ABSTRACT A tractor three-point linkage has a hydraulic single- acting actuator for raising lower linkage arms through a linkage including respective vertical tie rods. A flexible compensating bar is rotatably supported by two fixed brackets on the tractor, the central region of the bar cooperating with a cam surface on a pivoted intermediate member acting through a mechanical transmission on the displaceable valve member of a distributor which controls the operation of the actuator to lift the linkage arms when the ground reaction force on the implement exceeds a limit. To increase the speed of return of the implement to the ground the invention provides for return movement of the distributor valve in response to vertical flexure of the bar caused by the weight of the implement, when lifted out of the ground, acting on the bar through the arms.
