Abstract: An articulating grader comprises a rear driver section which has an engine and hydraulic pump arrangement for driving a pair of wheels on each side. A chassis frame includes lower frame members for supporting a mold board assembly which is controlled and set in angularity and vertical movement but supported from a frame support member on the top by a hydraulic piston and cylinder and guide member arrangement, whereby after adjustment the mold board may be moved upwardly vertically and again moved back down to original position without disturbing the setting. A front articulating frame supports steerable wheels controlled by hydraulic power steering.
