The most labor-intensive and energy-intensive part of the technology of machine production of potatoes is the harvesting process, which is mainly carried out by combines. Modern potato harvesters provide the required performance indicators in favorable operating conditions. In unfavorable conditions (which, in the first place, are characterized by high or low soil moisture), the completeness of the separation of tubers from impurities decreases, and the losses and damage to products increase. This situation is related to the imperfection of the separating working organs of potato harvesters. In the process of machine harvesting, up to 1000 tons of soil per hectare are screened on the separating working organs. As a result, the productivity of potato harvesters is generally determined by the throughput of their separators. Taking into account the fact that each technological element of the combine harvester consumes a certain power in the process of operation, it is possible to talk about forming a balance of the combine's power and the possibility of determining the latter's composite.
