A potato digging machine comprises a control grip, a frame with a driving engine arranged thereon and a reducer connected therewith having an output shaft arranged horizontally with running wheels arranged thereon and also a passive undermining device and a separating device. The running wheels are made as hubs with flat disks fixed thereon having a shape approximated to roundness and arranged relatively to the axis of the hubs in planes of axes of abscisses and ordinates for angles distinguishing from the rectangular one. The axle of a protecting wheel of a round shape looking as a truncated cone is inserted into the free end of the hubs. |
