Types of potato digger for walk-behind tractor
Previously, harvesting was carried out only by hand. Untreated virgin soil greatly complicated this process, so manufacturers began to develop types of potato diggers for soil cultivation, allowing them to dig out potatoes, huddle plants, and loosen the soil without any problems. A potato digger for a walk-behind tractor is an indispensable equipment in the processing of large areas of land.
Types of potato diggers for a 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 grabs the ground and transfers it to the shaking department. After this treatment, small stones are sifted out, most of the land is removed, and the potato tubers are left on the surface.
The working mechanisms still have some peculiarities. Types of existing potato diggers:
- vibrating potato digger (screen type);
- universal lancet digger;
- conveyor.
Vibration models
The screening type potato digger (KBN or boar, KKV-012) is considered more efficient than the universal model. People call it "shaking". With its help, up to 98% of potato tubers are removed from the soil, which significantly increases productivity. The structure includes a vibration part, plowshares and a drive.
During harvesting, the equipment picks up the top layer of soil along with the tubers and places them on a vibrating table. Under the action of the main mechanism, potatoes are cleared of soil residues. The fruit then exits through the ejection mechanism on the other side of the structure. The price for such models is high, so the easiest way is to use the advice of Yuri Serbin or Ildar Leskov and make it yourself.
An analogue of the vibration model is a drum structure designed for agricultural and cultivation work not only in open areas, but also in greenhouses. It is equipped with a special mesh and a hopper (drum).
Universal model
The universal model raises about 85% of the crop to the soil surface. It has a simple structure. The main advantage of such a unit is its low cost. The crankshaft is equipped with one or two eccentrics.
The equipment works without connecting the PTO shaft. To old models, the pointed universal potato digger is connected without using a PTO, in appearance it resembles a shovel. Another plus is the absence of complex parts in the mechanism, which simplifies maintenance.
A simple-type 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 walk-behind tractors. The price of the simplest model is about 1100 rubles. It is also possible to make it yourself.
Conveyor model
The equipment is similar to a vibration-type potato digger.Instead of a vibrating table, the conveyor variation is equipped with a belt system. During harvesting, potatoes pass through it, quickly clearing away soil residues.
The main advantage is the ability to adjust the distance between the working elements. The active suspension and keyed belt provide better ground traction. It is also used as a cultivator.
One of the disadvantages is the high cost of equipment, therefore, the conveyor model is more often used for processing land on an industrial scale.
It is used with tractors with a capacity of at least 25 l / s. Digging with a depth of 150 mm ensures the collection of the entire crop: MTZ, Khoper, Grasshopper, Bomet. Diesel fuel is used to improve performance. The conveyor is attached to a mechanical potato digger with an adjustable chain attachment.
The most popular potato diggers for motoblocks
The choice of device depends on the size of the site
A potato digger for a manual walk-behind tractor is selected in accordance with the following criteria:
- the weight;
- Efficiency;
- the quality of the material for the manufacture of wheels and frames, its environmental friendliness;
- functionality.
The dimensions of the design of manual potato diggers may differ, so the tool is chosen taking into account their capabilities and the scale of the land plot.
There are single-row and double-row models. A single-row potato digger for a walk-behind tractor performs only one action, processing 1 row, at the same time, a two-row digger processes 2 beds at once, and is also used as a hiller.
KKM1
The potato digger for the KKM1 walk-behind tractor is a small device designed for mechanized harvesting of potatoes, beets and onions.

The operation of the engine is also adjustable, which makes it possible to adjust the softness of the separation. Before the start of harvesting, in 2-3 days the site is cleared of weeds.
Mini potato digger is suitable for work on motoblocks Neva-2a, MTZ-40, Favorit, Salut, Cascade. The potato digger is suitable for processing light to medium-heavy soils, with a relative humidity of 26%. KKM1 will cope with any work on an area with a soil density of 0.2 kg / sq. km and weediness with stone blocks up to 9 t / ha.
The technical characteristics for planting potatoes using this model are as follows: the step between the rows should be 70 cm. To increase the traction force, a load of 50 kg is hung on the motoblock bar.
KM2
This is a single row potato digger that allows you to harvest without damaging the tubers. It is designed to work in small-scale areas, suitable for the Belarus motor cultivator.
The device is well thought out, which allows you to quickly separate the potatoes from the soil, without missing a single tuber. One of the advantages of working with this equipment is ease of operation and maintenance: spare parts needed for repairs are available in any shopping center.
The device works on all types of soil. The wheel attachment with a bracket is located at the base of the machine, which allows you to adjust the plowing depth.
Poltavchanka

The table with scoring knives is attached to a vibrating mechanism, which is a 6 mm strip. With proper use of the device, the crop is harvested in 2-3 hours without getting your hands dirty.
Thanks to the well-coordinated work of powerful lugs, the potatoes are easily thrown onto the table. Here, the earth wakes up to the floor, through the bars, and the tubers move towards the end of the table. Then the potatoes are dropped down. The only tubers that can remain in the ground are those in the mole's burrow.
KVMZ
The potato digger is attached to any equipment
KVMZ is a hinged device designed for harvesting / planting potatoes. Vibrating potato digger for the KVM 3 walk-behind tractor, analogue of VRMZ, also belongs to vibration devices.
