The machine is connected to the tractor with a three-point hitch system. The cardan shaft (shaft) is connected to the tractor PTO shaft. The tractor and the potato shredder, which is connected to the tractor with a 3-point hitch system, is positioned so that the wheels of the tractor enter the potato furrows, and the ground height of the mulcher is adjusted both with the tractor hydraulic arms and the roller or wheel height adjustment behind the machine. At the first start, the PTO shaft of the tractor is moved slowly. For this, the operator must slowly lift his foot off the tractor clutch. Otherwise, the shaft may break. When the blades of the machine reach a sufficient rotation speed, the tractor moves through the furrows and the potato grass is shreddered and distributed homogeneously on the field surface.
