The mechanism incorporates a frame structure having a hydraulically driven slide supported and guided by parallel structural members of the frame. The cutter disk is rotatably supported on the slide structure and is driven by the power take-off of the tractor by means of an elongated non-circular drive shaft which is received in driving engagement by a central non-circular drive opening of the cutter. The cutter disk is movable along the length of the non-circular drive shaft while maintaining driving engagement therewith.
