FIELD: agricultural engineering. SUBSTANCE: tillage tool has frame, main slitter and set of additional slitters. Tines of main and additional slitters are mounted on frame through pivotal bushing so that the whole set of slitters may be moved to operating and transport position. Bushing is provided with pivots arranged in pairs and oriented in radial directions. Rotary bushing is fixed on frame through stop and wedge. Stop is made in the form of rectangular prism and is inserted with its faces into slots formed in rear part of rotary bushing. Stop is engaged with walls of pair of diametrically opposite openings of hollow shaft. Wedge is positioned in horizontally oriented openings in hollow shaft of frame. Stop and wedge do not intersect with one another, but are mutually joined with their faces. Hollow shaft is aligned with horizontal beam of frame through junction plate and pin, which is inserted in openings formed in frame beam and in hollow shaft. EFFECT: wider operational capabilities and simplified construction. 2 cl, 6 dwg
