made small, the machine could fail in deep snow.
The weight of the snowmobile with all parts is 76 kg. It includes: rudder and engine (25 kg), skis (5 kg), wheels with axles (9 kg), drive shaft (7 kg), caterpillar (9 kg), seat with struts (6 kg).
You can reduce the weight of some parts. For a tracked snowmobile of this size, the weight rating is quite satisfactory.
