Vibrating potato digger for a walk-behind tractor, Poltava region.

Vibrating potato digger with 2 eccentrics "Zyrka 61", intended for use with heavy walk-behind tractors with a power of 8 hp, equipped with a belt drive and a side PTO shaft. It is necessary to work with a mechanical digger at low speeds and increased traction. The recommended speed of movement on heavy soil is ≥2 km/h, on light soil ≥1 km/h.

The overall dimensions of the vibratingpotato diggers are 760x650x730 mm. The maximum possible depth is 20 cm. This is enough to dig up potatoes planted manually or mechanically. It is possible to operate a vibrating potato digger on various soils. Heavy soils should be loose and well worked. By the time of harvest, the land should be dry, and the plot cleared of weeds.

The vibrating potato digger KK8 consists of a frame, an active knife (plow), a sieve, two connecting rods, two eccentrics, a tension roller, a drive pulley,wheels and a clutch assembly. The work of the digger begins withstarting the walk-behind tractor through a belt transmission that drives connecting rods with eccentrics. Different eccentrics are responsible for the grater and the knife, so they move simultaneously in a reciprocating order. This ensures smooth operation of the digger and high-quality potato digging.

The principle of operation of the 2-eccentric vibratory potato digger: the knife cuts the layer of soil with potatoes, brings it to the top and drops it on the screen. The sieve shakes the tubers off the ground and throws them onto the row.

The KK8 vibrating potato digger allows you to harvest more than 90% of the potato and other root crops (garlic, onion, and some types of carrots) on an area of up to 2 hectares with minimal damage.
