Digging plowshares accomplish initial operation in technological process of potato harvesting and directly influence the following operations of harvesting equipment. While using rotation soil separator, adequate choice of the form and parameters of the plowshare appears a serious problem of effective harvesting of potato. One of the main parameters of the plowshare appears the horizon inclination angle, determining minimal resistance to furrow slice movement and minimal probability of soil mass lifting. The method of calculation of key parameters of the passive digging working organ (plowshare) of potato harvesting machine is given in the article taking into account that right after a plowshare the active working organ for destruction of dug-out soil layer and partial separation of the soil is being established. Structural parameters of this working body for a two-row machine, effort of a prop of a soil layer, traction resistance and efficiency are defined.
