ABSTRACT:
In a track-driven tractor, stationary cutter blades are fixed to a chassis of the tractor and cooperating rotating cutter blades are fixed to a sprocket hub of the tractor. The cutting blades are operable to cut refuse entrained between the sprocket and the chassis, which tends to wrap around the associated hub, so as to avoid the build-up of refuse on the hub which otherwise can lead to unnecessary wear of the sprocket, the hub, and an assembly forming a seal between the hub and the chassis, as well as unnecessary fuel consumption.
