Potato peeling machines do not provide the necessary technological quality of the tuber cleaning process. The shovel separation system operating in heavy ground conditions must be equipped with a dynamic shredder of tubers. The driving mechanism of grinding and pipelining, operating on a dynamic principle, is located in front of the goiter of the potato peeling machine and covers the entire profile of the tuber. The ground chips cut from the tuber should be thrown into the aisle to reduce the amount of soil in the tuber-soil mass, the most purified tuber mass from the soil should be fed into the filter elevator. The analysis of the calculated value of the angle of installation of the knife shows that the optimal position of the knife in the range of rotation angles of the rotor depends only on the kinematic parameter. When justifying the parameters of a large-sized conveyor, determining the optimal value of the angle of installation of the knife is necessary, but still insufficient condition. A sufficient condition requires justification of the second parameter of the knife installation to ensure the simultaneous fulfillment of two conditions: cutting chips with an inclined slide and its ejection into the interline space. The installation condition of the knife is provided by sliding cutting, taking into account that it is necessary that the Earth chips be dumped into the aisle after cutting from the tuberous soil, to reduce the amount of soil in the tuberous-soil mass, a more purified tuberous mass from the soil is fed into the filter elevator.
