ABSTRACT:
The pavement planer of this invention is carried on the front ends of the twin lift arms of a skid-steer front end loader. It has a drum with radially projecting picks, confined to rotation in a box-like housing that is open at its bottom and is supported at its front center on a heightwise adjustable roller. Secured to the lift arms, spanning the distance between them, is an upright plate-like frame member that rides on a roller on each of its ends. The housing is so connected to the frame member as to be laterally adjustable relative to it and also tiltingly adjustable about a fore-and-aft extending axis. Both of those adjustments are effected by a single hydraulic cylinder jack connected between the housing and the upright frame member. In use, a down load on the lift arms imposes part of the weight of the carrying vehicle onto the pavement planer, to be supported by the three mentioned rollers.
