ABSTRACT:
An asphalt pavement milling machine is disclosed which includes mechanism for precisely controlling the depth of cut made by a rotating milling head carried on a machine frame. The depth-of-cut control apparatus includes a shoe adapted to slide over the pavement, and fluid power cylinder means which urge the shoe toward and away from the head-carrying frame through a rocker arm and a vertical slide. A similar device can be mounted upon an opposite side of the machine frame. A fluid power system interconnects the operating cylinders to level the frame and provide smooth, stress-free operation.
