Attachments for motoblocks - improvement and modernization of the main working bodies
Attachments for motoblocks have always been of particular interest to homemade craftsmen. A simple and at the same time universal device of the power unit of medium and heavy motoblocks allows you to create several types of attachments. And this means that all these relatively simple devices will make the walk-behind tractor a real competitor to a modern tractor.
Homemade attachments for motoblocks
This approach to the formation of a fleet of agricultural machinery makes it possible to take into account all possible features of both the site and the owner himself in the process of designing and assembling inventory.
The equipment under development for the unit is conventionally divided into equipment:
- universal purpose;
- highly specialized focus;
- auxiliary equipment and devices that make it easier to control the walk-behind tractor.
The universal means primarily include adapters and all kinds of trailers that make walk-behind tractor a universal transport platform both for the transport of goods and as a convenient vehicle. Some models of motoblocks are capable of speeds up to 25 km per hour. Although the comfort of a mini tractor is still far from here, it is no longer necessary to walk.
Highly specialized types of equipment are most often designed to perform only 1 or maximum 2 operations. However, these are the most popular tools from the point of view of consumer qualities for high-quality soil cultivation, performing operations for the care of crops, harvesting forage, and even used in construction. In part, it should be noted that among special-purpose homemade products, relatively simple types of tools prevail - plows, cutters, hillers... This is something that can be done from scrap materials and using the simplest power tool. But more complex elements are made using units from other equipment.
And, of course, what makes it easier to control - a counterweight for a walk-behind tractor, wheel weights and anti-slip chains, all this allows you to work with the unit all year round.
Homemade products for a walk-behind tractor
The question of where to start designing attachments for walk-behind tractors is quite reasonable. The fact is that almost all motoblocks are equipped with trailers, factory sample, designed to use standard types of equipment.It is necessary to clarify that it is the standard equipment that does not meet the needs of buyers - the trailed systems turn out to be too delicate and fragile when used in harsh operating conditions.
For domestic motoblocks, trailers are mainly made of steel by a welded method, but for mass Chinese production, it is mainly cast iron, or an alloy of metals. It is clear that for one body plow, even the most powerful cast iron adapter will not withstand.
Because the first thing that needs to be created is a do-it-yourself plow trailed to a walk-behind tractor. Here, it is better to take the standard scheme as the basis for the design - the adapter is a hinge with the ability to fix the plow in different positions, which is especially convenient for plowing small areas when a plow is used with both left and right plows.
The adapter itself is recommended to be made with the possibility of fixing not only in the vertical, but also in the horizontal planes using lanyards and bolted connections.
This option will help you use it for plowing, and for hilling, and for installing a seat adapter for a mower or a rake for turning hay in hayfields.
Universal trailer for walk-behind tractor
The presence of a trailer provides mobility, because it is one thing to drive a walk-behind tractor with already installed units, another when a plow, milling cutter or potato planter are simply loaded onto a trailer and transported by the walk-behind tractor.
It is necessary to calculate the parameters of trailed equipment for a walk-behind tractor based on its power, the principle here is simple - 1 liter. from. means the ability to transport 100 kg of payload on a trolley. The simplest and most reliable scheme is a single-axle trailer with a central axle load. And although the carrying capacity of such a trailer is small, only up to 500 kg, this is quite enough to install a seat on the trailer and operate the walk-behind tractor while sitting on the trailer.
The most difficult thing here is to select the necessary components. It is easiest to use ready-made parts. For example, a do-it-yourself hub for a walk-behind tractor is made from an automobile, for passenger cars. This allows the use of standard vehicle wheels and tires for the equipment of the unit. On the other hand, the hub from the VAZ classics is perfect for making other useful homemade products - lugs, winches, wheel weights.
For the trailer, a rectangular pipe structure is mainly used, but both a channel and an I-beam can be used as a frame base. It is better to provide for the sides for the trailer removable. It is preferable to immediately provide for the possibility of installing several types of boards on the platform:
- wooden or metal for the transportation of bulk cargo;
- lightweight, mesh for the preparation of green mass for animals;
- folding, with the possibility of increasing the usable area for hay transportation.
But in order to move comfortably on the roads, it is worth making wings for the walk-behind tractor. Install mud flaps on them if possible. After all, not all roads have asphalt and hard surface.
A walk-behind tractor with a trailer cannot be called a vehicle according to the law today, but this does not mean that the trailer should not be equipped with light signaling means.
Be sure to install at least 4 reflective elements on the trailer - 2 red at the rear and 2 white at the front. This will help the driver to identify the vehicle in the dark.
Tillage tools - a plow and a plow for a walk-behind tractor
Before you make a hitch to a walk-behind tractor for tillage, you should decide what is more important and prioritize in terms of the technique of processing the site. For large areas used for planting potatoes, root crops, grain crops, the best option would be a do-it-yourself plow for a walk-behind tractor. To make it easier and easier.But for beds for vegetable crops, for processing strips between the rows of a garden or final processing for planting, it is better to make a cutter. This will greatly facilitate further work.
With the ready hitch on the walk-behind tractor, the most difficult thing in the manufacture of a plow is its shape. The body has a shape that is difficult to form and therefore it is better to make a plow from several components. Do-it-yourself opener for a walk-behind tractor is best made of steel. The great force that this element will experience should not lead to its deformation. Moreover, it is the opener that is responsible for the plow lowering depth.
The plow share must be as hard as possible. This is the part of the plow that cuts into the ground and cuts through its seam. The strength and power of this element will allow you to work with a plow both in the conditions of arable land and to do preliminary processing of virgin lands. Despite the complexity of the blade design, it is quite simple to make it. For a curved blade, it is better to take a ready-made round or oval blank. Make a dump from it according to the drawing. Craftsmen for this usually use large pipes from 350 mm in diameter or gas cylinders. The moldboard is almost perfectly shaped.
One of the questions of how to make a plow for a walk-behind tractor will be the manufacture of a field board - a stabilizing element for the plow, which sets the direction of its movement when working on arable land.
A do-it-yourself plow for a walk-behind tractor, just like a plow, is assembled from several elements. True, to use the plow in soil cultivation, it is better to provide a dump from the reinforcement, so that during the cultivation the soil looses as much as possible when the seam turns. In the design of the plow, it is better to provide not a frontal dump, but a double-sided dump with reinforcing rods.
DIY milling cutter for walk-behind tractor
Attachments for a walk-behind tractor in the form of a ground cutter can be used mainly for light and medium-sized units. For heavy models with a separate power take-off and torque transmission to trailed units for a walk-behind tractor, milling cutters with a chain drive will be optimal.
The simplest cutters for loosening the soil can be four segment reciprocating cutters. Structurally, such a cutter is a pipe on which reciprocating cutters are rigidly planted. For medium and light units, the axle shafts for the walk-behind tractor are made collapsible. This allows you to adjust the width and speed of soil cultivation. If two segments are installed on each side of the gearbox, the processing speed is significantly higher. True, the width in this case will be small. For semi-axles of two or even four elements, the working width can be increased up to 1.5 meters.
Do-it-yourself attachments for a walk-behind tractor are made from a profile pipe. The profile is easier to install on the wheel reducer. And it is much easier and easier to articulate them when building up.
It is enough just to insert them into each other and secure with pins. Do-it-yourself half-shafts for a walk-behind tractor are made from a square or hexagonal pipe with thick walls. For 1 set of cutters you will need:
- pipes for the semi-axle body with a wall thickness of 2.5-3 mm and a length of 50-80 cm;
- for connecting pipe segments of a smaller diameter 50-60 cm long;
- 8 saber elements for the working body;
- semiaxis clamps - 4 pieces;
The cutters themselves are recommended to be made from steel strip with a thickness of 5 mm or more. The best solution for making cutters is to use forged metal. In this case, the strength is higher and there is no need to frequently sharpen the tool. It is recommended to use, when developing the shape of a cutter for a walk-behind tractor, do-it-yourself drawings of the most successful models - a saber, curved or cutter with a triangular pointed element.
Disc cultivator for walk-behind tractor
One of the most popular types of attachments for a walk-behind tractor during the summer care period is a cultivator.You can make a do-it-yourself polisher for a walk-behind tractor:
- following the example of a classic cultivator in the form of a trailed ripper;
- in the form of disc hillers used for processing root crops.
The processing technology provides for the passage of the walk-behind tractor between two rows of crops or when using a multi-body cultivator of three or even four rows.
Ripper hiller can have several types of tools installed in one body:
- ripper;
- two double-plow flat-cut plows;
- 2 disc harrows for the formation of ridges;
- two discs for plant protection.
Do-it-yourself plant protection discs for a walk-behind tractor are usually made of sheet steel. Depending on the purpose of the device to which they will be applied, their diameter is calculated. For cutters, usually the diameter is less than the cutters by 5-7 cm, and for a cultivator, they should be 30-35 cm in diameter. It is just that during milling, the plant area usually has a small height. But cultivation is carried out when the plants reach significant growth, and their breakdown at this stage can result in the death of the vegetable crop.
Medium-sized discs can be universal, with a diameter of 20-25 cm. At the same time, it is necessary to provide for a universal type of attachment to each type of attachment.
Accessory equipment for walk-behind tractor
Among the necessary improvements to the walk-behind tractor in the form of attachments, it is recommended to make, in addition to all of the above, the following elements:
- wheels with grousers for work on loose soil;
- lift;
- mounted bucket-blade for cleaning snow.
For wheel designs used as propellers for a walk-behind tractor on arable land, wheels with rubber tires are used. How to make wheels for a walk-behind tractor yourself with grousers will tell you experience and the ability to work with ready-made structures, for example, with steel wheels from car wheels.
For this you need:
- 2 steel discs from a car;
- corners 25x25 cm;
- electric welding;
- Bulgarian;
- tape measure and pencil.
The corner is cut into segments of 35-40 cm. The rims of the disc are marked into equal segments. It is best if there are 8 or 10. Marks are made and corners are welded in places of marks.
A do-it-yourself lift for a walk-behind tractor is better made from a piece of pipe with a diameter of 100 mm. The lift itself is made in the form of a roller on the bracket. If necessary, it changes its position and makes it possible to raise the walk-behind tractor on a support. In the normal position, the lifting shaft is in front of the machine and is used as a support roller when overcoming ditches and potholes.
It is recommended to assemble a bucket for a walk-behind tractor with your own hands if you plan to use it as a snowblower.
The bucket can be made:
- made of sheet metal with a thickness of 1.5-2 mm;
- hard plastic with a knife at the bottom of a metal strip;
- from plywood with a thickness of 8-10 mm or OSB board 10-12 mm.
The bucket is rigidly fixed to the walk-behind tractor frame. To facilitate the work, you can make a rotary device to change the angle of inclination of the cutting plane to the road surface.
In order for the bucket to work for a long time, a support ski is carried out in front of the bracket. This will make cleaning more secure. The cutting surface will be at a certain height above the ground and not touching the ground.
It is possible to improve home motor vehicles to fit your requirements without high costs. After all, attachments for a walk-behind tractor can be assembled independently, having done everything with your own hands.
