Abstract

An excavating implement (10) is described which includes a blade (20) defini ng a top surface, an opposed bottom surface, a rear edge, a front edge, and opposed end surfaces (30). Primary cutting edges (34) are spaced apart along the front edge, and secondary cutting edges (38) positioned between the primary cutting edges (34). The secondary cutting edges (38) are recessed relative to the primary cutting edges (34). The secondary and primary cuttin g edges (38 and 34) intersect with the bottom surface. The blade (20) also defines primary and secondary beveled surfaces forming acute angles with the bottom surface, and which extend angularly toward the rear edge from the respective primary and secondary cutting edges (34 and 38) to intersect with the top surface.
