The principle of operation of a potato digger is simple: it raises tubers to the surface, they must be collected from the garden by hand. However, it is worth paying attention to how the equipment is attached and how it behaves in operation.

KKM-1

Installation with a pulley takes 5-7 minutes. It is fastened with three bolts and provides a fairly rigid hitch to the equipment. The belt will need to be replaced over time, but it is inexpensive. Before starting work, it is important to check if the bushings on the instrument are lubricated. The grease must be renewed if necessary.

The potato digger KKM-1 of "Neva" company can be adjusted according to the immersion depth of the knife and the angle of inclination of the screening grate. In total, the active elements of the product have three positions, changing which, you can adapt the operation of the unit to the conditions of a particular site. For heavy motoblocks, this digger can be equipped with a step for the feet, so that during operation, stand on the unit, and not follow it.

It is most simply attached to cultivators with a left-hand pulley. The vibration potato digger is very practical, although it looks unprepossessing. It has convenient dimensions, which facilitates transportation to the land plot. Features worth noting:

  • non-standard knife shape, capable of cutting even heavy soils;
  • the frame of the shaker is equipped with reinforcements in the places experiencing the most severe load;
  • the shaker moves along a lifting-pushing path, thanks to which the tubers are well cleaned.

Important! If the walk-behind tractor is diesel, the unit may be connected to the power take-off shaft only after reducing the number of revolutions. For this, a special belt roller system is used.

"Neva"

The original vibrating potato digger for the Neva walk-behind tractor is attached to the cultivator with a pulley and a tension roller. The immersion depth of the trimming knife is adjusted by the height of the wheels. When working with heavy soils, the soil separation speed can be reduced so that the potato digger can handle the load and follow the track evenly.

KVM-3

This appliance is only suitable for cultivators with a power of at least 6 HP. Its active section is slightly wider and lower than most other models, due to which it runs more evenly on heavy soils. The advantage of KVM-3 is its relatively low price - from 8,000 rubles in Moscow. However, during operation, the installation requires some effort.

On a note. Hitching with a walk-behind tractor is simple, but difficulties arise with adjusting the digging depth and the angle of inclination of the active knife. When buying, you need to carefully examine the bushings, which may be defective (according to customer reviews).

During operation, the vibration of the entire structure is quite strong, so it is difficult to work with it for a long time. In addition, it is enhanced by installing an additional knife. However, KVM-3 can handle difficult soils, even with weeds and poorly harvested tops.
