To make a universal joint, you need as flat horizontal surface as possible. a workbench or desk. The scheme of making a trailer (hitch) for a power tiller is as follows:
- Mark up the parts on the workpiece according to the drawing.
- Use a drill or boring machine to make the holes as marked. Make sure they are accurate by using a caliper and the bolt (stud) with which they will be attached. Achieve the optimum diameter of the hole with no backlash or jamming of the fasteners. Serve the holes with a countersink, which will make future work easier and protect you from injury.
- Weld joints. It is best to use electric welding, which heats the joints without damaging the performance of the metal.
- Assemble the piece. Join the bracket and the channel with bolts. If your design has an adjustment mechanism, fix that too.
Important! Fixing elements, by means of which the coupling is fixed to the single axle tractor through the holes in nodes, must be of the same quality and strength as the part itself.
Once again, let us remind you that the part is made to maximize the versatility of your power tiller. With the optimum hitch, any attachment or trailed implement, including plow, harrow, duckfoot, potato planter, various types of mowers, trailers and any other implement can be easily and efficiently operated over a long period of time. And since the attachment elements on different equipment can vary, which often complicates the possibility of their compatibility with the power tiller, it is the successful design of the coupling and the possibility of its adjustment solves this problem.
Once the part is assembled, it is important to attach it correctly. The rules of installation are quite simple, but it is important to stick to them. Connecting the device to your power tiller is very simple: align the holes in the hitch and hitch and secure them with bolts or pins. The radius holes allow you to adjust the position of the attachment while you are working. After installation, tighten the threaded fastening elements of the unit with the power tiller. Then the coupling equipment is connected.
After the initial locking of the attachment, the final locking is carried out immediately before starting the work. Loosen the adjusting components (screws), find the optimum level of locking and then tighten with wrenches. Depending on the design, a removable threaded axle can be mounted on the bracket, into which the M16 screw is screwed.
And you should make a few more recommendations. To preserve the working qualities of metal and increase the durability of the part after its assembly, it is desirable to perform a coating with an anti-corrosion composition or paint for metal.
Given the possibility of adjusting the design in different ranges, you can set the radius grooves and fix them to zero. After starting work, during the first few meters observe the coupling carefully and make further adjustments, if necessary. The presence of the adjustment lever allows you to change the fixation level and fix the attachment for greater or lesser depth of ploughing.

The tiller is one of the most efficient helpers for planting potatoes. This hitch is used on many types of power tillers and helps to bring the process of potato planting to automatism. Potato tillers to the tiller must be purchased separately, but some craftsmen prefer to make the equipment with their own hands. Below we will consider how to make homemade oculars, and what will be needed.
Assemble a homemade trailer for a power tiller
Proceeding to the implementation of the project, the master self-maker needs:
- Create a working design or drawing (blueprint);
- Prepare the material for the frame and other basic units;
- prepare the workplace;
- To carry out the marking of the main elements of the design of the trailer;
- to make the lining and alignment corners;
- assemble the templates for the parts;
- To make a fitting of the purchased whole units to the elements of the design.
The necessary tools and materials
To carry out the work it is necessary to prepare all the necessary tools:
- welding machine;
- Angular grinder with a set of cutting and abrasive discs;
- Measuring tools. tape measure, metal ruler, protractor, angle, marker and chalk, metal draftsman;
- hammer, chisel, pliers;

Wheels need to pick up immediately with hubs, it will facilitate the further assembly of self-made.
Trailer frame is an all-welded construction in the form of a frame grid made of square tube. Traverses from a square 25×25 mm form frame cross members, and longitudinal members are made from a pipe 60×60 or 60×30 mm. All structural elements after marking are cut and laid out on a flat surface, the joints are welded with small seams, each joint of the elements is checked with a square. After the chassis has been assembled, all parts are finally welded together along the perimeter of all planes. The frame is painted after the surface has been treated with metal primer.
The undercarriage is based on a beam with hubs at the ends. Studs are docked together so that they form a square. The joints are welded with a continuous seam. Wheel hubs are installed on the axle ends and welded.
axle is carefully assembled by checking that the wheel flats are parallel to each other. The frame and beam are joined together using leaf springs, with the leaf spring ends inserted into the welded-on brackets on the frame and the beam pressed against the center of the leaf springs using a suspension eye.
Undercarriage mounted on the frame is additionally checked for stability against tipping. As in the car, the spring group of the axle must have rubber bushings in the frame mounting bracket.
Body, frame cladding
The platform is measured in relation to the grid, so that the allowance is left to fasten the posts of the boards. The front and side boards are set permanently, and the rear board is made removable on door hinges.
The sides of the trailer have a frame construction from 25×25 mm angles. The angles are welded butt-welded, the seams on the inside are deburred to level the plane of the metal.
Removable tailboards are assembled in the following sequence:
- sideboard frame;
- The galvanized iron sheet is adjusted to the size of the frame;
- cut out the blades of the board and fasten them with rivets through the corner.
The bottom of the body is made of a sheet of 2mm sheet metal, inserted into the frame and welded over the perimeter with a small seam every 3-5cm.
Installing the sides starts with installing the front board, then the side boards are installed and welded together.
Rear board is fixed last. first the hinges are marked and welded, and then the latches.
Other construction details
After the frame and body are assembled, a folding seat. a wooden bench placed on top of the front board with support on the sides. is installed.
As the braking system of the trailer it is recommended to use elements of the braking system of the car, the hub and wheels of which are used in the construction. For reliable operation of the braking system it is recommended to provide an additional lever lock.
How to make a hitch for a power tiller with your own hands we explain in detail
One of the important components that ensures a reliable connection between the trailed equipment and the power tiller is the hitch. There are different types of coupler assembly. However, the most commonly used is the U-shaped coupling unit of the power harvester. This component is either industrially or self-made. If the coupling to the power tiller is made with your own hands, it must be strong enough to withstand heavy loads.
If the capacity of the equipment does not exceed 5 liters. с., the optimum length and width of the trailer are 1.5 and 1 m. When the body parameters are calculated, they cut off pieces of profiled pipe of the desired length and weld the frame from them. The design is quite rigid, so no reinforcing elements are needed in the corners. To obtain a straight and high-quality joint along the entire length, you should work on a flat surface, best of all. using electric arc welding.
Bodywork assembly and painting
The sides of the body are framed with 25-30 mm profile. Sheathing is assembled from sheet metal and then attached to the profiled pipe with screw joints. The metal for the body must be free of rust. If there is corrosion, it is removed mechanically, and then the surface is covered with a primer rust converter. Body fitted to the frame. If all the dimensions are the same, perform the test assembly. Then the bodywork is disassembled, put aside and the frame is coated with oil paint. You must not leave any unpainted elements.
Useful tip: if you can, it’s better to use a coloring agent on a polymeric base. Even in this case, the primer should not be neglected, because the treated surface has better adhesion. Powder coatings are more resistant to abrasion, and surfaces coated with conventional oil coatings should be renewed at the beginning and end of the season.
The body decking is also painted, and then repositioned. Fix the joints with fasteners, and then paint the bolt extensions to prevent corrosion in these places. If some parts of the dried paint has come off during assembly, they are repainted. Make the drawbar from the thickest pipe.
Since the design provides for a tilting cart, special axles are made in the middle from below. The alignment must be maintained so that the folding mechanism does not jam when being lifted. Fix the bushings using 5-6mm thick plate. The same parts are welded to the drawbar as the base frame. Assembling a swivel joint with your own hands requires great precision. A stainless steel circle with a diameter of 5 cm is used as the basis. Studs are also made of hardened steel. Since the intensity of movement of the joint will be low, you can do without bearings, the main thing. regularly lubricate the mechanism.
Fix steering structure on the hitch. The horizontal hinge is made detachable, and the sleeve from it is bolted to the drawbar. The steering pin is positioned vertically on the hitch pin.
When everything is ready, test drive and check that there are no problems when driving, turning, starting, stopping, etc. д. If the technique with the trailer works properly in all modes, the construction is ready for use. If the power of the power tiller allows it, it is possible to load from 300 up to 700 kg on the cart.
Прицеп, сделанный своими руками, обходится в несколько раз дешевле заводского, а служить он будет не один десяток лет. The main thing is to use quality materials, observe the dimensions and assemble carefully.
Choosing a hitch on a single axle tractor
Any attachment or trailed implement for a power tiller, whether it be a harrow, a dipper, a mower, a trailer cart or any other equipment, is attached by a hitch. If the basic part is not suitable, the owner has a choice. to buy a suitable one or make a coupling for a power tiller with his own hands. In any case, when determining which version of the unit will be able to best fit the tasks that the unit performs, you need to consider a number of points, including:
- The peculiarities of the motoblock or cultivator;
- The areas of application of the unit. The functions it performs;
- equipment to be aggregated with it;
- the need for versatility.
Based on this, you should carefully review the most commonly used designs and guided in the choice, based on the features of the one that is best suited in this case.
In this video you will learn more about the hitch:
Choosing a hitch on a single-axle tractor, it is worth taking as a basis the most suitable type of part. There are several types:
- Single/double. used when there are different attachment options depending on what is used and in what quantity;
- reinforced. is optimal for heavy machines, its distinctive feature is that it is more massive. it has a greater thickness and length, which allows additional equipment more deeply into the ground;
- adjustable. providing the ability to change the angle of the shaft, so you can adjust the level of attachment of attached equipment and thereby improve the efficiency of work;
- universal coupling. allowing aggregation with several models.
If the coupling to the tiller desired design is not available for sale or have any requests for it, to make it yourself is not so difficult, because it is a fairly simple device. Some craftsmen who prefer to make many accessories for the tractor unit with their own hands, make a design of a coupling for the drawbar-tube trailer, make it from a cardan, from a cross tube, from other improvised parts, left from various mechanisms. The owners of such devices note that to make such a unit is not particularly difficult, and they share their experiences and drawings of coupling for a power tiller.
About the knot
Its main task is to ensure a firm contact of the hitch and the tiller. There are several types of coupling. Nevertheless, the most popular type is the U-shaped. Such a universal hitch for a power tiller can be made by yourself or purchased as a ready-made hitch. If higher loads are planned, then it is better to make the knot with your own hands. This will allow for this aspect in the design.
As noted above, there are many manufacturers of power tillers, but it should be noted that the design of these devices, by and large, is identical: there are only small deviations in one direction or another. This is why you need a hitch that is versatile enough to be used on a variety of models, whenever necessary.
Types of couplings
These operations are carried out with the help of attachments. This is decisive for the dimensions and configuration of the single-axle drawbar hitch. It comes as a single and double. The first type involves hanging only one piece of equipment, the second. two. The choice depends on the area of the site and the volume of tasks to be performed during its processing. The more of them, the more sensible it is to have two guns on the tractor, and not one. The power tiller, for example, is a good match for a power tiller that not only cuts the weeds but also loosens the ground. This increases the tillage capacity of the power tiller.
As for the dimensions of the hitch, the reinforced variation (with increased length and thickness of the metal used in production) is installed on heavy power tillers. It is designed for wide-area farming. You need an adjustable coupler to connect the power tiller with a plow or a planter. This combination makes it possible to set the best angle of attack and turn and the desired working width. There is a separate type of coupling. the swivel coupling. Their use makes it possible to lift implements. The tilled soil is not disturbed.
Based on the above, it is best to make a universal coupling for a motor-block, which provides regulation and the ability to lift the attached equipment with your own hands.
There is another classification of devices. according to the mounting area. Rear hitch is used for mounting of the rear-mounted equipment, and the front hitch is designed for the front-mounted equipment.
Universal drawbar eye assembly sequence
After all the necessary equipment has been prepared, proceed to the study of the drawings. The drawings should indicate the exact dimensions of the parts and their place in the overall construction of the hitch.
The correct order to assemble the coupling mechanism is as follows:
- First, you need to take two identical U-shaped brackets, and carefully make small holes in them with a drill. There should be 6 holes in the first brace and 8 holes in the second brace for M12 type bolts;
- The housing is one of the most complex parts of the hitch. To make it as secure as possible, it should be welded from several parts. It is very important to make the right holes in the existing housing. There should be two threads in it, one M16 and one M12;
- Inside the body it is necessary to place the mechanism for adjusting the coupling position. A screw connected to the bracket and handle should be used to make the mechanism;
- The most complex element of the design is the handle, which consists of several small parts.
Most of the parts of the coupling for the used power tiller is simple enough to be turned on a lathe. If you have no experience in doing such work, you can order them from a lathe, or buy ready-made parts on the market.
Universal coupling for your power tiller with your own hands
The universal coupling fits most power tillers and trailed or hitched implements without backlash. To make the hitch is fairly simple, the main thing is to determine the tasks that it must solve, choose drawings and quality materials to ensure the strength of the node.
U-shaped trailer coupling for power tillers is suitable for most power tillers. The main point in creating a hitch is to match the size of the brackets of the motorblock itself and the hitch. The peculiarity of the device with the bracket is that the attached equipment, which is aggregated with it with the power tiller, takes the position for several centimeters below the bracket itself, so it must not be at the level of the cultivated ground.
On the Internet you can find many videos in which owners of motor blocks talk about the nuances of working with attachments, including how to make a hitch.
