: Rotary digging tools or ploughshares lift the tuber-bearing layers of soil.
: New experimental setups are often built upon the KKU-2A base to test rotary digging tools that better disperse soil layers.
Recent studies focus on optimizing the KKU-2A's design to reduce tuber damage and increase output quality. Researchers have experimented with:
: It is often used in ridge (European) technology layouts with 75 cm row spacing. Operational Process
: As the soil and tubers move through the bar elevators, soil impurities are shaken off through a process intensified by a specialized shaker.
: 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.
