摘要

FIELD: agricultural engineering, in particular, equipment used for improving ecological conditions in grain sowing regions.;SUBSTANCE: working tool has hollow tine with sides and actuating members made in the form of rippers-slitters, parts arranged under hoe and equipped with holder, and horizontal shares, inclined shares with chisel, A-shaped hoe with three-faced many-sided wedges-mole plows, slitter with part under hoe and chisel, drum with wide and narrow blades. Different kinds of actuating members allow various combinations to be used for performing different kinds of soil tillage. Working tool allows stepped tillage, tiered tillage, chiseling, flat tillage and flat tillage combined with slitting tillage to be provided, as well as alternating wide and narrow holes to be formed on soil surface.;EFFECT: increased wind and water resistance of surface of plowed layer, provision for leaving stubble remains on soil surface.;5 dwg
