This study analyzes the field trials and technical-economic effectiveness of the KP-2 potato digging-loader harvester, which is equipped with a Centrifugal Lifting and Sieving Rod Elevator (CLSRE). The field trials were conducted in the Namangan region in 2024-2025. The results showed that the KP-2 harvester achieved superior performance compared to the traditional KPK-2 (complex harvester): labor input was reduced by more than 3 times (from 20 man-hours/ha to 3.3 man-hours/ha), and the total mass was decreased by 3.5 times (from 6000 kg to 2000 kg). The new technical solution significantly reduced tuber damage to below the permissible level (3.4%). The calculated annual economic benefit amounted to 25.041 million UZS (for 100 hectares).
