Homemade rake for a walk-behind tractor: what you need, the manufacturing process

Rake for walk-behind tractor help to rake, agitate and double swaths of cut grass. This is a convenient and effective device that facilitates the work of farmers during haymaking. If you make an effort, you will be able to create a good homemade rake with characteristics that are not inferior to the factory models. This will require a set of materials and welding skills.

What is needed to make a rake for a walk-behind tractor

To make a useful mechanical tool with your own hands, you will need to assemble a set of materials. Rakes for a walk-behind tractor are made from the following raw materials:

• grain seeder disc;
• steel strip 170 cm long, 4 cm wide, 1.5 cm thick (wheels);
• 2 metal plates 9 cm long, 3 cm wide, 2 mm thick (frame mounts);
• retaining ring;
• 2 squares 25 * 25 mm (stands for support);
• metal pipe with a cross section of 14 mm (axis);

• thick-walled pipe with a cross-section of 30 mm and a length of 140 cm (drawbar);
• metal wire 6–8 mm in diameter (working parts);
• set of springs.

To design the device correctly, it is necessary to prepare a drawing of the rake. On it you can see the main components of the unit design. The device consists of a drawbar (1), a lever (2), a rod (3), a strut (4), a rack (5), a hub (7), an axle (8), wheels (9), and the rake itself (6).

Do-it-yourself rake on a walk-behind tractor: manufacturing process

First, we make the wheels. We take the disc removed from the grain seeder, remove the bearing from it and put a metal rod inside. We wrap a metal strip around the disk and weld it to its end side using corners.

We will make the base of the future device. We pass the axial tube into the wheels of the device, leaving 2-3 cm from the outside. From the inside we attach the retaining ring, from the outside we drill a retaining hole. At a distance of 10–12 cm from each wheel, we attach two steel strips on which the frame will be installed. In the central part of the axle, we drill a hole for the installation of the drawbar.

We will construct a working mechanism. We attach oblique supports to the wheel axle. They should be parallel to each other. We grind the protruding parts with a grinder.

We attach a pipe with thickened walls to them - this is the drawbar of the structure. If you take a pipe that is not thick enough, it may not withstand the load created on the rake. We attach a loop to the end of the drawbar, forming a joint with the walk-behind tractor. We put locking rings on both sides of the pipe so that the rake acquires a stable position. We install a lever on them, which will allow raising and lowering the teeth.

We make teeth for the working part of the rake. We use 6 mm wire for this. We give them a C-shape. We fix them by drilling or welding.

Install additional elements - the seat on the drawbar and the spring on the lever. Lubricate moving parts with grease to reduce friction. If the teeth are too long for work, we shorten them.

We create a reinforcement for the rake to avoid breakage in the future. To do this, take a metal plate 15 * 15 cm and strengthen the weak nodes with it. First of all, it is necessary to fasten the racks by welding the support to the middle. You should also strengthen your cravings. Otherwise, a high fracture load will occur. After the end of the manufacturing process, you need to check how the working part rises and falls and what kind of force it creates.

Mechanical hay rakes allow you to cope with a significant amount of spring work. The made model is universal. It will fit all brands of walk-behind tractors. A horse rake was taken as a sample, which has been used by people in Russian villages for a long time.
