: As the soil and tubers move through the bar elevators, soil impurities are shaken off through a process intensified by a specialized shaker.

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

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

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

: The harvester features a ploughshare, main elevator, second elevator, lifting drum, topper, and a clutch cutter.

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

: The system is designed to weed out roughly 60–70% of incoming soil, managing loads up to 130 kg/s.

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