Recent studies focus on optimizing the KKU-2A's design to reduce tuber damage and increase output quality. Researchers have experimented with:
: As the soil and tubers move through the bar elevators, soil impurities are shaken off through a process intensified by a specialized shaker. KKU-2A
: Testing the effectiveness of soil-separating elevators in varying field conditions, such as clay-heavy soils. Recent studies focus on optimizing the KKU-2A's design
: It is often used in ridge (European) technology layouts with 75 cm row spacing. Operational Process and a clutch cutter.
: The harvester features a ploughshare, main elevator, second elevator, lifting drum, topper, and a clutch cutter.
