御装置。 A motor grader in which a blade is disposed on a frame of the motor grader so as to be able to rotate and move up and down by a circle drawbar, and a pair of left and right blade lift cylinders are pivotally connected between the frame and the circle drawbar, one of the blade lift cylinders. An angular displacement detection mechanism consisting of a relative angular displacement detection bracket and a limit switch is provided between the drawbar pivot joint and the circle drawbar, and the other hydraulic circuit of the blade lift cylinder is connected to the blade lift cylinder operated by the angular displacement detection mechanism. A blade control device for a motor grader, characterized in that it is provided with a driving solenoid valve that synchronizes and drives a cylinder.
