FIELD: agriculture mechanical engineering.SUBSTANCE: invention relates to agricultural engineering, in particular to tools with variable width of coverage, intended for basic and continuous tillage. Tillage tool contains a frame with a hinged joint between the main and additional beams, telescopic tie-rod and dampener, hydraulic cylinder and working parts having hinged on the main beam plowshares, breasts and posts. Connection between the main and additional beams is located at a distance of 0.53 of the main beam length, and the centers of the posts are located on the working body from the of the soil pressure midline to 0.12 of the plowshare length. On the posts there are protrusions, and on the main beam are ledges that limit the mobility of the posts in the hinges within 6…8°.EFFECT: such a constructive solution provides an increase in operational reliability and performance, taking into account of the particular field individual physical and technical features.1 cl, 5 dwg
