The principle of operation of disc hillers for a walk-behind tractor
Modern technical equipment makes it possible to accelerate the pace of agricultural work and facilitate human labor when planting vegetables. Choppers and other hand tools are physically demanding and time consuming. A disc hiller for a walk-behind tractor is an indispensable assistant for a vegetable grower who grows potatoes and other crops in large areas and who wants to improve the planting process.
The principle of operation of disc hillers for a walk-behind tractor
Varieties of hillers
The hiller is intended for sprinkling wet soil to the plant stems and loosening it. The device serves as a weed cutter and in cutting and filling furrows for a tractor before planting potatoes. The quality and quantity of the future harvest depends on the literacy of the hilling work.
The farm uses several types of devices: with a fixed and selective working width, propeller type and disc hiller. Which one is better depends on what it is for. The former do not allow adjusting the width of the furrow, having set 25-30 cm. They are suitable for joint use with small and not too powerful cultivators. Due to their fragile structure, such models are not suitable for working with hard and damp ground.
Adjustable units are loved by potato growers, are suitable for large fields, and have high energy consumption.
The type of disc hiller for a walk-behind tractor is common among potato seeders, is suitable for large fields, and has a high energy consumption. There are multi-disc.
Propeller devices are capable of cutting the soil with their paws, spilling the furrows of the plant and weeding the weeds of the potatoes. They are comfortable to use, but are only suitable for devices with a double gear and without discs.
About the device
The disc hiller mechanism for a walk-behind tractor consists of a leash, a pair of racks, discs and tensioning devices. The latter regulate the angle of attack of the parallel inclination of the discs. Comfortable use of the device is ensured by the correct installation of these discs: the distance between their lower circles should be equal to the distance between the rows. The desired diameter of the hiller itself is 340-390 cm, its wheels are 75 cm, width is up to 10 cm. Observing these parameters, it is possible to protect plants from mechanical damage.
The appearance of a disc hiller for a walk-behind tractor is a two-wheel frame with a pair of discs suspended by a chain. Among its functions are pre-sowing and post-harvest cultivation of soil, inter-row cultivation and use as a cultivator.
Terms of use
The equipment will allow you to enjoy your work
In operation, the disc hiller for the walk-behind tractor is simple. It is important to set it up correctly before hilling. The distance between the lower and upper corners is doubled by moving the racks and bolts from the discs into the recesses of the leash. To maintain the balance of the unit, turn the single-row clamp through the same pivot angle.
- Setting the width between the discs. To make it easier to turn the clamps, a large washer is placed between their ears and the leash bar.A bolt is threaded through it, and over the angle of attack is tightened with another washer. The second is lowered by half a turn and covered with the third.
- Fastening the clamp and bar to the disc hiller. The device is connected to the walk-behind tractor through the hitch fastener without a longitudinal bar. The leash is held in place thanks to a stopper and flat bolts on which the pipe of the fastener is worn, while the bolts press the leash against the outer pipe. So the bracket is rotated along the longitudinal line to the required level.
- Attaching a disc hiller to a walk-behind tractor. The optimum working gear is driven at a reduced speed. The thrust increases. To prevent the wheels from slipping, they are pre-paired.
The work of an automatic disc hiller is based on the principle of soil capture by discs during their movement and the formation of a roller in the process of hilling and sprinkling vegetables with soil. The advantage is compactness, comfortable operation, less energy consumption when hilling potatoes, even processing of ridges. The price of the device varies, depending on the dimensions of the discs, material, adjusting mechanism, equipment with either a cascade-shaped hole or rolling bearings.
Self-production
The agricultural market provides a wide selection of hillers, among which are models of a disc hiller for a walk-behind tractor LAN, Neva, Standard Tselina 010409, Bulat, MTZ, Patriot, Kaskad, Salyut, Sungarden. This useful device is expensive (this also applies to the widespread Neva), so not every owner can afford it. Having minimal skills in assembling mechanisms and armed with drawings, it is easy to make a hiller yourself.
To assemble a homemade product, you will need 4 main components: a disc (2 pcs.), A double-row stand (2 pcs.), A screw tensioner (2 pcs.) And a T-shaped leash. As a material, you need a steel metal template with a thickness of 1.5-2 mm.
The role of the tensioners is to adjust the rotation of the discs. To facilitate the process, the installation of discs at a distance identical to the wheel track width and the width between the rows helps. To ensure balance and adjustment, the discs are set as symmetrically as possible:
- the hiller is attached to the walk-behind tractor using a sliding bracket;
- with adjustable bolts and a stopper, the hiller is connected to the edge of the bracket;
- the stopper is placed in a square tube, a clamp is made outside;
- the console is unrolled with bolts;
- with nuts, the leash is screwed along the longitudinal axis of the inclination.
Also, a disc hiller for a walk-behind tractor is made from covers from old pots or seeders. Their diameter should not exceed 60 cm.
The caps are sharpened around the circumference and bent with a hammer. One side should be convex, the other sunken, so that the disc touches the soil and sprinkles nearby bushes. The covers are connected to each other with adapters and welded with a stand, a leash and lanyards. Further actions are performed according to the above scheme.
Conclusion
A disc hiller for a walk-behind tractor is easy to make at home. A clear drawing of the device and a step-by-step following of the instructions help to design this simple device, indispensable in vegetable growing, and to optimize the hilling of potatoes.
