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 the wheel 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 wheel assembly of the subject invention provides teeth that are positioned across the width of the wheel assembly in a plurality of rows. The outermost row is positioned adjacent the outer periphery of the wheel assembly while the innermost row is spaced from the inner periphery a preselected distance (X).
