Kku-2a

: Rotary digging tools or ploughshares lift the tuber-bearing layers of soil.

: The final cleaned tubers are separated from plant residue and delivered for collection. Modern Research and Improvements

The is a specialized double-row trailed potato harvester primarily used for digging potato tubers, separating them from the soil, and cleaning them of impurities. Developed originally in the Soviet era, it remains a subject of modern agricultural engineering research to improve harvesting efficiency and soil separation quality. Core Technical Specifications Machine Type : Double-row trailed combine. Working Width : Approximately 2.1 meters. KKU-2A

: It is often used in ridge (European) technology layouts with 75 cm row spacing. Operational Process

: The harvester features a ploughshare, main elevator, second elevator, lifting drum, topper, and a clutch cutter. : Rotary digging tools or ploughshares lift the

: Testing the effectiveness of soil-separating elevators in varying field conditions, such as clay-heavy soils.

: The system is designed to weed out roughly 60–70% of incoming soil, managing loads up to 130 kg/s. Developed originally in the Soviet era, it remains

: New experimental setups are often built upon the KKU-2A base to test rotary digging tools that better disperse soil layers.
