The cutting blades and smoothing blades of a road maintenance vehicle are adjustable in position with respect to the wheels to avoid extremes in changes in the depth of a cut by a blade or the height of the blades caused by wheels of the vehicle dropping into low places in a road. By including a selected number of wheels mounted to the same stiff frame, the wheels riding on the highest part of the road will lift the rigid frame and other wheels rather than the wheels riding on the lowest part of the road determining the depth of the cut of the cutting blades. The height of the blades with respect to the wheels can then be adjusted so that they never cut too deep and overly stress the blades but do cut the highest elevations of the road and move the loose dirt and gravel into the lower parts of the road. A first frame is supported by wheels and a second frame is movably mounted to the first frame.
