ABSTRACT:
A vehicle has a housing mounting within it a rotor assembly comprising parallel shafts having intermeshing cutter discs in axially spaced relation thereon. The discs have radial projections with first cutting edges extending axially to face in a rotatively leading direction. Cutter segments carried on the discs project radially outwardly to provide second cutting edges of lesser axial extent facing in the leading direction. A toothed member mechanism carries teeth which project into the axial spaces between the discs and provides axial surfaces for coacting with the first and second cutting edge.
