FIELD: agriculture.

SUBSTANCE: invention relates to devices for contour trimming bushes and can be used in forestry, agricultural and community facilities. The device comprises a housing with a knife-divider and a shaft mounted in it to transmit torque to flywheel closed with the protective casing. The holders are fixed through the axes on the flywheel. In the slots of the holders the movable knives are inserted, pressed from the bottom by conical bushings. The bushings rest on the knives by the collars by means of bolts and washers, pressed by the upper clamps. On the upper planes of the peripheral parts of the holders the torsion springs are mounted coaxially to the upper clamps. The torsion springs are made in the form of an open ring and have rectilinear peripherally projecting free end. The holders are connected by the tension spring, and are limited in rotation around the axes by the stops with buffers mounted in them.

EFFECT: constructive implementation enables to improve reliability of technological process and to reduce energy.
