Discs are divided into spiral sectors with two surfaces. The first surface has sharpening and smaller ascending angle than the second one. The poles are rigidly fixed on the frame and inclined to the line of motion to provide for penetration of the discs into soil. Poles are made as pipes with loading cone in the upper part and inserted screws. Discs are fixed on the poles by hinges and fitted with cone distributors. The distributors are connected to the discs by draw bars. Screws are coaxially welded to the cone distributors tops. Operation elements are placed on the frame in a staggered order.
