FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry, in particular to tools for compacting soil. The tool comprises rollers mounted on a frame in sequence, made in the form of hollow cylinders of equal diameter. On the side surface of the front cylinder the holes are made, arranged in a checkerboard pattern, the diameter of which does not exceed the size of soil lumps, maximum allowable of the agrotechnical requirements. On the roller axes on one side the sprockets of the same diameter are mounted, connected by chain. The roller axes are mounted with biasing from the horizontal axes of symmetry of the cylinders at the same distances. The axis of one roller is biased from the horizontal axis of symmetry of the cylinder in the direction opposite to the displacement of the axis of the other roller.

EFFECT: constructive implementation enables to improve the quality of soil compacting and soil lump crumbling.
