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

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

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

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

Recent studies focus on optimizing the KKU-2A's design to reduce tuber damage and increase output quality. Researchers have experimented with:
