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.
: New experimental setups are often built upon the KKU-2A base to test rotary digging tools that better disperse soil layers.
: The final cleaned tubers are separated from plant residue and delivered for collection. Modern Research and Improvements KKU-2A
: Testing the effectiveness of soil-separating elevators in varying field conditions, such as clay-heavy soils.
: As the soil and tubers move through the bar elevators, soil impurities are shaken off through a process intensified by a specialized shaker. The is a specialized double-row trailed potato harvester
: The harvester features a ploughshare, main elevator, second elevator, lifting drum, topper, and a clutch cutter.
: It is often used in ridge (European) technology layouts with 75 cm row spacing. Operational Process Working Width : Approximately 2
: Rotary digging tools or ploughshares lift the tuber-bearing layers of soil.
