FIELD: agricultural engineering, in particular, presowing soil tillage tools. SUBSTANCE: working tool has two disks stamped from steel rolled sheet provided with convex parts in mid portions. Disks are interconnected. Projections made on peripheral parts of disks are manufactured wedge-shaped, with wedge being oriented in radial direction, and provided with spurs positioned at an angle to disk surface and disk axial section. Projection is formed by cutting out and bending of spurs, with bending angle relative to disk plane being variable within the range of 15-90 deg. During advancement of working tool in one direction, grinding and mulching effect is enhanced, and during advancement in opposite direction compaction and covering effect are intensified. EFFECT: increased efficiency, simplified construction and wider operational capabilities. 6 dwg
