Snowmobile based on the snowmobile, description of photos and video
Single-axle tractor. a universal unit that helps to facilitate work on the homestead plot. Nowadays, a lot of equipment is made with the help of a motor-block with their own hands: a mini-tractor, all-terrain vehicle, snowmobile.
Snowmobile appeared in the 60s, as one of the categories of all-terrain vehicle. In the beginning, these machines were assembled as a tricycle, with the front wheel replaced with a ski. This scheme for snowmobiles is popular nowadays. But more popular is a snowmobile based on a power tiller, with used wheels from three to six.
When making a homemade snowmobile for him to use the tracks from other snowmobiles, or homemade, assembled from improvised materials. After choosing a track, you need to decide what type of suspension to use. You need to choose from two basic types: suspension on rollers and sliding suspension.
Each of them has both advantages and disadvantages. After that it is important to decide what the layout of the snowmobile will be. Usually, the snowmobile is equipped with two steering skis at the front and a track unit at the back.
The engine can be installed both in the back and in the front of the snowmobile.
Making a karakat from a power tiller with our own hands
So, how to make a karakat from a power tiller with your own hands and thus create a reliable and indispensable helper not only for your own household, but also for trips to fishing and hunting?
In the creation of such a karakat from a power tiller, it is possible to allocate the following main stages:
Choosing a frame for a karakat
Karkat of power tillers, of course, requires the designer- handyman to have a single-axle tractor, relating, preferably, to the heavy or medium class. In fact, the karakat is nothing but a self-made all-terrain vehicle, set on four or three wheels (depending on the design scheme), with the wheels “shod” in low-pressure tires, driven by an internal combustion engine.
In order for a karakat from a power tiller not to deceive Your expectations and become an indispensable vehicle for long trips to hunting or fishing on difficult off-road terrain, it is necessary to clearly imagine all the stages of its manufacturing.
To begin with, we should decide on the frame. In principle, many constructors of self-made karakats took the frame from motorcycles “IZh” or even from Ural, which is determined by the financial capabilities of the participant (kov) of the manufacturing process of the karakat, as well as by what is on hand.
The IZhA snowcat has good maneuvering properties, which predetermines its main use for driving through the woods, as well as when overcoming rugged terrain with large drops in altitude, slopes and ravines.
Making the suspension by your own hands
At the next stage of making a karakat from a power harvester it is necessary to make a suspension and a rear axle. Suspension will need to make your own hands, because the caracat suspension involves a welded structure of two parts, connected by means of hinged fasteners. In the structure of a karakat suspension the longitudinal members are connected to each other with the help of steering bushings, strut and special stands, as a result of which the independent rear and front suspensions are formed.
When installing the spars, as well as bushing handlebar and special racks, one must achieve the independence of the suspension because it is an independent suspension that is of particular importance for all types of self-made karakat, because it provides a karakat cross-country ability along with agility and softness, especially when overcoming rugged terrain.
Mounting wheels on a homemade caracat
The wheels of the future caracat are the most important and most expensive part of it. They can be purchased or made by one’s own hands. It is important to note that all known homemade constructions of these all-terrain vehicles, including even the Muravy scooter caracat, are equipped not with wheels, but only with cameras and tires of truck wheels (KAMAZ, Ural, as well as of their trailers, including the big K-700).
It is due to such wheels and provides ease of steering and overcoming the rough terrain, which ultimately ensures the safety of riding on such a caracat all-terrain vehicle. The considerable volume of the tubes gives the karakat with these wheels good buoyancy, which is a useful addition to its good cross-country capability. Sometimes karakats are equipped with simple chambers attached to the suspension through the wheel rims and metal bands that cover the outside of the wheel chamber and are attached to the rims.
Installation of the engine and its complementary systems of torque transmission to the drive wheels. After installing the suspension with wheels on the frame of the karakat, you can proceed to the installation of the engine, as well as all of its other complementary systems. clutch, braking system and the system of disposal of the products of burned fuel.
Once this is completed, it is required to comprehensively test the carriage, and only after the successful completion of the test it can be fully exploited.The power of a single-axle tractor (big or medium capacity) at the disposal of a home builder of a karakat will depend on it.
Shop drawings and assembly
To make a mini-tractor from a power tiller with engine with your own hands, you will need to prepare the drawings and assembly diagram in advance. You can work on it yourself, but the main condition must be met. there must be a balance in order to avoid unpleasant “surprises” in the work of the machine.
How to make a carcass
You don’t need a lot of material to create the frame. In this case, if something is missing, you can use analogues. But the dimensions and properties should be similar. We are talking about:
- You need to prepare the angles, the channels and the square tube. For cladding you will need steel with a thickness of at least 1.5 mm;
- steering device;
- wheels and axles;
- the bearings;
- tape measure, welding, drill, angle grinder.
Assembly is carried out only according to the scheme. no deviations from it.
Once all the elements have been connected, it is necessary to check whether the assembly was done correctly. To do this, you must mount the frame on a single-axle tractor. If everything is as it should be, you can continue to create the mini-tractor. If something has gone wrong, you need to fix the.
In the next stage you need to install the ready elements: steering rod, hubs and the axle, on which the wheels are bolted. The first element should be mounted on the back axle.
That’s all assembly. now you can start test runs. It is important to run the machine on a level surface. Often it is necessary to adjust the steering and position of the wheels additionally. If there are no complaints, you can attach the attachment and proceed to the field test.
Not everyone is engaged in an independent rework of a power tiller, as this process is laborious and requires attention. And if you consider that there is a ready-made tractor from power tiller Neva, it makes no sense. But that’s when you want to do small jobs.
If the work will be carried out on an uneven surface or viscous type of soil, then you can not do without a mini-tractor.
3 Swamp buggy and snowmobile
Swamp buggy and snowmobile have one requirement. minimum ground pressure. Wide wheels are made for this purpose. Crawler tracks from Buran snowmobile are used as attachments. They are well matched to the standard wheels of the power tiller. Put on the primers by lowering the wheels and inserting them inside the homemade “lapti.
After inflating the tires they are pressed into the grousers. If a heavy machine is used to make a snowmobile and swamp buggy, the structure of the technique remains almost unchanged. For the snowmobile often buy an attachment, which is equipped with a power tiller. The design consists of a supporting frame, provided for the attachment of the motor-block, solid tracks and suspension elements. After the above-mentioned manipulations, you will get a versatile and multifunctional vehicle that can move over the bumps, snow. by Menu
How to make a homemade wheeled cross-country vehicle
Example drawing of a cross-country vehicle on low-pressure tires
It makes sense to equip the base unit with a reduction gear. The reason is that gasoline and diesel engines have the best indicators of torque at crankshaft rotation speed of about 75-85% of the maximum.
Engine must have forced cooling system. When driving at a low speed the overrunning flow will not be enough to maintain the optimum thermal regime.
All-terrain vehicle frame
A frame is created between the front and rear axles. The basis is better to use rectangular or square section profile tubes. They provide greater stiffness than rolled angles, channels and I-beams of the same mass.
The docking of the elements of the frame of a wheeled cross-country vehicle can be rigid, then it will be formed in a single-volume format. When using a heavy power tillers “Neva” or MTZ this variant will be preferable.
As an option, a breakable frame (fracture) is made, a variant used for terrains with a complex profile. Here the articulation is made with a kingpin. The front and rear axles have independent suspension. Such cross-country vehicles are created by craftsmen on the basis of power tillers “Neva” and “Ugra”.

For hunting and fishing it is better to have a wheeled all-terrain vehicle with a breakable frame. Its cross-country ability is higher than when using a rigid frame design.
Rear axle and suspension of the homemade all-terrain vehicle
Some selfmade car makers use a ready-made rear axle from a passenger car to simplify the design. For example, from the car “Moskvich-412”: its small weight allows you to perform installation on a light all-terrain vehicle. Suspension is made on shock absorbers for a smooth ride and reduced vibration.
Other masters make an independent suspension for each rear wheel. This approach is implemented on the scooter “Muravey”. A slight rocking motion is felt during driving, while at the same time the wheels experience less resistance on irregularities, markedly reduced fuel consumption.
The rear axle is connected to the frame with long hardened bolts. Rubber inserts, such as silent blocks, are used for elastic articulation. This improves the performance of the all-terrain vehicle on the basis of a power tiller.
Rear axle on skis is used in winter time. Resistance to movement is minimal, and the construction is greatly simplified.
Wheels (low pressure cells)
To move on wet and quicksand you can use the grousers. They provide high traction. Even better are large diameter low pressure tubes. Pneumatics have a minimum pressure on the ground, and the presence of air enclosed in the chambers of the rover, will create a floating rover.
Homemade or special wheels for all-terrain vehicles, marshmobiles and snowmobiles are used for mounting on the rear axle. Buy them as a set or separate elements: tire, tube, disk. Simply assemble the wheel.
- Homemade discs for pneumatics are made by welding together regular discs and mounting plates with metal tubes. Such an expansion is necessary in order to fit the small diameter of the car disk under the large chambers and better fix them.
- On a specially enlarged disk put a large camera. either proprietary, or from other units (GAZ 53, Ural, Kamaz or other truck, aviation camera, etc.п.).
- The air valve is inserted into the hole in the disk.
- The wheel is inflated with air.
- The resulting tires are installed on the all-terrain vehicle self-made.
It is possible to increase passability of ordinary wheels on low-pressure cells by creating additional tread. For example, to further secure the cameras with chains, conveyor belt, homemade tracks or other method.
Another option is to cut the grouser from the tire. The depth of the hook of the construction reaches more than 20-25 mm. The rolling resistance increases and at the same time the slipping ratio is drastically reduced.
Assembling a self-made all-terrain vehicle from a power tiller
When all tools, parts and accessories are prepared, you can start assembling. This is an approximate plan of how to assemble a homemade all-terrain vehicle, everything depends on the chosen design.
- A single axle tractor is mounted on the welded or finished frame.
- The rear axle and, if necessary, the front axle are mounted.
- A seat is mounted on the frame.
- If the drawing and scheme provide, the installation of steering.
- Protective equipment is attached to the frame, it is made of plastic or metal sheet.
- The future driver has to test the convenience of the landing, if necessary provide auxiliary devices to adjust your landing.
- Checking brake functionality.
- Electrical circuits and lighting fixtures are installed.
As individual elements and assemblies are manufactured, their operability is tested. This provides for a fivefold safety margin.
After completing bench testing, proceed to field testing. Need to know how the machine behaves in tough conditions.
Homemade snowmobiles from a power tiller
Not every single-axle tractor is convertible to a snowmobile, so before you buy a power unit, pay attention to the following technical features:
- The presence of the rear coupling device.
- Engine. at least a medium class.
- Manual control is mandatory.
- Equipping the motor with air cooling.
When the power unit is purchased, proceed to its conversion. The main tools and parts that will be needed make up a short list:
The main thing is to pick up all the parts needed for the transformation. Some of these are made by yourself. Construction begins with the choice of snowmobile model. Snowmobiles are divided into two main classes: the wheeled snowmobile and the tracked snowmobile. It is desirable to make a model beforehand.
Turning a power tiller into a snowmobile
The first and second stages are to make the frame and attach the power unit:
- The frame is made from old pipes of a motorcycle or car. A pipe bender will help to shape it.
- The joints are processed by spot welding.
- The motor is moved to the center of the housing.
- We place the engine on a specially made platform with fasteners to fix the motor itself.
Mounting the motor on a special platform is very important, because otherwise it can be clogged with snow and as a result burn out.
Installation of the rudder and landing place is chosen by the master himself. the main thing is to be comfortable to manage the machine. Depending on the motor power, the snowmobile can accommodate several passengers.
The third step is to install the skids. Most often it is two wide skis, which are attached to the steering column with hinges. The front part, which mounts the skids, must be equipped with shock absorbers.
Instead of skis you can use tracks or wheels (pneumatics). Each option has its own pros and cons.
Mini-snowmobile with their own hands
Mini snowmobile. a very popular means of transportation in the winter season. Such a unit is found in the suburbs, and in the countryside it is simply indispensable. That said, mini-snowmobiles have a lot of advantages over standard snowmobiles:
- High passability and maneuverability.
- Economical fuel consumption.
- The way of making a mini-snowmobile is not difficult.
- Affordable manufacturing materials.
- Takes up little space in the garage.
Compact size and minimal weight allows the machine to pass through the most hard-to-reach places and practically does not fall in soft snow. If you think through all the nuances of manufacturing, you can get by with minimal financial costs to re-equip the machine.
Snowmobile skids and engine
Skids are one or two wide skis attached to the steering column on an articulated joint. Shock absorbers. this is the best solution for making the front suspension. Lever-arm shock absorbers used on motorcycles are best suited for this purpose.
How to Attach Power Tiller Trolley
The engine and gearbox are installed on the drive part of the assembled snowmobile. Here you need to decide in advance whether to use tracks or wheels to move. Both types of drives have advantages and disadvantages.
Installed at the rear drive wheels allows the snowmobile to be more maneuverable, thanks to its light weight. But in order to avoid the wheels slipping on loose snow, they need to be equipped with chains. If you use the crawler, the cross-country ability of the snowmobile increases, but its weight increases significantly, which reduces maneuverability.
Step-by-step instructions for assembling a snowmobile from a power tiller
After a successful test, the snowmobile is cleaned and painted to protect the external metal parts from corrosion.
