Motor grader blade-shifting hydraulic actuator and mount therefor

A motor grader includes a circle frame on which a blade is linearly shiftably mounted. For selectively shifting the blade, there is provided a reciprocable hydraulic motor of the double-rod-end-type. The cylinder of the hydraulic motor is fixed to the drawbar frame and the opposite piston rod ends are attached to the rear side of the blade, the attachment being made by respectively disposing a pair of pins, which are integral with the blade, in openings which are in the opposite piston rod ends and elongated in the direction of shifting. The pins are disposed in the elongate openings such that the piston rod means is in tension during actuation of the hydraulic motor.
