ABSTRACT:
In the operation of a landfill compactor, it is a common problem for the wheels to pick up debris, especially wire and cable, and carry it around with the wheels as they rotate. When the debris falls from the wheels in the direction toward the frame and the axles, it becomes packed between the frame and the axle hampering machine operation and requiring hours of corrective maintenance. The apparatus of the subject invention for inhibiting the wrapping of debris about the axle assembly provides a hook member to ensnare debris. As the wheel rotates, the debris picked up by the hook member is dragged across a serrated blade portion mounted on the axle assembly to pull apart the debris and thus prevent the debris from wrapping around the axle assembly.
