Crawler modules on power tillers. Overview, characteristics, models

Crawler attachment to the walker u-tractor: review of manufacturers

Caterpillar module for a walking tractor is an attachment that allows you to convert the equipment into a snowmobile or power tiller. And it can be done in a matter of minutes.

To make a caterpillar drive on the recreational tractor with their own hands may require a drawing.

Under the brand name “Krutets” cassettes are produced, to which every manufacturer’s motoblocks are addressed, regardless of the power and weight of the cultivator. They have a sturdy frame and can work in any season. The attachment is installed with buttons on the power tiller.

Well-known power tiller attachments include the “Lynx”, “Muravy” and “Buran”. Imported ones include: Talon 380, Talon WTI DR.

As for the caterpillars, which are made with their own hands, it should be remembered that their high height increases the center of gravity of the unit. This threatens instability and overturning on turns and problematic areas. For stability you need to increase the additional axle.

If the wheelbase is narrow, it must be widened. A bushing needs to be installed on the driveshaft. It can be purchased at any auto parts store.

It just won’t hold a lot of load. Water-cooled motor blocks are ideal. With this cooling, the engine does not overheat.

Crawlers for walker k-Tractor allow fans of winter outdoor activities – fishermen and hunters – to come to the right place without hindrance. Also on such a machine you can transport a variety of cargo, hay or firewood.

Reviews about homemade caterpillars are positive. When making tracks independently, you can not save on small things and details, otherwise the tractor will turn out unreliable for walks. Or you will have to buy homemade attachments from craftsmen who have repeatedly engaged in the manufacture of tracks for power tillers.

If you are not confident in your abilities, it is better to buy a ready-made attachment. Its disadvantage is only the high price.

Design features of the device

Making components of a domestic track for a walking tractor with your own hands allows you to save money on the purchase of factory equipment and the further operation of the equipment. If everything is done correctly, then the caterpillars for tractor Wal k-behaviour made with their own hands will increase the cross-country performance.

Compared with their wheeled counterparts, crawlers are not so widespread. The explanation is simple. Wheeled units Texas, Patriot, Kayman, Viking, Forza are the most adapted for plowing the land. This design is best suited to the floor.

Replacing the tractor with a wheeled undercarriage is a task, which is an additional wheel on each side. You get a four-wheeled walking tractor on which you can carry caterpillars. Again, they can be purchased or homemade. It is possible to complete with additional wheels. This allows in time to turn the device into a standard walking tractor, ideal for work in the garden.

For this purpose, the wheels are attached to the axle already provided in the design by means of a rigid or elastic transmission. Such a solution is considered appropriate, because it eliminates the need to install additional fastening elements. The devices of these walking tractors fully correspond to the parameters of the wheel modifications:

1. Engine. It is powerful, four-stroke. It has an axle locking function. This allows the tracked two-wheeled tractor to turn on the spot without describing a full circle.
2. Transmission. A gearbox, clutch system, and reducer are standard.
3. Undercarriage. This is where the tracks come into play. They replace the wheelbase. When modifying the existing pair of wheels, one goat is added on each side. A homemade track is put on.
4. control points. Located on the control handle. Includes emergency stop mechanisms and various types of clutch levers.

Before you start making your own, you need to assess the offers in stores that specialize in the sale of such equipment. Particular attention is paid to the price of certain types of tracks from reputable manufacturers of walking tractors. For example, a track for a walking tractor “Neva” costs about 28,000 rubles. This is a fully functional attachment for the snowmobile. Separately, you can buy a driver’s seat, thanks to which the crawler tractor will acquire the characteristics of a crawler mini-tractor, although with less impressive characteristics. Technical parameters are as follows:

• develops a speed of about 18 km per hour;
• weight of the console is usually 37 kg;
• width – 60 cm;
• length – 100 cm;
• height – 34 cm.

One driver and one passenger are accommodated on board. In addition, in the offer you will find attachments for the walking tractor on crawler tracks, designed for the models “Salut” and “Agat”. The price ranges from 25 to 27 thousand rubles. This design does not provide for the attachment of the driver’s seat. Because of this, some restrictions are imposed on the functionality of this device. But for driving on off-road and snow, such a vehicle is quite suitable.

Their peculiarity is the ability not only to walk behind the walking tractor with two hands, but also to sit in a folding wheelchair. The latter must be purchased separately. If you consider that the average cost of the mount is about 30,000 rubles, not including the price of the folding sledge, then we can say that making the tracks yourself will save a lot of money.

What are the types of caterpillar systems?

In one case, the caterpillar module is made in the form of an axle. From below, it is supplemented by four rollers. And already with the help of rollers the necessary mechanical tension of the caterpillar belt is formed. On the left and right are two gears. You get into the grooves of the guides, pull on them and let the unit move.

The horizontal movement of the gears is done with a special frame. It is attached with bolts. One side of the shaft, equipped with gears, is supplemented with a gear transmission. Using a special arrangement, it transmits power to the track unit. The running belt has V-shaped parts built into it, the sharp edge of which looks along the two-wheeled tractor.

There is also another version of the drive. It is not reflected in the structure of the track itself. Only the wheels are replaced by a large pinion attached to the axle. The frame is equipped with eight rollers on the underside. The purpose of using these rollers is to keep the belt taut and ensure smooth movement.

How to make caterpillars for a caterpillar tractor with their own hands

Consider how to make caterpillars for a caterpillar tractor with your own hands. For the self-assembly of the caterpillar you can use a variety of materials that are easy to find. List of materials and tools needed to make a caterpillar:

• grinder;
• drill;
• puzzle;
• welding machine;
• Bolt;
• Nuts;
• Wrench;
• Knife;
• Screwdriver;
• Pliers;
• Abrasive tapes;
• chains.

During operation, the crawler drive of a two-wheeled tractor must distribute the load evenly over the ground. Therefore, it must be strong and lightweight at the same time.

It is best to use roller chains with a conveyor belt. To get a track from the above materials, you need to sew the edges of the chain and the belt.

To do this, you can use a machine or sew by hand. But this method is unreliable. A loop, similar to a piano hinge, will also be suitable for joining.

Consider how to make homemade tracks for a crawler tractor from tires. There is another way to create homemade chains for the device – using the tread of a tractor or car tire.

Such tracks are easier to make and much more practical. This method has another advantage – it is not necessary to prepare separate tabs.

The method of making: first you need to take the tire and carefully cut the track with the tread. If you do this by hand, you will need a well-sharpened knife. But, as practice has shown, it is better to use an electric jigsaw and a fine-toothed file.

To reduce friction, when working with a jigsaw, you should from time to time wet it with water or a special soapy solution.

The advantage of a tire track is that it is initially round and has a closed circle. The disadvantage may be the limited width of the tire.

Consider the process of making a belt and chain product. Chains can also be made from standard V-belts. They are connected by eyelets, which are attached to the belts with screws and rivets.

When making tracks from chains, they must be the same size. The chains are riveted, closed into a ring and welded together. Docks can be made from steel plates to which chains are bolted.

They have a circumferential diameter of 30 mm. These chains are not suitable for heavy hand-held tractors such as MTZ or Agro.

Prefabricated tracks for tractors with a walking engine are very easy to assemble. They serve as attachments.

Crawler platform, types, modifications

These devices are produced by both domestic companies and foreign manufacturers. In this regard, there are many modifications, which differ from each other:

• inform;
• according to the principle of installation;
• in the process of operation.

forms of modules

Of the variety of models, two main forms can be distinguished:

1. rectangular axial;
2. triangular toothed.

Axial fasteners consist of:

• platform;
• axle;
• four rollers;
• two gears;
• two tracks.

The platform is attached to the two-wheeled tractor with screw connections. Four rollers are attached to the underside of the axle. The rollers create the necessary chain tension. Two gears on either side of the track, caught in the groove, set the platform in motion.

The triangular gear attachment consists of the following elements (separately for each crawler):

• large equipment;
• rigid frame;
• eight drums;
• caterpillar.

Crawler drive triangular

The large gears are mounted on an axle coming from the Walk behind tractor transmission. The rollers are attached to the rigid frame at the bottom and are arranged in pairs on both edges of the rail. This design provides the necessary track tension during travel. Unlocking the differential allows the tracked tractor to perform various maneuvers – turning, turning, etc.

When deciding to buy (or make it yourself) a track drive for a tractor with tracks, you need to consider the following characteristics of the attachment:

1. Optimum speed of the tractor on the track chain. Powerful models can offer a speed of 18-20 km/h.
2. Carrying capacity of the attached equipment. In most cases, models with a carrying capacity of 200 kg are purchased, but each owner of the equipment has the right to choose and select this characteristic for their own needs, taking into account the power of the engine of the power tiller.
3. The maximum permissible height of snow masses (if you are going to use the implement and walking tractor as a snowmobile). The main limiter is the height of the engine. Modern attachments allow you to move comfortably on snow up to 50 cm in height.
4. Permissible amount of liquid mud and water is also from 45-50 cm, the reason is the same – the height of the engine.

To ensure service life and functionality of all elements of the module, it is necessary to perform the following activities regularly (before and after each operation):

Check the attachment of the tracks before driving. Check the tension of the rollers. Check fasteners are secure. Pay attention to integrity of tracks, condition of tracks. Regularly lubricate all moving parts of the chain structure.

Installation

The uniqueness of a tracked attachment is that installing it instead of a simple wheel drive turns an ordinary tractor with tracks into an effective tractor, off-road vehicle or snowmobile in a matter of minutes. Such modernization is most relevant for devices belonging to the category of small agricultural units with a shaft diameter of 30 mm. The crawler module can be fully assembled or assembled separately. For the second option, you can easily find drawings and video instructions for assembly and installation on the World Wide Web.

Qualitatively purchased and well-made DIY tools are characterized by increased strength and durability. Not to forget the ease of installation, operation and maintenance. Installation of a purchased platform of any configuration and complexity does not require special knowledge and technical means. Basic skills and minimum tools will be enough. Installation of homemade units has a number of nuances. It should be noted that too high a platform shifts the center of gravity of the entire machine, which in turn negatively affects the stability. This significantly increases the risk of tipping the two-wheeled tractor on off-road and when maneuvering. In order to increase stability when installing the tracks, it is necessary to place an additional axle higher.

In addition, the width of the axles must be considered. Experienced owners advise to increase the wheelbase if necessary. If there is no differential, a swivel extension can be used as an effective alternative. This triangular device has a positive effect on the maneuverability of the tracked two-wheeled tractor

When choosing by purchasing, building and installing a crawler drive, keep in mind that such an upgrade is not relevant for air-cooled models. This is due to the excessive load on the power supply device

Requirements for converting devices for a tracked train

The figure shows the simplest design from home – a car with tire tracks.

The conversion of equipment into GDM is carried out solely out of useful considerations of pragmatic owners of vehicles or motor vehicles who wish to improve all the qualities of their “helpers”.

For all models of devices designed to ride on the spot, the market offers commercially available variants of GDMs of industrial production.

However, all this costs a lot of money, and the tires come free or become very cheap.

Regardless of the type of car or power tool, craftsmen consider the following factors:

1. In order to install GD mechanisms, it is necessary to equip special frame structures of increased strength and rigidity that can withstand the increased weight and dynamic loads.
2. When using improvised means, many craftsmen use pneumatic wheels as a tensioner, as well as several leading and driven wheels. Duct tape is put on deflated bicycles, which are then inflated, which creates the necessary tightness of the track.
3. The owner of the equipment must clearly determine the purpose of the machine in order to select the optimal width and length of the crawler strap.
4. Considering the increase in engine weight and traction load after installing the GC, you must optimize the match between maximum engine performance and track belt width. Otherwise the engine will fail quickly.

When selecting the ratio of engine performance to belt width of a homemade track installation, you can use price list data to focus on the size vehicles that are equipped with commercially available tracks.

Below are the categories of machines that are most popular with craftsmen for track-mounted alignment.

NEVA engine tracks. Caterpillar module overview

Currently, there are a large number of different power tillers on the market. They are produced by domestic and foreign companies. With their help, it is possible to perform various tasks and purposes. The NEVA power tiller allows the use of a large number of compatible attachments.

Besides, it is possible to replace standard wheels and tracks. They give the NEVA tiller extra stability and cross-country ability.

Often it’s necessary to work in wet ground or snow. Such conditions primarily require cross-country ability. And caterpillar modules for NEVA undercarriage allow not to worry about this parameter.

Here’s a video example of snow removal via NEVA undercarriage with a crawler module in conjunction with a snow removal attachment:

description

Starting the review of crawler modules for walking tractors, I want to say that these attachments have proven themselves not only during agricultural work. No less relevant modules and in winter, when it is quite problematic to pass through snow-covered areas.

A caterpillar-driven motorcycle can be used throughout the year. The operation is relevant for:

• Specialized work on heavy or swampy soils;
• Clearing areas of snow with a snow blower attachment;
• Transportation of goods across impassable areas;
• And also as a vehicle for winter fishing or hunting.

The main advantage of Caterpillar vehicles is the following:

• the best traction on the floor, which means the best crossing;
• greater machine stability due to more even weight distribution;
• ability to work with a variety of attachments;
• Quick transformation from wheel drive to track drive and vice versa.

We recommend watching a video about power tillers in the pursuit train:

What materials are needed

A powerful engine is needed to convert the wheat modules to crawlers. It must have an axle unit. Power is important because the machinery drives on heavy roads. It is unrealistic to maintain good maneuverability without improvements. The basic building materials needed:

1. Block unit with gearbox, 4-stroke engine, block option.
2. Several additional wheels for the track.
3. The track attachments themselves.

Depending on what kind of construction material is used in production, two automatic openings with a good diameter and conveyor belt may come in handy. If you include a platform here, you get a compact tractor.

Considering! The optional platform uses the equipment as a terreneur when driving on a snow-covered freeway.

If you’re choosing construction materials to walk the track with your own hands, it’s important to consider that it doesn’t have to be complicated. The block system is not equipped with a powerful engine, it just can not cope with heavy loads and breaks down. Caterpillar modules are made of:

Caterpillar modules are made of:

1. Mothballs.
2. Chain.
3. Tube.
4. Belt.
5. Belt transport in symbiosis with the arm chain.

As a rule, attachments are made for the motoblock auto-openers – these elements can be converted without any problems. Given the available protective pattern and shape, it is more correct to take the autoworks of large trucks, as the pattern improves the grip on the street. Tractor tires or elements of other large machines fit perfectly.

The profiled pattern can ensure full contact with wet soil and with icy roads covered with snow. In addition to Caterpillar module materials, you’ll need a tractor with a reference point and some car wheels to make a complete unit. If you repair the car and, if desired, also with skids to carry significant loads on snow drifts.

Crawler platform, types, modifications

The platform is attached to the two-wheeled tractor with screw connections. Four rollers are attached to the underside of the axle. The rollers create the necessary chain tension. Two gears on either side of the track, caught in the groove, set the platform in motion.

The triangular gear attachment consists of the following elements (separately for each crawler):

The track drive triangles are seated on an axle from the engine block gear. The rollers are defined at the bottom of the rigid frame, they are arranged in pairs on both edges of the track belt. Due to this design, it is possible to provide the necessary tension to the track during travel. If the differential is unlocked, it allows the tractor to perform various track maneuvers – turns, U-turns, etc.

This is important to know!

When deciding to buy (or make it yourself) a track drive for a tractor with tracks, you need to consider the following characteristics of the attachment:

1. Optimum speed of the tractor on the track chain. Powerful models can offer a speed of 18-20 km/h.
2. Carrying capacity of the attached equipment. In most cases, models with a carrying capacity of 200 kg are purchased, but each owner of the equipment has the right to choose and select this characteristic for their own needs, taking into account the power of the engine of the power tiller.

To ensure service life and functionality of all elements of the module, it is necessary to perform the following activities regularly (before and after each operation):

1. Check the cabinet before traveling.
2. Check the degree of tension of the rollers.
3. Check that the fasteners are secure.
4. Pay attention to the integrity of the tracks, the condition of the track belt.
5. Lubricate regularly all moving parts and components of the track structure.

Additional tips

Before you start making a homemade caterpillar, you need to determine the appropriate parameters for this. The fact is that in the case of a very large production of the track, it is necessary to change the focus of the behavior of the undercarriage, which will inevitably lead to some problems when turning, as the assembly is shifted to the side.

To prevent this, the second steerable axle must be enlarged by a few centimeters. It is also possible to extend the wheelbase in an already available tractor. It is enough to buy a bushing in a special store. Later it will be installed on the leading wave. In addition to engine power requirements, you need to consider the cooling system.

Air cooling is not very effective at high loads, which is fraught with significant engine overheating. It turns out that it is best to provide engines with water cooling.

Connecting the track to a recreational tractor can greatly increase the power of the unit. For this reason, it is possible to increase the area of potential work that the device can do with its own hands. In other words, the resulting base wins out over a conventional wheeled base in certain cases. But the change in the tractor’s walking behavior does not always suit the owners of these units.

We are talking about special requirements to the engine. It must have sufficient power. If we talk about the machining process, this work is quite realistic to do at home. For this reason, it can be considered as a significant alternative to crawlers, which can be purchased in modern stores.

Make

The crawler attachment on a tractor with a walking engine is not as complicated as it may seem at first glance. It can be made from improvised materials, using a welding machine and some devices (tools). In homemade attachments, the tracks can be made from the following materials:

• chains;
• belt with a wedge-shaped profile;
• truck tires;
• conveyor belt.

When choosing a suitable drawing for the future construction, it is necessary to think over and ensure the convenience of mounting and dismounting of the cultivator-walker. All work takes no more than 10-20 minutes. The second criterion is the ease of assembly, because the walking tractor operator must assemble and disassemble the attachment himself.

Here is a schematic diagram of the crawler attachment with a four-wheeled engine unit:

Pay attention to the weight of the future attachment: the higher the engine power of the two-wheeled tractor, the heavier the attachment can be; if the engine is low-power, the attachment should be as light as possible.

How a homemade walking tractor on tracks looks and works – we recommend watching the video:

About the manufacturers and characteristics of the devices

Before you stop your choice on a particular brand, it is necessary to make it clear: the attachment always comes in a factory-assembled version. This eliminates errors and problems that arise during self-assembly.

The differences between individual models concern:

• the size of the belt with caterpillars;
• the properties of materials;
• the number of roles;
• launching methods.

Among Russian companies stand out “Muravy”, “Lynx” and “Buran”; foreign suppliers should prefer “Talon”.

For about 28,000 rubles you can put rubber tracks on the crawler tractor “Neva”.

If you install seats for the driver, you can bring the design closer to a crawler mini-tractor. If the design loses the ability to add a driver’s seat, it costs a little less.

Despite the weakened functionality, such propulsion systems work quietly in winter conditions. They confidently overcome both off-road and snowy slopes. The main problem is the relatively high cost of construction. Often people struggle with this, trying to make tracks with their own hands.
