FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of road engineering, in particular, to motor graders with hydraulic-powered control of the working body. The working equipment of the motor grader comprises a traction frame, a slewing ring of the working body with a gear crown, and two hydraulic cylinders with crank mechanisms and toothed gears. The crank mechanisms are connected with the toothed gears via mechanical controlled engagement couplings.
EFFECT: simple reliable system for controlling the slewing ring of the working body of the hydraulically driven motor grader, ensuring the protection of the elements of the main blade from breakage in case of collision with an insurmountable obstacle.
