How to make a plow for a mini-tractor with your own hands?

The plow is a tool designed for plowing hard soil and has been used by humans since ancient times. The intended use of the plow determines its technical and quality characteristics: the design of the frame and cutting element, fastening mechanisms and stops, the material of manufacture and its thickness.

The plow for its purpose is of several types:

• manual - for plowing soft land of a small area;
• equestrian - it is used in situations when it is necessary to cultivate land, access to which is limited for special equipment;
• with cable traction - helps to cultivate the soil in hard-to-reach places, for example, in the mountains or in a swamp;
• hinged - works in conjunction with special equipment, allows you to reduce the turning radius during sequential plowing;
• trailed - general purpose plow.

The mentioned types of plows, in turn, are subdivided into the following subspecies:

• single-hull;
• double-hull and more;
• disk - revolving;
• rotary.

A common configuration for a DIY plowing tool is shown in Figure 1.

The main parts of the body structure have the following details:

• chisel - overlay on the cutting part;
• ploughshare - removable "knife";
• wing, chest and blade feather;
• shallow - cuts corners from soil layers;
• rack - fastening element.

Modern technologies allow you to make a plow with your own hands. You can design it according to your drawings or modify the finished one to suit your needs. Self-made tools have a number of advantages and characteristic design features.

A self-assembled plow is a tool that meets target needs and has a low cost. For its assembly, you can use the materials available, as well as parts of the structures of other agricultural units. The latter can be taken from old agricultural workshops, ferrous metal collection points, and other similar places.

A homemade plow is easy to orientate to suit your needs. It is possible to adapt it for different types of soil, draft mechanisms and even for the functions of processing agricultural crops. Your own plow can be made taking into account the power and productivity of tractor equipment, which will allow you to achieve the highest efficiency and reduce destructive loads on the plowing tool.

The cutting element of this plow can be interchangeable and made / sharpened independently, which significantly reduces the cost of maintenance of the mechanism. In case of self-production, it becomes possible to vary the intended use - the introduction of the function of replaceable elements: nozzles, fasteners, parts of the body and frame. This allows you to perform work of a combined nature, for example, plowing and mowing bush.

When making your plow, you can pay special attention to the choice of materials and their quality. This is one of the key advantages of self-made assembly, since when buying a plow from a store, it is difficult to be sure of the quality of the metal used to make a factory unit.After purchasing a store model, you may need to further refine it or replace some low-quality structural units.

Making a homemade plow for a mini-tractor requires a basic tool:

• welding inverter;
• grinders;
• drills;
• vice.

And an additional tool, the list of which is determined by the design of a specific mechanism and the conditions of its production.

List of materials that you may need:

• high-strength thick-section sheet metal;
• metal corners and plates of sufficient thickness;
• bolts of various calibers;
• additional names (washers, bearings, springs), determined by the characteristics of a particular design.

In order to facilitate the process of assembling a plow for a mini-tractor, you can go through the reconstruction of another tool of the same name used in conjunction with draft objects: a horse plow or a skimmer from the plowing mechanism of a large tractor.

Assembling the required unit requires drawing up the correct drawings. Their presence will ensure design optimization, a reduction in the number of component parts, simplicity and quality of assembly.

The drawings should indicate the dimensions of the elements that are closely related to the dimensions of the mini-tractor, the properties of the cultivated soil. During the manufacturing process, it is important to adhere to these parameters.

At the design stage, it is worth drawing separately each detail that has an irregular shape, in compliance with the actual size. In the future, from such drawings, it will be possible to create a template for transferring the image of a part to a metal workpiece. Some variations of the plow drawing are shown in Figures 2 and 3.

Consider two options for making a plow for a mini-tractor.

This configuration of the plow, coupled with a mini-tractor, is considered the easiest to manufacture. All the work on the reconstruction of a horse plow is reduced to adapting a frame to it, which has a special fastening mechanism, equipping it with a wheel (if necessary) and a weighting agent.

The equestrian plow consists of a body and a double-sided frame, which serves as a mechanism for attaching to the animal's harness and as a means of controlling the plowing process. Its simplest configuration is shown in photo 4.

In this case, it is necessary to reconstruct the fastening part of the horse plow into the one that will be installed on the mini-tractor with the least effort. This process can be simplified by making a towbar for a tractor attachment. A copy is shown in photo 5.

The towing hitch is easy to manufacture. The wide plate, which has two horizontal holes with an internal thread at the edges, is complemented by a protrusion in the middle, into which a forefoot ball with a leg is screwed / welded. In the center of the plate, an L-shaped part is attached, which serves as a locking mechanism for the plow frame, put on a towbar. The plate is placed between the two "ears" of the tractor mount, fixed with four bolts.

The modification of the horse plow shown in photo 4 is equipped with a special wheel. It serves as a stop for the frame of the structure, with its help, you can adjust the depth of entry of the plow into the soil.

The adjustment is carried out using a simple mechanism - a threaded bracket into which a clamping bolt is screwed. The wheel stand can move vertically inside the shackle. The bolt fixes it in the desired position. This design allows, if necessary, to move the shackle along the plow frame.

The wheel itself is made of a metal rim, spokes and an axle drum.For its manufacture, you can use a metal tape 300x50 mm, reinforcing bars, a piece of pipe with a diameter equal to the diameter of the wheel axis.

The metal tape is bent in the form of a hoop, its edges are welded together, the weld seam is ground with a grinder's grinding or cutting wheel. A piece of pipe equal to the width of the tape fits into the center of the circle. The distance from the rim to the outer surface of the pipe - drum is measured. The reinforcement spokes will be equal to this distance. The resulting blanks are welded together. To improve the rolling characteristics of the wheel, a bearing of the appropriate diameter can be welded into the drum. This will reduce friction and reduce the load on the wheel axle.

The described plow design can be operated in two ways. In the first case, you will need a second person who will operate the plow from behind, adjusting the furrow line. In this case, the "manager" exerts pressure on the frame, which is necessary for a sufficient immersion of the ploughshare into the ground.

In the second case, the presence of an assistant is optional. The plow becomes heavier and moves by itself. The weight can be a piece of heavy metal or a stone enclosed in a frame. The weight is placed on the edge away from the tractor. In this case, the pressure on the share will be maximum for the available weight. To prevent the load from overturning the plow, it should be secured from the underside of the frame.

When operating the plow without a second person, the furrow curvature factor should be taken into account. The simplicity of the described design assumes the "floating" of the plow from side to side. To eliminate this problem, it is necessary to equip its "rigid" coupling with the tractor. In this case, the traction mechanism will steer the furrow strip.

Skimmer is an element of a tractor plow used for cutting off the top layer of soil in the process of plowing it. Photo 6.

Its shape is similar to the working body of a plow share, and its size is half the size. This fact allows you to effectively use the skimmer as a plow for a mini-tractor.

During the design process, you will need to weld a frame that will hold the skimmer and attach to the tractor hitch, and also equip it with a stop wheel.

When creating drawings of this design, it is worth considering the power of the tractor, the condition of the cultivated soil, the amount of future work. If a large area of ​​land is to be plowed, two skimmers can be used on one frame. In this case, the plow will turn out to be two-body. This is necessary in order to reduce the load on one share housing and reduce its wear.

The process of assembling a structure, its installation on a tractor is similar to the reconstruction of an equestrian plow. A frame of a similar configuration, a wheel, attachments for the plowshare stand and the entire structure to the towbar are made. A weighting device or control knobs are mounted for manual furrow correction.

During the operation of a homemade plow, appropriate safety measures must be observed. Among them, the most important points can be highlighted.

• at the moment of movement of the plow along the furrow, its height adjustment, cleaning the wheel and ploughshare from the ground and other manipulations associated with the participation of a person are unacceptable;
• all connection nodes must be securely fastened - backlash is unacceptable;
• it is necessary to carry out timely cleaning of mechanisms and sharpening of cutting elements;
• perform all operations only with an immobilized plow with the tractor turned off.

To ensure labor safety, it is important to perform work that meets the technical characteristics of a particular agricultural machinery. Excessive loads can lead to rapid wear, damage to the unit and damage to human health.
