Types of potato digger for walk-behind tractor

Previously, harvesting was carried out only by hand. Untreated virgin soil greatly complicated this process, therefore, manufacturers began to develop types of potato diggers for soil cultivation, which would make it possible to dig up potatoes, spud plants, and loosen the soil. Potato digger for walk-behind tractor is an indispensable equipment in the processing of large areas of land.

Types of potato diggers for walk-behind tractor

Types of potato diggers and their mechanism

The work of potato diggers is usually no different from each other. In the process of movement, the working mechanism captures the earth and transfers it to the shaking department. After this treatment, small stones are sifted out, most of the land is removed, and potato tubers are left on the surface.

Nevertheless, working mechanisms still have some features. Types of existing potato diggers:

  • vibrating potato digger (screen type);
  • universal lancet digger;
  • transporter.

Vibration models

A potato-type potato digger (KBN or boar, KKV-012) is considered more effective than a universal model. People call it “shake”. With its help, up to 98% of potato tubers are removed from the soil, which significantly increases productivity. The structure of the structure includes a vibration part, plowshares and a drive.

Equipment during harvesting picks up the top layer of soil together with tubers and places them on a vibrating table. Under the action of the main mechanism, potatoes are peeled of soil residues. The fruits then exit through a swinging mechanism on the other side of the structure. The price of such models is high, so the easiest way is to take the advice of Yuri Serbin or Ildar Leskov and make it yourself.

An analogue of the vibrational model is the drum structure, designed for carrying out agricultural and cultivation work not only in open areas, but also in greenhouses. It is equipped with a special net and a hopper (drum).

Universal model

The universal model raises about 85% of the crop to the surface of the soil. It has a simple device. The main advantage of this unit is its low cost. The crankshaft is equipped with one eccentric or two.

The equipment works without connecting the power take-off shaft. The lancet universal potato digger is connected to the old models without the use of a PTO, in appearance it resembles a shovel. Another plus is the lack of complex parts in the mechanism, which simplifies maintenance.

A simple fan-shaped digger is a mechanism similar to a rake. It also belongs to the simplest designs, for example, VIL, it is used for various types of potato diggers for motoblocks. The price of the simplest model is about 1100 rubles. Also, it is realistic to make it yourself.

Conveyor model

The equipment is similar to a vibrating type potato digger. Instead of a vibrating table, the conveyor variation is equipped with a belt system. During the harvest, the potato travels through it, quickly cleansing from the remnants of the soil.

The main advantage is the ability to adjust the distance between the working elements. Active suspension and a key belt provide better traction on the ground. It is also used as a cultivator.

One of the drawbacks is the high cost of equipment, so the conveyor model is often used for processing farmland.

It is used with motor tractors with a capacity of at least 25 l / s. Digging with a depth of 150 mm provides the collection of the entire crop: MTZ, Khoper, Grasshopper, Bomet. To improve performance, use diesel to refuel. The conveyor is mounted on a mechanical potato digger with an adjustable chain device.

The most popular potato diggers for walk-behind tractors

The choice of device depends on the size of the site

A potato digger on a manual walk-behind tractor is selected in accordance with the following criteria:
