Buying a walk-behind tractor as a necessary means of production has become a necessity for many, but for normal operation of the unit, you must buy a trailer as part of the kit. However, the proposed models do not always take into account the necessary features, and this is one of the reasons that many owners of such assistants prefer to independently design a trailer for a walk-behind tractor with their own hands.
To build a trailer for a walk-behind tractor yourself, you can do the following:
- trailer frame;
- body;
- axle and chassis;
- hitch.
Drawing of a trailer for a walk-behind tractor
To make the work easier, you need to purchase or use ready-made elements:
- passenger car wheel hubs;
- wheels assembled with tires;
- tow hitch for a vehicle.
What is a trailer for a walk-behind tractor?
The towbar to the walk-behind tractor consists of:
- body;
- wheels;
- wings;
- seats;
- drawbar;
- brakes
The ability of the body to withstand a particular load depends on the quality of the assembly. The cart must be made of durable material that can withstand the weight of the load and any weather conditions. In addition, it is desirable that it have folding sides for ease of loading and unloading. The dimensions must be roomy and match the power of the walk-behind tractor.
Wheels are used on carts: car wheels, motorcycle wheels, etc. The main thing is that the cart for the walk-behind tractor can withstand heavy loads.
Wide wheels are preferable, as this increases the vehicle's maneuverability.
There are wings on cars too. Serve as protection against stones and dirt from wheels.
All modern trailers are equipped with seats. Some craftsmen build a box underneath to store necessary things.
The drawbar is a triangle-shaped mount that connects the trailer to the walk-behind tractor.
Brakes will improve the process of transporting goods.
Trailed equipment for walk-behind tractors can be purchased from manufacturers of agricultural machinery, or you can make a homemade trailer for a walk-behind tractor. Let's consider both options.
There are many ready-made models for motor cultivators on the market. They have different sizes, weight categories, carrying capacity and cost. Their advantage is that they are assembled by professional mechanics according to pre-developed schemes. You don’t waste any effort or time on this. The disadvantages are, firstly, the search for a conscientious manufacturer that sells a quality product, and secondly, a high-quality product is not cheap.
The walk-behind tractor acts as a horse cart. It acts as a drive connected by a drawbar to the trailer. The following brands of walk-behind tractors are suitable for this purpose: Patriot, Ural, Cayman 320, Forza, Crosser, Foreman, Viking, Texas.
You can make a trailer for the Neva walk-behind tractor, made of durable metal. Load capacity of the body is 500 kg. The trolley has a brake drive, which makes driving easier. On the Internet you can find a lot of drawings of trailers for the Neva walk-behind tractor. They have a successful design with minimal consumables.
Among the ready-made models you can find a device with a dump truck function. The design is basically the same as on a conventional trolley, but with a modification that allows unloading by tilting the drawer. Although this model is more expensive, it is necessary on the farm.
The manufacture and assembly of the trolley is often carried out by the owners of walk-behind tractors themselves. There are a lot of homemade products, but they can be assembled according to one principle - a chassis on wheels, sides and an axle to connect the trailer to the walk-behind tractor.
From a VAZ-2109 beam
A trailer made from a VAZ-2109 beam is suitable for walk-behind tractors with high power - 10 hp. The structure will be quite heavy, so more traction power is needed. Such trailers have a large load capacity.
It’s easy to make a trailer from a VAZ-2109 beam with your own hands; just watch the training videos, which are available for free. You can also find drawings and dimensions of the structure; almost any one, with one or two axes, will do.
The beam will be used as an axle; a whole axle with wheels from a VAZ-2109 will be suitable for the rear axle. For the front axle, one beam will be enough; the wheels can be any. For large trailers, wide wheels are recommended to ensure maneuverability and stability.
The advantage of a trailer for a walk-behind tractor based on a beam from a VAZ 2109 is that there is no need to waste time on manufacturing additional components, especially if the entire rear axle is taken.
Required tools and materials
To ensure high-quality performance of trailer assembly work, prepare the following tools:
- apparatus for welding work;
- grinder for cutting material with a set of cutting wheels;
- tape measure and ruler, protractor and square;
- marking tools (chalk, ink, marker);
- impact tool (hammer), chisel and pliers;
- yew for fastening parts, clamps and clamps;
- electric drill with a set of drills of various diameters for working on metal;
- equipment for installing rivets in the trailer body.
To make a trailer frame, a square or rectangular metal profile, a small-diameter steel pipe, angles, and a channel are used. The trailer pallet is a steel sheet up to 2 mm thick. Bolts, nuts and rivets are used to connect parts of the structure. Springs and a beam are added to the trailer to attach the wheelset. Car wheels from Moskvich or Zhiguli are suitable as wheels.
Don't forget about the appropriate trailer tool
How to make a trailer for a walk-behind tractor with your own hands
Let's look at how to make a trailer for a walk-behind tractor with your own hands. It is important to be able to read drawings and diagrams, as well as have the skills to use certain tools.
A homemade trailer for a walk-behind tractor is made according to diagrams and drawings, which can now be found in large quantities on websites on the Internet. Before you get to work, you need to develop a drawing of a trailer for a walk-behind tractor. In addition, it is necessary to prepare all the small parts for fastening, tools and a welding machine.
The dimensions of the trailer for the walk-behind tractor must be clearly drawn on the diagram, each detail is marked and highlighted from different sides.
You need to assemble the trailer based on the power and dimensions of the walk-behind tractor. Equipment with insufficient traction power will not drag a heavy semi-trailer.
Having understood the diagram, you need to decide on the leading parts of the trailer. The basis is the frame and hitch for the walk-behind tractor trailer. These are followed by the frame, driver's seat and wheels (2 or 4 pieces).
They usually start with the main component of the cart - the frame, since it is on it that the entire load falls during the transportation of goods, so it must be extremely strong. The ideal option would be a ready-made axle with wheels, in which case you will not have to waste time and effort on additional settings. It is important that the materials are hard and not deformable. You can use pipes or a thick channel.
The simplest method is a trailer assembled from 60x30 mm pipes welded together to form a frame. A traverse (steel crossbar) is attached to them. Transverse pipes are attached from different sides, which in the future will serve as racks. For piping, pipes with a cross-section of 25 mm are welded to the posts, and at the end - corner supports.
It is preferable to weld the trolley parts together; bolted fastening is considered not very reliable and short-lived. To strengthen the cart, braces are added from below and a reinforcement is welded.
Once the supports are completed, they move on to assembling the body. Any materials are suitable for this: wood and metal, and a combined option is possible. It is advisable, of course, to make the base metal. For strength, it is preferable to make the bottom double. To make the sides attach better, corners are welded along the edges. For easy loading and unloading, the sides can be folded by placing them on a movable mount.
There is no need to choose very heavy materials, since the weight of the assembled trailer will overload the engine of the walk-behind tractor. The simplest body can withstand weight up to 500 kg, and this is enough for a small farm.
It is better to take wheels from used equipment; they already have hubs. The rods on which the wheels will be supported are prepared. It is desirable that the wheels are located directly under the sides. To attach the wheels, the rod is pre-sharpened to the size of the wheel bearing. Instead of a rod, you can use devices from a VAZ beam.
Design Features
Before assembly, during design, you need to pay attention to the following points:
- Connection methods. It is necessary to think in detail in advance about how the moving components and assemblies will be connected to each other.
- Manufacturing materials. You will have to decide what exactly the trailer will be made of.
- Seat type. It can be stationary or rotating.
You also need to decide on the type of connecting node. It can be bushed or bearing-mounted.
The presence of a seat is a distinctive feature of carts for walk-behind tractors
Tow hitch for walk-behind tractor
A trailer for a walk-behind tractor is useful on the farm, so it must be durable. The main load falls on the frame, which is the basis of the structure. The towbar also receives enormous loads. The service life of the structure depends on the quality of materials used to create it, as well as the method of fastening.
The trailer hitch for a walk-behind tractor can be purchased ready-made, or you can make it yourself. Drawings and dimensions are easy to find on the Internet, one example is in the photo:
The coupling mechanism can be made in different ways, for example, from a cardan, a cross, or a part in the shape of the letter “P”. The last option is considered by many to be more reliable. The towbar must be made of stainless steel.
Types and purpose of models of main structures of walk-behind trailers
The main types and models of trailers for self-made walk-behind tractors are classified according to the type of homemade body part design:
- one-piece structures;
- transformable structures with folding sides;
- tipper body types.
The one-piece design of the trailer includes a rigid, non-removable side body. Due to the rigidity of the design, the trailer allows you to transport cargo both in bulk and in packaged form. The body has a large rigid frame platform connected by a welded joint to the side guards. A folding tailgate is provided for loading and unloading.
Transformer structures are trailers for universal use; they have the functions of both a rigid body trailer and a platform for transporting large cargo. The frame base is a rigid base, and folding or removable sides during transformation form an additional area of the flat platform.
The tipper type of walk-behind trailers allows for tipping and unloading of bulk cargo without additional effort.
How to make trailer brakes
Motoblock trailer brakes. The braking system facilitates and increases the safety of cargo transportation. There are many options for brakes, but as practice has shown, the most effective are motorcycle brakes.
How to make brakes on a trailer for a walk-behind tractor? Homemade trailer brakes are made from a cable, rod and drum. The drum must be attached to the rear wheel hub. The free spaces between the protrusions are filled with large wire. Next, a piece of pipe is welded to a pre-sharpened disk, which is installed on the axle. The brake pads are also attached to it, from which the cable will come to the lever. The brake is installed only on 1 wheel and this is quite enough to perform this function.
You can make any seat on a walk-behind tractor with your own hands. It can be short or oblong. It is made in the form of a box or chest, into which you can later put tools or improvised items. If the side of the cart is too low, then it is better to come up with a seat with a backrest so as not to strain the spine. To increase comfort, it is better to cover it with soft material.
If a chair or armchair is used as a seat, then 2 deep connectors are made for the legs for immersion inside. Thus, the chair becomes removable.
To attach a trailer to a walk-behind tractor, you need a hitch and a console. They can be removed from any decommissioned equipment.
A trailer device may have 1 axle, which has a weak center of gravity. It is important to install the body correctly so that there is no overstress at the coupling point. Therefore, the center of gravity must fall under the axle of the wheels. It is much more reliable with two-axle trailers. The weight distribution of the load falls not on 2, but on 4 wheels. They are suitable for transporting loads up to 1400 kg. You can use a car trailer.
Bicycle rack on the tow bar: choose from popular ones
Even if a person is going to make a trailer using step-by-step instructions, he still must understand the design features in advance. It consists of the following components:
- frame, which is the basis of the trolley;
- body used to load transported cargo;
- a coupling device with which the unit will be attached to the walk-behind tractor;
- seat;
- chassis.
First you need to make the frame of a walk-behind cart.
Why does the brake pedal fail after replacing the pads? What to do?
To design a high-quality trolley, you need to make a drawing of it in advance, on the basis of which the design will be created. To do this, you need to draw a rough sketch of the future cart on paper. In this case, you need to indicate the exact dimensions on it.
The trailer must be created based on a pre-drawn drawing
The drawing should be as detailed as possible. Therefore, it is necessary to mark all the elements of the trailer described above.

Frame
The very first thing that needs to be done is the frame. To make it, you will have to weld parts of a metal square pipe. Its dimensions must be at least 60x60 mm.
All joints must be welded with small seams. The joints must be checked with a square to ensure there are no bends. You can also use a building level for this.
After assembly, the frame must be primed and painted.
