How to make a snowmobile from a walk-behind tractor on wheels. Four principles for making your own all-terrain vehicle tire

Motoblock is a universal unit that helps to facilitate work on a personal plot. Nowadays, a lot of equipment is made from a walk-behind tractor: a mini tractor, an all-terrain vehicle, a snowmobile.

The snowmobile appeared in the 60s, as one of the categories of homemade all-terrain vehicle. At first, these devices were assembled as a tricycle, with the front wheel replaced by a ski. This scheme for snowmobiles is popular in our time. But the most popular snowmobile is based on a walk-behind tractor, with wheels used from three to six.

What you need to know when making a snowmobile based on a walk-behind tractor

Before creating such a snowmobile, you need to solve the following problem: what is the purpose future car? To do this, the maximum baggage weight, the desired number of seats, and the conditions in which the device will be used are specified. After finally finding out all of the above, when they determined the future concept of a snowmobile, they begin to consider options for creating a machine. Then go to the selection constituent parts and snowmobile components. To do this, determine which type and model of engine is best suited.

Choose the transmission, frame type and design and other elements. Particular attention should be paid to the choice of form running system. Design parameters are also carefully calculated: tire sizes, engine power and snowmobile weight.

After analyzing and comparing the possibilities with the desires, the all-terrain vehicle scheme is finally selected. A prerequisite for completing this stage of activity is a diagram and drawing of a homemade snowmobile.

Perfect for a snowmobile with pneumatic tires fit motor from a walk-behind tractor. For this, a motor is selected that is most suitable for the conditions of use and power. Another plus of using engines from a walk-behind tractor is the presence of air or water forced cooling because the snowmobile does not have the conditions necessary for natural cooling.

Four-stroke engines have a number of advantages over two-stroke counterparts. When choosing the type of engine: carburetor or diesel, you also need to weigh all the pros and cons. After all, both systems contain advantages and disadvantages. Compared to gasoline engine, diesel - more economical. But at severe frosts it is hard to start and unstable, without a preheater. Gasoline engines are much less susceptible to this.

What wheels to put on a snowmobile with an engine from a walk-behind tractor

When making a snowmobile with an engine from a walk-behind tractor, in most cases wheels are used low pressure made by hand. What is special about snowmobile tires? They have a relatively small weight, high elasticity, and the pressure on the ground falls within a small range. Large rolling radius and good performance give the snowmobile economy and excellent cross.

The large volume of the chambers gives the structure a greater permeability. And when filling the space inside the disks with foam, the snowmobile will noticeably reduce the sticking of dirt and snow. The simplicity of the chassis design and the availability of materials make it possible to avoid difficulties in the manufacture of a snowmobile.

Four principles for making your own all-terrain vehicle tire

• 1. Two discs made of sheet metal are bridged with each other. Then they are attached to the sleeve and the camera is put on them. It is fixed with pieces of a conveyor belt. For more protection of the camera, a protector from another camera is sometimes used.
• 2. Attach one disc to the hub. After that, jumpers are attached to it, to which side rings are riveted or welded.

• 3. The design is similar to the previous construction principle. In this case, when installing central discs a spoke from a pipe or sheet metal is required.
• 4. The fourth principle is to mount two discs on the hub, like a scooter wheel disc.

This is where we end. Of all the options, you can use the one that you like best. You just need to decide what the purpose of the machine is, and get down to business!

How to make a caracat from a walk-behind tractor with your own hands

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

In this case, you can make a homemade snowmobile. Winter vehicles are most often equipped with caterpillar drive, steering skis are installed in front. The snowmobile has high traffic, light weight (70-80 kg), which allows him to drive both on valuable snow and on rolled snowy roads. It is easy to drive this vehicle, and the developed 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 are engaged in the sale of snowmobiles in the CIS. But their prices are high even for families with decent incomes. If you don't want to pay extra money for advertising and are a hardworking and creative person, then try making a homemade snowmobile.

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

The success of your own snowmobile production depends on several factors:

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

It should be borne in mind that riding a snowmobile, like any other vehicle, associated with heightened danger. Despite the fact that home-made 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 all seriousness. The issue of operational safety and reliability of the final unit should be the main one for any person who intends to build a snowmobile with his own hands.

Preparation

Before proceeding with the manufacture of a snowmobile, it is necessary to calculate the main parameters of the apparatus. 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 arranged in the same way and simply. Your task is to make a reliable device in the model and likeness of all other variants of this class of vehicle.

What is required for manufacturing:

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

Experimentally, it was found that the optimal pipe diameter is 40 mm. If you are using a profile, then 25 x 25 mm will suffice. Wall thickness - 2 mm. With smaller parameters, the resistance of the device to deformations will be reduced. For large ones, 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. will do. In total, 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.

Of these, lugs are made - the second element of the "caterpillars". The optimal diameter is 40 mm with a wall thickness of 5 mm.

1. Propulsion system.

As a rule, use the engine, carburetor, fuel tank from a motorcycle.

1. transmission mechanism.

As a rule, they use stars and a chain from a motorcycle, stars 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 should 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 steering wheel from a motorcycle, respectively, with a throttle 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 depreciation, allow you to place several seats, and at the same time slightly burden the structure.

1. shock absorbers.

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

1. Small parts.

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

How to do: instruction

First, the frame is cooked - the frame. Obviously, the larger the frame, the heavier the apparatus will turn out and the slower it will move. Optimal length frames - 2 m plus / minus.

On the frame are sequentially fixed:

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

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

The function of the lugs is performed by PVC pipes sawn in half along the diameter indicated above. They are attached to rubber base with bolts and nuts. Not wide enough v-belts can be fastened to each other with metal lugs.

In order to be able to adjust the track tension, the rear wheel axle is mounted with a movable guide element, which allows the axle to be fixed in a certain position.

Additional notes:

1. The center of gravity should be approximately at the center of the structure. Since the power plant is mounted in front, the driver's seat should be centered over the front axle or slightly shifted to the rear.
2. The distance between the drive shaft and the power plant must be as short as possible to minimize the loss of energy transmitted to the shaft.
3. If you install a shock absorber under the seat, then the front seat support is fixed rigidly on the profile arc, and the rear seat rests on the shock absorber.
4. If you are making a snowmobile with the expectation of a large load, 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 the two tracks). This ski, 50-70 cm long, is attached directly to the frame. However, this design involves a more accurate preliminary calculation with subsequent alignment of the height of the "legs", which complicates the manufacture of the snowmobile.
5. It is advisable to keep snowmobile tires at a low pressure to avoid rapid wear details and high flow fuel.

The considered version of the snowmobile is the simplest in design. With tools, a welding machine, it can be assembled in the garage without problems.

A homemade swamp vehicle was created in St. Petersburg for hunting and fishing trips. By the way, this goal is pursued during the construction of about 80% of home-made swamp vehicles. For all its diminutiveness, it can rightfully be considered a swamp rover, because. really overcomes them, these very swamps. The video below will clearly show both the swamp and how he overcomes them.

Very interesting way to increase buoyancy and patency was used in the construction of this homemade product. We put twin KAMAZ cameras and added a protector to the harnesses like a caterpillar one - from scraps of PVC pipes. It turned out very wonderful! The disks are made, as always in homemade products, under right size using the Zhiguli disk as a basis.

With a weight of only 250 kg, it accelerates to a speed of 50 km / h. Relatively not much, but given the fact that when driving through swamps, speed is by no means the dominant factor, then it’s very good!

Breakdown with 150cc scooter engine - great lightweight homemade swamp. The fracture unit was made independently - pipes, a sleeve machined on a lathe for reaming, as well as part of the steering arm from a Zhiguli were used. All on high-quality welding.

Gearbox from Skoda - four-speed + rear. This gearbox weighs only about 15 kg. Engine from a scooter, 150 cm3. Power is enough to overcome 50-degree climbs in fourth gear.

The weight distribution of this swamp is not as rosy as it seems at first glance, but at the same time it is not critical. The fact is that the unevenly distributed weight of the structure leads to the immersion of the front part of the swamp into the water deeper than the back, which in turn is pushed out of the water.

There is no need to learn how to drive such a swamp anywhere else, but if there is a desire to acquire the skills of driving special equipment in difficult places, then some driving schools teach this as additional courses and extracurricular seminars.

And a few videos of an all-wheel drive swamp:

Each owner Agriculture knows what a motoblock is. This machine is traditionally used in vegetable gardens, although it is often used in public utilities. When this device fails or the “season” ends, many people hide it, but you can make an all-terrain vehicle or a snowmobile with your own hands from a walk-behind tractor.

What can be done

Most often, in winter, walk-behind tractors are hidden in a garage, because it is not suitable for use in snow. But since any technique needs a periodic run, you can make an all-terrain vehicle or a snowmobile out of a walk-behind tractor to use it at any time. The device is easily recyclable due to its design.

Overcome impassable areas

The all-terrain vehicle has many advantages, because it has. Since full-fledged asphalt pavement is quite rare in rural areas, this device will be able to drive on any surface, even snow. To create it, you need a walk-behind tractor with two or four-stroke motor. It is important that it has air cooling.

In the future design, the walk-behind tractor will serve. To do this, remove the bridges and steering wheel from the walk-behind tractor. Next, you need to insert the frame so that the cardans play the role of bridges. It is important not to carry out a complete alteration of the walk-behind tractor, so that at any time you can return the original device.

put together

There are many design assembly options. It all depends on the type of future device and its capacity. Chassis all-terrain vehicle must have independent suspension. It is better to supplement it with low pressure pneumatic wheels. The frame can be either articulated or solid - it depends on the type.

To provide the machine with independent support, it is necessary to connect the spars with a strut, a rack and a special steering sleeve. To attach the wheels, you need to install a chamber from the truck to the suspension (it is better to use a low pressure chamber). After installing the suspension, the motor from the walk-behind tractor is installed. At this stage, the brake, clutch and exhaust gases are connected. Such a device shows excellent cross-country ability at a speed of 75 km / h.

Movement on snow masses

In order to make a snowmobile from a walk-behind tractor, you will need power unit, welding machine, tracks (best constructed from shipping tape), although wheels can also be used. All parts are assembled on the basis of a drawing, the drawing of which is carried out only after the type of the future apparatus has already been decided. difficult enough to move, a snowmobile can overcome almost any blockage of snow.

Getting started, you need to decide on the purpose of the device. From this depends on its carrying capacity and power. It's best to start with a cardboard mockup to help you move in the right direction. Many parts are available, they do not have to be bought. It is best to choose tracks, not wheels, because they will make it easier to move through the snow.

Stages of work

Initially, you need to create a frame for which you need pipes from a motorcycle. They are given the required shape thanks to the pipe bender, after which point adhesion is carried out by welding. All parts are connected with an inextricable seam so that there are no open joints. After that, the bracket is welded to the frame element and the seat is attached. The future purpose of the device depends on the selected power and reliability of components.

To install the steering wheel and seats in a homemade snowmobile from a walk-behind tractor, you can use any surface, be it an old chair or steering bike. The number of seats for passengers also depends on this. It is important to skillfully approach the performance of work, because all elements of the device must be securely fastened and work smoothly. This will make it possible to convert the walk-behind tractor into a snowmobile, which will be able to drive large areas even in a heavy snowstorm.

How to make a snowmobile or an all-terrain vehicle from a walk-behind tractor is known to many craftsmen. This is a rational use of the device, which under normal conditions is unsuitable for use in winter. The main advantage of such manipulations is that after a cold pore, the structure can be returned to the form of a walk-behind tractor.

So that the walk-behind tractor is not stored idle in the garage, it is much better to convert it into a snowmobile or an all-terrain vehicle. But such manipulations must be carried out very carefully so as not to make mistakes and prevent accidents. Also not recommended

Give our man an engine - and he will make a walk-behind tractor, a tractor, a boat or a homemade snowmobile out of it. It all depends on the climatic zone in which Kulibin lives. And since the territory where the snow cover lies for almost half a year is quite extensive 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 craftsmen and then produced in small batches.

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

A do-it-yourself snowmobile can be made according to one of the concepts

On pneumatics

In fact, it is a mini-tractor with original wheels. Due to the large area of ​​contact 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 weight, and buoyancy of pneumatic wheels.

Classic design

With a leading caterpillar and a steering ski (skis). A project that has been tested over the years, the difficulty is the manufacture of the caterpillar itself. The vehicle turns out to be universal, it easily moves on any roads, including rough terrain. In some cases, homemade products are superior to many industrial designs.

Drive wheel use

IN this case wheels with grousers. The paddle steamer works on this principle. The advantage of the design is the relative ease of manufacture. The disadvantage is insufficient adhesion to the surface of the mover, slippage on heavy terrain is possible. Such models are well obtained from mopeds and motorcycles, giving a second life to "donors".

snowmobile

The easiest in terms of implementation, homemade snowmobile. It is enough to put the trolley on the support skis, and install the traction screw on any suitable motor. In addition to some of the difficulties associated with the manufacturing technique of the lead screw - more problems not in the building. The disadvantage is that such a design moves only on a relatively flat surface. Another problem is that with a small motor power, it is difficult to move against the wind.

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

• Using a chainsaw motor. low power does not allow you to move a lot of weight on such a vehicle. Therefore, chainsaw snowmobiles are usually single-seat;
• Moped or motorcycle. Pretty easy project to make. The engine is designed for a certain load, it remains only to redo the leading element and replace front wheel ski;
• Snowmobile from a walk-behind tractor. The design is quite complicated, but in terms of reliability it is practically not inferior to the factory one. The engine is designed for continuous operation under load, the kit includes a gearbox, which expands the capabilities of the vehicle. Besides, power plant can be filmed on summer season, and use the walk-behind tractor for its intended purpose;
• Do-it-yourself snowmobile based on a car or, using a motor from passenger car. A rather rare type of homemade products, it requires professional equipment and complex engineering calculations. But snowmobiles made on the basis of a car are distinguished by high comfort, safety and reliability.
