ABSTRACT:
Tractor mounted rotary cutting equipment of a type suitable for use in grinding down tree stumps to below surface level is provided. The cutting disc of the equipment is driven by an hydraulic motor through a flexible coupling and the hydraulic motor is, in turn, driven by an hydraulic power pack which is activated by the engine of the tractor. Preferably an over-run device is embodied to allow the cutting disc to continue rotating when the tractor engine is slowed down. The cutting disc preferably has cutters secured thereto by bolts or the like passing through a part of the disc and into co-operating screw threaded holes in the cutters.
