FIELD: agriculture.

SUBSTANCE: invention relates to agriculture machine building, namely to attachments secured on the tractor, in particular to forest machines and tools. The attached system comprises bottom tie-rods (1), top tie-rod (3), drive levers (5), shaft (4) and hydraulic drive. The bottom tie-rods (1) are connected by braces (8) with the lifting levers (7). To free ends of the bottom (1) and top (3) tie-rods a triangular truss (9) is hingedly connected. On opposite side of the tie-rods (1 and 3) on the triangular truss (9) bottom (10) and spring loaded relatively to the truss top (11) levers are hingedly secured. To free ends of the levers (10 and 11) the attached tool (12) made in form of the disc work tool (13) is connected. Projections of the bottom (10) and top (11) levers on the longitudinal-vertical plane upon their movement upwards create converging lines, point ("МЦВ"₁) of their crossing is located below the ground surface. Turns of the bottom (10) levers in the vertical plane are limited using the stops (15) with grooves hingedly installed on the truss (9).

EFFECT: design solution increases penetration ability and stability of movement at the specified depth.
