Abstract
Teeth for compactors are normally utilized to crush and/or grind refuse material and/or soil being worked and to effectively compact the refuse material and/or soil being worked. It is also advantageous to insure that the teeth being used provide traction of the compactor wheel on the materials being worked while not allowing the refuse material and/or soil to collect between the teeth of the compactor wheel. In the subject arrangement, the tooth provides a tip portion having an outer surface with at least six edges and a plurality of corresponding side surfaces extending therefrom at an obtuse angle with respect to the outer surface. The tooth defines a longitudinal plane therethrough that is parallel to the length of the tooth and perpendicular to the outer surface. Two of the side surfaces lie perpendicular to the longitudinal plane and form obtuse angles with the outer surface in the range of 115 degrees to 135 degrees. The angle of the two side surfaces with respect to the outer surface and the angle of the plurality of other sides with respect to the outer surface provides a tooth that effectively penetrates the refuse material and/or soil being worked, crushes and/or compact…
