How to make a single-axle tractor with a cart with your own hands
The single-axle tractor is one of the most useful and inexpensive technical devices used when working in homesteads and gardens. It is used not only for tillage and harvesting, but also for transporting hay, fuel and other heavy objects. The standard unit does not involve a trailer, but every person who understands at least a little bit about the device and the principle of operation of mechanisms, can make a cart for a power tiller with their own hands. Its design is quite simple.
To begin with, you need to refer to the drawings of the cart and sketches, according to which the production will be carried out. It is necessary to think about what will be the carrying capacity, dimensions of the device, and their compatibility with each other, focusing on the mechanisms made at industrial plants.
Making a self-made cart for a motor-block will save a lot of money, without spending much effort and time.
How to make a cart for a power tiller with your own hands
High-quality tillage is not a simple matter, it will require not only incredible labor, but also certain skills. Relatively recently labor was completely manual, today it is possible to automate a number of processes to achieve even more impressive work efficiency. Below we suggest considering how you can make a quality and reliable cart for a motor-block with your own hands, equip it with everything you need.
The cart variations for this kind of equipment depend directly on the ability to transport a particular load.
- Simple single axle dolly. Maximum lifting weight up to 70 kg. Its design will be simple and inexpensive.
- Bogie for power tillers with carrying capacity up to 110-120 kg. The most universal version for use in the farm.
- Trailer for transporting weights over 120 kg. The design becomes more complicated, the cost of material for the frame and cladding increases. This option is more expensive, but the capability of the cart is greatly increased.
If the power of the equipment does not exceed 5 liters. с., optimum dimensions of the trailer in length and width are 1.5 and 1 m. When the body parameters are calculated, piece the required length from profile pipes and weld the frame from them. The structure is sufficiently rigid, so there is no need to install reinforcing elements in the corners. To obtain a straight and quality joint over the entire length, you should work on a flat surface, the best way. with an electric arc welding.
Body assembly and painting
The sides of the trailer are framed with 25-30 mm profile. If there is any rust, remove it mechanically and then cover the surface with a rust inhibitor. Metal for the body must be without any traces of rust. If there is corrosion, it is removed mechanically, and then the surface is coated with a rust primer. Fit the body on the frame. If all dimensions are the same, go through the test assembly. Then it is disassembled, the body is set aside, and the frame is covered with oil paint. No unpainted elements should be left anywhere.
Useful tip: if you can, it’s better to use polymer-based paint. You should not neglect the primer in this case, because the treated surface has better adhesion. Powder coatings are more resistant to abrasion, and surfaces coated with conventional oil compounds need to be refreshed at the beginning and end of the season.
The body decking is also painted and then reinstalled. Fix the joints with fasteners, then paint the protruding parts of bolts, so that these places do not corrode. If dried paint has come off in places, these areas need to be repainted. Make a drawbar from the thickest pipe.
Since the design involves a tilting bogie, special axles are made in the middle of the bottom. To ensure that the hinged mechanism does not jam when lifting, it is necessary to maintain alignment. Amplifier bushings are fixed with a 5-6 mm thick plate. The same parts are welded to the coupling device (drawbar), which serves as a base frame. Assembling a swivel joint with your own hands requires great precision. A stainless steel circle 5 cm in diameter is used as the base. Studs also made of hardened steel. Since the intensity of movement of the joint is low, you can do without bearings, the main thing is to regularly lubricate the mechanism.
Steering construction is fastened on a coupling device. the horizontal joint is made detachable, and the sleeve from it is bolted to the drawbar. The steering knuckle is placed vertically on the trailing pin.
When everything is ready, a test loading is carried out to check that there are no problems when running, turning, starting, stopping, etc. д. If the equipment with a trailer works properly in all modes, the design is ready for use. If the power of the power tiller allows it, the cart can load from 300 to 700 kg.
A self-made trailer is several times cheaper than a factory-made one and will serve for decades. The main thing is to use quality materials, to observe dimensions and carefully perform the assembling.
The trailer for a power tiller used in the farm does not have an extremely complicated design. Because of this, having an electric drill, grinder and welder at hand everyone will be able to make such a device with their own hands. However before assembling you will need to study the scheme that will prompt the order and place of assembly of trailer parts. In addition to the study of the scheme before making it is extremely important to study the characteristics of the future trailer. It is possible to be guided by factory-made models.
One of the most important parameters of trailers is their load capacity. Factory-issued carts for power tillers can carry luggage, with a total weight of 250 to 1000 kg. it all depends on the class of power tiller, with which the trailer will be used. In terms of these parameters, the commercially available trolleys are divided into light, medium and heavy-duty designs.
To be used in combination with heavy farm implements with more than 10 liters horsepower. с., two-axle bogies with two or more axles of a width of approx. 1.5 m and a length of 3 m are used. Such a trailer for a single-axle tractor is capable of carrying a load of 500-1000 kg. A similar two-axle design can also be equipped with benches to transport a small group of people.

Medium carts are used primarily for power tillers with 5-10 liters horsepower. с. These trailers are single-axle structures with dimensions of 1.21.6 м. Such a cart on a single-axle tractor can handle the transportation of luggage with a total weight not exceeding 500 kg.
Motorcycles, up to 5 liters. с. is best equipped with lightweight single-axle trailers, up to 1.2 m long and up to 1 m wide. The maximum weight of luggage carried on these carts is 300 kg. The lightweight wheelbarrow is considered the easiest to make on your own, and requires minimal materials, effort and time.
The second important factor is the height of the available sides. Light and medium factory carts are equipped with walls, the height of not more than 35 cm. bigger in size trailers have sides up to 60 cm high. Every trailer model, regardless of class, has one collapsible wall. usually on the rear side. Such a skirt significantly simplifies the process of loading and unloading of transported luggage.
In order to prevent the trailer from accidentally rolling on a slope and to stand firmly on the road, a simple braking system is provided for it. How to make brakes on a tractor-trailer? It is best to use a parking structure from a car or motorcycle and fix the mechanism near the driver’s seat with bolts.
As in any vehicle, the brake system is a factor in road safety. You can make your own brakes using a cable, a pull rod, and a drum:
- A drum is attached to the hub of one of the wheels.
- They take a brake disk and weld a small piece of pipe to it.
- Slide the mechanism onto the axle.
- the brake pads are fastened to the axle with a cable to the lever near the driver’s seat.
Brakes are not usually installed on two wheels. One parking brake for the trailer to the tiller is enough.
How to make a disc plough on a single axle tractor?
The disc plough is a very useful tool that allows you to prepare even furrows for planting potatoes and other tuber crops. Before starting to make the plough, read the blueprints. They will help you control the assembly process and prevent errors. The procedure for making a disc plough for a single axle tractor is as follows:
- The base of the plow is the support angle. For its manufacture, use an equilateral angle, the shelves of which in the cold state should converge at an angle of 70 °;
- Weld the sock to the angle. Then weld the heel through the stop bar;
- Fix the slats on the supporting bracket with loops. The distance between the angle and the jaws must be such that when the jaws are opened their end sides do not rest against each other;
- Weld the turning element to the fixed angle so that the bearing part of the element is perpendicular to the angle.
Finally, adjust the plow’s cheeks. To do this, fix each of them in a vice and adjust so that as a result they are bent in the opposite direction from each other.
The cart for the power tiller can carry a load of 400-450 kg plus the weight of the driver. It easily carries six or seven bags of potatoes without overloading.

They are taken from the sidecar together with the hub assembly. Both ends of the axle are turned to fit the diameter of the hub bearings.
Hitch to a power tiller
Crab and power tiller hitch is provided by console. The upper part of it follows the contour of the tool carrier because it is attached to the standard attachment bracket of the power tiller. The steering unit is mounted around the lower part as an axle in two RUP bearings. The space between the RUPs is filled with grease and closed from the outside with dust covers. For heavy-duty applications, the connection between the bogie and the driver must be a swivel joint.
The drawbar is inserted into the tubular body of the longitudinal joint and secured by a thrust ring. This design makes the bogie’s wheels independent from the wheels of the tiller, which makes the tiller’s handling much easier when riding over rough terrain.
