A planer assembly is mounted upon a main frame. The planer assembly has a set of blades installed upon a rotable drum. The blades have tips containing deposits of material which abrades hardened pavement. The planer assembly is mounted upon the main frame in a manner that allows the weight of the frame and other components to bear down upon the blade assembly. As the drum rotates, the blades grind paving material from the paved surface. The depth of grinding, or planing, is controlled by the distance between the blade assembly and the surface to be planed. The distance between the blade assembly and the surface to be planed is determined by the distance that is maintained between the frame and the surface to be planed. The distance between the frame and the surface to be planed is adjusted by turning a stationary threaded rod which engages a threaded block mounted upon the axle frame of wheels of the main frame. The axle frame is pivotally mounted to the main frame. Turning of the threaded rod moves the threaded block along the length of the rod causing the axle frame to change its angular relationship with respect to the frame.
