摘要：
FIELD: agriculture machine building.SUBSTANCE: invention relates to agricultural machine building, in particular to disc tillage tools. Set of post-and-housing reduction drives with replaceable rotating blades in full assembly is installed in the frame of agricultural machinery. In the primary main assembly the set comprises a circular flat disc having a hole in the center and fastening holes around it. Disc is mounted in a tubular equalizer and welded in inside from the both sides in a circle. In the equalizer, through the same spacing in a circle, six process holes are made, into which the blade axes are inserted with a neck clearance, on which a mounting flange is made at the lower end. In the flange, four or six working parts from the strip are installed and welded in by the upper edges in the grooves, with a transverse semi-rhombic cross-section with sharp edges. Working parts are bent L-shaped from the top to the bottom and have the same dimensions along the working outlines circumference and length. Outline two parts located opposite, are bent radially, and the lower ends are until contact and welded. On the flanges, eight-tooth disc mills of the same dimensions along the circumference and selected length can be bolted from the bottom. On each blade shaft a neck of a square cross-section is made, on which a gearbox small gear is installed, and the axes with bearings are seated in a body welded in to the disk in along the circumference opposite to the process holes. At the driving housing forward end a gearbox large gear is welded in, contacting by oblique teeth at the circumference edge with oblique teeth of the blades small gears, bringing them into the rotary motion at the time of their location on the lower gear segment in the large gear. At the exit from the soil, the blades small gears contact the of the large gear without teeth semicircle upper part and stop rotating together with the blades on its entire smooth surface until the moment of its teeth con
