A multipurpose roller comprises a horizontal shaft, the ends of which are fixed in bearing units and on which working elements, made as immovable wheels with the smooth or toothed surface and movable clod-crushing wheels with the toothed surface are arranged. The immovable wheels by hubs thereof, the width of which exceeds the width of a rim, are pressed to each other, and the movable clod-crushing wheels, the internal diameter of which exceeds the outer diameter of the hubs of the immovable wheels, are freely arranged between them. It is additionally equipped with a means of cleaning the working elements, made as a false roller of the similar design (of alternating immovable and movable wheels) with the similar width of working elements, which is arranged in such a manner as to allow turning thereof at the end of the frame of the roller and which either rests on the roller, or rests on the soil for double treatment thereof. |
