The advantages of the walk-behind tractor, such as low cost and simplicity of design, have reverse side medals. You have to follow him like a horse. With large volumes of work this is tedious.
Therefore, many owners of this device purchase or make their own adapter for a walk-behind tractor with steering control. This simple device turns the two-wheeled assistant into a real mini tractor.
At first glance, this is a complex engineering project that cannot be implemented at home. In fact, the technology is very simple both to operate and to manufacture.
An adapter for a walk-behind tractor is an addition to the unit that has its own wheel axle. When paired with a towing device, you get a complete four-wheeled vehicle. The question often arises: I made a homemade adapter, how to register with the traffic police? This is impossible.
Important! Such self-propelled vehicles are prohibited from traveling on the roads. common use. If you need to cover a long distance to the work site, use a carriage trailer to transport the walk-behind tractor.
The whole problem is that the walk-behind tractor does not have basic safety systems. Therefore, it is not a vehicle, per se. In addition, the open design (all mechanisms, including rotating ones, are a source of danger) in principle will not pass certification as a means of transportation. The same applies to factory adapters.
Conceptually there are two types of design:
The design is much simpler to manufacture, but it requires more effort to turn. And the geometry is somewhat worse. The turning angle and radius do not stand up to criticism.
Depending on the location relative to the power plant with the drive wheels, there is a front or rear adapter.
Advice! From the point of view of traction implementation, the preferable option is in which the driver sits as close as possible to the drive axle. Then its weight additionally presses the wheels to the ground, eliminating wheel slip.
Design elements:
Frame.
Ladder or spine. There are options for combining a walk-behind tractor frame and an adapter. In this case, the structure is calculated as a single element, with a newly manufactured pedestal for the engine and transmission.
Suspension.
As a rule, without elastic elements. Big choice structures – pavement, axial, portal, rotary.
Portal for attachments.
Manufactured with the adapter positioned in the rear. When positioned at the front, a walk-behind tractor portal is used. An option for mounting the blade is possible.
Hitch.
The most critical element of the design. Must provide reliable connection with a walk-behind tractor and vehicle stability. If there is steering, the hitch is rigid; if the rotation is carried out by changing the angle of articulation, it is mounted on a horizontal hinge. Can be performed with two degrees of freedom: rotation and twisting.
Workplace driver.
It is built taking into account driving safety, and can be equipped with duplicate controls for the walk-behind tractor.
Steering (in case of rigid coupling).
You can take a ready-made one, for example from a VAZ classic. You can make it yourself. Taking into account the peculiarities of movement, a homemade adapter with a steering wheel does not necessarily have to meet any control safety requirements.
How to make an adapter with your own hands without steering
Design with a hinge joint that acts as a steering control. The driver is placed on the adapter, turns are carried out by changing the hitch angle.
For production you will need:
- Profiled pipe measuring 30-50mm or slightly larger, depending on the power of your walk-behind tractor;
- Channel of similar size;
- A pipe with thick walls, or better yet, a steel circle with a diameter of 30-40 mm, in which holes for the coupling device will be drilled on a lathe;
- Steel rods different sizes, for the coupling device - made of hardened steel;
- A pair of wheels with bearing axles or hubs;
- Bolts, nuts in assortment;
- A ready-made seat, for example from a city bus. Or the material for its manufacture - dermantin, boards;
- Welding machine (it is better to use electric welding);
- Bulgarian, powerful drill or drilling machine;
- Lathe, or the opportunity to order turning work;
- Primer, paint.
The dimensions of the adapter for the walk-behind tractor are selected based on the needs of the device. Special conditions no symmetry, length homemade device may exceed the size of a walk-behind tractor.
Before starting work, you should draw a drawing of the adapter.
The frame can be higher or lower than the axis of the walk-behind tractor, it’s not a big deal. The main thing is to ensure that the structure is horizontal. Advice. If possible, place the landing site as low as possible for stability.
The wheels do not have to be placed on the axle, best option– portal suspension, it will provide sufficient ground clearance. Elastic elements are not installed, so it is better to choose tires with a high profile for shock absorption. Make sure that the wheels are aligned and that they are installed parallel.
How to weld an adapter without using factory equipment? If you do not have jigs to properly fix the frame elements relative to each other, use any flat surface. For example - chipboard sheet.
Structural elements are laid out on it, and welding is carried out in one plane. The frame is then turned 180° and the other side is welded. Then you can finish the side seams.
Important! Grinding welded joints done after all seams are ready and checked.
The most important part is the coupling device. This is a hinge that works in two planes. The vertical axis is for turning, the horizontal axis is to prevent diagonal hanging on rough terrain.
Complex design on bearings is not necessary, but it is more difficult to make than making a front adapter with a rigid coupling. The bushings should have minimal play and should be lubricated regularly.
The seat is placed in such a way that at any angle of rotation of the steering wheel, your back does not come off the backrest. Remote controls are not required; they are equipped only with an adapter with a steering wheel for a walk-behind tractor, where power point located behind the driver. You can place control levers for various land cultivation devices on the side of the seat.
On the rear cross member of the frame there is a bracket for attachments. Since you are sitting with your back to them, control will be difficult. This problem can be solved by upgrading your hiller or plow. It is necessary to add several rods and make a device to change the height of the working tool.

Alexey Well, you shouldn’t play sports. The frame is welded on a slipway made of square or rectangular section, the wheels can be picked up from walk-behind tractors, the steering mechanism is made from spare parts from mini tractors. In general, everything is not difficult if you really want to.
Stanislav Kart or buggy? There is no steering mechanism on the map - just rods and levers!

The walk-behind tractor, of course, simplifies all work in the gardens, but if you touch large plots then walk and drive it long time very tiring. For this reason, many owners of this equipment convert it into a kind of mini-tractor. Many people design incredibly convenient and practical devices by attaching an adapter with steering control to the walk-behind tractor. Now we will share with you how this can be done and what is needed for this.
How to make a homemade adapter for a walk-behind tractor?
At first glance, the design of such a device may seem very complicated, but if you figure it out and approach the matter with all responsibility, then making such a mechanism will not be difficult.
To create an adapter for a walk-behind tractor, there are 2 types of mechanism design:
- Steering.
- With movable joint.
Front Steering Adapter
To make it you will need a steering mechanism from any vehicle. The best option for use there will be a steering column from a tractor or truck. The essence of such a mechanism is that the steering bipod will protrude coupling device, thereby connecting the adapter to the walk-behind tractor.
One of the steering adapter assembly options is based on a ball base, which will make the hitch independent. But it’s better to make a separate coupling between the walk-behind tractor and the adapter.
And the steering itself can already be made on the basis of levers, or you can also use a steering bipod.
In this design, a steerable pair of wheels can be located both in front and behind the vehicle itself. Control of such a device is simple and very convenient.
Movable joint design
Such a mechanism is much easier to make. The only inconvenience of this whole design is that you will now have to put in a little more effort to turn.
What does this mechanism consist of:
- Frame. Can be combined with an adapter. Then such a design becomes unified and requires the manufacture of a new pedestal for the transmission and engine. You can also use a spine or ladder frame.
- Suspension. It can be different: axial, portal, rotary, bridge.
- Hitch. This is the main element of the entire mechanism. It is responsible for the stability of the device and ensures its reliable connection. To perform it, 2 degrees of freedom are used: twisting and turning.
- Portal for attachments. Manufactured in case the adapter is located at the rear.
- Steering (with rigid coupling). Of course, it will be more convenient to take something ready-made, but you can do it yourself.
- Driver's seat. It must be done taking into account driving safety.
Features of a walk-behind tractor with steering control
- no need to waste your energy walking behind a walk-behind tractor;
- the traction potential of the equipment is fully realized;
- such a mini-tractor becomes even more functional;
- Now, in order to cultivate an area away from home, you do not need to transport the walk-behind tractor separately;
- convenient and lightweight control; Now you don’t need to hold the entire weight of the device in your hands.
Adapter steering has both advantages and disadvantages. Among the main advantages are:
- the ability to quickly disassemble and assemble the structure;
- the controls do not change significantly during the alteration;
- good weight balance along the axles.
But among the disadvantages it is worth highlighting the worst stability, due to the movable coupling.
In any case, if you attach an adapter with steering control to the walk-behind tractor, such a unit will make your work easier. So try to design and cultivate the land with pleasure.
Typically, steering on a homemade mini tractor is required in order not only to improve the equipment, but also to facilitate a whole range of agricultural work. The walk-behind tractor in the form in which it is sold does not always make, for example, the plowing process easier. Therefore, creating a convenient mini-tractor is actual question for most summer residents.
Such homemade products allow owners of small plots to save money a large number of strength and money. Not everyone can afford to buy a ready-made tractor. The investment will not be worth it. But any person who knows how to hold a wrench and read blueprints can build such a technique.
Working drawing, preparation of tools and parts
The first stage of work often causes confusion. There are masters who do not have special education. However, they are able to create a masterpiece from a pile of scrap metal. They keep the entire assembly process in their heads and don’t fully know what they will achieve.
A professional approach always requires a drawing. It allows you to carry out the work step by step and understand in advance what parts you need to purchase. Therefore, it is better to sketch out a drawing and assembly diagram.
Almost everyone has the tool that they will need in the process. You need to prepare:
- drill;
- a machine with a cutting wheel, popularly called a “grinder”;
- electric welding machine;
- wrenches of different sizes.
In principle, assembly can be done in any way. If welding machine no, and you won’t be able to find it, you can attach the entire structure with bolts. It is necessary to prepare drills, electrodes, bolts and nuts. In addition, grease or oil for lubrication will be useful.
The creation of the steering system is based on the principle that is used in domestic VAZ or GAZ-53 cars. You can take a ready-made system and customize it to size. Usually it is necessary to shorten the shaft. The car can also be controlled using steering rods. The gearbox must be mounted on the frame and facing the operator. The brake is a hydraulic drum brake. Along with the hydraulic system, you need to buy a pump that will ensure proper movement of oil through the system. Before starting work, it is necessary to determine what load will be on the mini tractor and what the engine power is.
Assembly and adjustment of equipment
Steering allows you to move the tractor in a certain direction. In general, the entire system consists of a steering mechanism and a steering gear. There are two types of mechanism:
- worm;
- rack and pinion
The worm type is most often used for tractors, since it makes it easy to overcome uneven roads and has a significant number of advantages. However, there are also disadvantages. The biggest of them is a large number of parts and assemblies. Over time, backlashes form, which are difficult to eliminate. Rack and pinion mechanism simpler and more popular today.
Work on the steering begins with correct installation seats. The knees of the seated driver should not rest against the steering rods. Sometimes when creating a homemade tractor, the handles of the walk-behind tractor remain as steering controls. They are convenient, but only if the movement is carried out only forward. Reversing is difficult. This is why it is recommended to install a steering wheel. If the system is controlled using the steering wheel, it must be adjusted in height.
To make driving a mini tractor not so difficult, hydraulic cylinders are used. You can't make them yourself. It's better to buy a ready-made system. There are devices on sale that are designed specifically for agricultural machinery.
When creating the steering of a homemade mini tractor, use the steering column from a VAZ-2106 car or from any other car. The column is bolted to the steering rods at an angle of 45°. It is important to consider that the dimensions of the steering rods and columns do not always match. The problem can be solved by welding, welding on additional paws. The traction wheels should be at right angles to the wheels. After all the work, we adjust the wheel alignment.
In general, the design can be simple, without springs or other reinforcements. Because there is still no heavy load, like on a car. Sometimes the mechanism uses a steering wheel swivel assembly, a ball joint and steering knuckles.
Pedals required for full operation:
- clutch;
- brake.
The position of the pedals, height and direction also need to be adjusted. As a rule, if these are old parts of a VAZ car, they are located high when mounted on a mini tractor. It is not comfortable. But the cables for the pedals can be taken from an old scooter.
In the process of creating a small tractor, all elements need to be adjusted to the adapter or, as they say, made to suit yourself. Parts, especially those that carry a load, must be burned through welding at high amperes.
You can figure out how to attach the steering column yourself, based on the specific design of your walk-behind tractor.
It’s better not to come up with too clever designs and keep everything simpler.
Homemade tractor equipment, manufactured on the basis of walk-behind tractors, is equipped with a front steering axle. To create the steering control of a homemade mini tractor, mechanical and hydraulic components from serial equipment are used.
How to make a steering wheel for a mini tractor
Steering is designed to change the direction of movement of the vehicle. You can make your own control for a mini tractor based on mechanical worm and rack and pinion types. There are designs built on the basis of hydraulic mechanisms operating from a separate gear-type pump. The power transmission to the pump shaft is carried out from the toe of the engine crankshaft or from the through shaft mounted on the gearbox.
The most common is a worm-type drive, which includes a number of components:
- steering wheel;
- a column with a shaft mounted inside on bearings;
- gearbox (from “classic” passenger cars VAZ, Moskvich or GAZ, it is possible to use units from UAZ cars);
- rod going from the gearbox to the rotary hub of the front axle;
- a connecting rod that ensures synchronous rotation of the front wheels.
When using a rack and pinion gearbox, the kinematic diagram is simplified. The rack is connected by steering tips to the rotary hubs. Drive length adjustment is carried out threaded connection, secured with a separate nut. The use of such a gearbox requires accurate calculation of the installation location. For homemade equipment A rack and pinion gearbox from an Oka car is used.
Tool drawing and preparation
To create a steering control you need technical documentation, according to which components are selected for future design. Available in the database are used as the initial base. open access blueprints. The documentation will need to be modified in accordance with the dimensions and design of the existing mini tractor frame. After purchasing the spare parts needed for the steering, you can begin selecting the tool.
The minimum tool kit includes:
- tool ruler and tape measure;
- calipers;
- metal scribe;
- a hand drill with a speed controller and a chuck for clamping a drill with a diameter of up to 15 mm;
- electric cutting machine (“grinder”);
- welding machine (it is possible to use a small-sized inverter-type installation) and a set of electrodes;
- kit wrenches or heads;
- discs for cutting machine;
- metal drills;
- pliers;
- hammer (to remove scale);
- file (for grinding off sharp edges).
