FIELD: agriculture.

SUBSTANCE: connecting device comprises the bracket for coupling with a tractor and at least one beam pivotally connected to the bracket and projecting therefrom in the direction parallel to the tractor motion direction. The chassis with the working tool having a cutting angle relative to the ground, mounted thereon, is pivotally installed on the beam. The connecting device comprises the upper thrust, the lower thrust and the central thrust. The upper thrust and the lower thrust each are pivotally connected to the bracket and to the central thrust forming a deformable quadrangle in the projection to the vertical plane parallel to the motion direction. The central thrust is pivotally connected to the chassis.

EFFECT: increased working tool control during the movement.
