FIELD: agriculture.
SUBSTANCE: invention relates to agricultural vehicles. The adjuster of hook load of swing type comprises a hydraulic cylinder, torque arms, swing blocks, torsion bars, hinges, brackets and levers. The blocks are mounted on the hinges at the lower part of the hubs of rear drive axle of the tractor and consist of a central guide and torsion bars. The ends of the torsion bars are combined with the torque arms with the splined inserts. One arm passes through the coupling device of the aggregated tool, and the other is a part of the fixing unit of the pressing damper. The fixing unit is mounted on the tractor frame by a hinge and consists of a power hydraulic cylinder and a pressure arm with a damper.
EFFECT: ability to distribute the adhesive weight from the hook device to the additional drive axle of the wheel tractor is achieved.
