A trolley for a walk-behind tractor is an indispensable item for owners of both large land plots and modest gardens. Of course, it can be purchased at almost any specialized store, but you can try to make it yourself.
Do it yourself
This device will simplify the processing of a summer cottage, and will also help to transport various cargoes from hay and harvest to the remaining garbage. Its manufacture does not require expensive and complex materials, rather, most of them will be found in the home workshop. In this case, a homemade cart will be much more economical than a purchased one, because the latter will cost from 12 thousand rubles in the case of a new design and from 8 thousand when choosing a used one. The dimensions of the designed trailer depend on what kind of load it has to work with. For example, to transport 2.5 centners of the load, the cart must have a width equal to 1150 millimeters, a length of 1500 millimeters and a height reaching 280 millimeters.
When it is decided what parameters the planned cart corresponds to, it is worth making the drawings, and then calculating the amount of the required material, including the channel. Craftsmen recommend based on those details that are already at hand, and if necessary, buy something else. A rectangular or square cross-section pipe is easily replaced by a round one, which is available. All detected parts must be cleaned of corrosion spots and covered with a rust converter with a priming function. Consistent with the drawings, some of them will have to be adjusted, removing unnecessary elements. Then they will only have to fit and combine.
Of the tools that may come in handy at work, experts call a welding machine, a drill or a full-fledged drilling machine, a grinder with peeling and cutting discs, as well as a special device equipped with rivets.
Many professionals recommend in addition to stock up on oil paint for metal or a special tool with a polymer filler. In the second case, the painting will be more stable, and the body will not have to be painted again by the end of the season. Coating is carried out before assembling large parts of the trailer.
Designing a Simple Cart
The simplest trailer is capable of transporting from 450 to 500 kilograms of cargo and accommodate approximately 8 packed bags of potatoes. If you study the drawing, it becomes clear that the self-propelled cart will consist of such typical elements as a body, carrier, frame, wheels and others. The frame will be most optimally welded from cut tubes having a round or rectangular cross section, as well as iron corners. This will be done on a flat surface, and with the use of electric arc welding. During operation, it is necessary that the seam is uniform at all joints, which are then ground by a grinder. The resulting design will be able to be used in areas with bumps and small differences in height. The body with the frame is usually fixed when using pins.
In addition, the installation of springs is recommended to minimize the shaking that occurs when driving on potholes. A dump truck cannot function without the help of a wheel axle, which is a 1 meter long pin, the diameter of which does not exceed three centimeters. It is important to follow when choosing a rod so that its wheels do not go beyond the boundaries of the body as a result. It will be possible to assemble the parts by welding through the reference angles, as well as the bars of the frame with scarves with longitudinal hinges. By the way, since the main load will be at the point where the trailer is connected directly, as well as to the turning zone, they should be further strengthened.
The body of the dump truck trailer is made of either metal or wood - boards or plywood. In any case, the thickness of the material should be at least 20 millimeters, and it would be better to strengthen it with the help of steel corners. To connect the frame and the body, support will be required. By their way, durable bars of 50 by 50 mm in size can act in their quality. The center of gravity should not cross the straight line of the wheel pin, and the installation of stiffeners is required from below and from the sides.
In addition, it is important to consider what the cart will be used for. If bags of cargo will be transported in it, then folding sides are not necessary at all. Nevertheless, for unloading, it is worthwhile to provide an opening rear wall of the body or tipping mechanisms for turning the device over. Of course, all sides are allowed to be fixed. In addition, they must be smooth inside.
In order for the resulting trailer to attach to an existing walk-behind tractor, a special part called the console will be required. In this case, the connecting mechanism has to be removed in the cylindrical body of the longitudinal joint and secured with a special thrust ring. This will allow to create the independence of the cart wheels from the wheels of a walk-behind tractor or other agricultural machinery, and therefore, to simplify the process of driving a moving vehicle. The hitch is formed from any suitable metal fragment, the length of which is determined so that the transport device is conveniently controlled.
The wheels are usually assembled from improvised materials - tires of a motor carriage, combining with the central part taken from other spare parts. Both axes are sharpened under the diameter of the bearings taken from the stroller of the motorcycle hub. For the wheel axis, a steel circle is required, the diameter of which reaches at least three centimeters, which will then be combined with welding with a longitudinal hinge and angular supports.
The bottom of the cart itself is more convenient to construct from a metal plate, the thickness of which varies from 2 to 3 millimeters. An edged board is also suitable, which is more affordable, but less stable.
Among other things, a driver’s seat and leg support are created for the driver. The seat is either fixed to the hitch or mounted directly in the back.
The need for brakes
Undoubtedly, it is worth adding a home-made trailer with a brake system. Otherwise, any descent from the hill may end in tragedy. Cart brakes are usually removed from another vehicle, such as a regular car or walk-behind tractor. The parking mechanism is considered to be the most suitable: with its help, you can fix the trailer in a stationary state for a long time, stop it while driving or even leave it at an angle. You can use the brake if you press the lever or the pedal.
To provide the trailer with the above function, as an option, you will need a motorcycle brake drum and pads , as well as the spokes of the motorcycle wheel again. The immediate alteration will take place using a welding machine and pliers. Pre-used discs are freed from cables and rods and sharpened by a specialist. Following the drums are put on the hub and fixed at the back. The resulting empty space between the ribs will have to be filled by wrapping the ribs themselves with an ordinary metal wire.
At the next stage, the disks are arranged on the axis and are mounted with bushings. In addition, it is worth welding a small fragment of a metal part, for example, a corner, to the axis to prevent the disk from moving. The cables are mounted on drums and reach the place from where the driver can activate the brake, usually a lever or pedal.
