Justification of an effective method of potatoes harvesting

It is proved that high-quality potato harvesting is one of the most important technological operations that contributes to improving the safety of tubers during their storage. It is established that the digging working body on the potato harvester has low agrotechnical performance parameters, which directly affect the productivity, quality of harvested tubers, work and resistivity of the harvesting unit. A bar digging working body is proposed, the use of which allows to reduce the volume of soil supplied to elevators, which improves the separation of pile, and the tubers after the passage of the unit are not covered with soil coming off the conveyor. In addition, the rod working body allows the harvesting machine to work within the limits of agrotechnical requirements, eliminating damages and losses of tubers, improving the aggregate composition of the soil, as well as reducing its specific traction resistance and increasing productivity
