An excavating implement which includes a blade defining a top surface, an opposed bottom surface, a rear edge, a front edge, and opposed end surfaces. Primary cutting edges are spaced apart along the front edge, and secondary cutting edges positioned between the primary cutting edges. The secondary cutting edges are recessed relative to the primary cutting edges. The secondary and primary cutting edges intersect with the bottom surface. The blade 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 to intersect with the top surface.

1. In an earth excavating bucket having a bottom wall with a beveled surface leading to a leading edge and a substantially flat bottom surface adjacent the leading edge, an excavating implement, comprising:a blade defining a top surface configured for flush engagement with the bottom surface of the excavating bucket, a bottom surface, a rear edge, a front edge, and opposite ends; primary cutting edges defined by the blade and spaced apart along the front edge; secondary cutting edges defined by the blade and situated between the primary cutting edges; wherein the secondary cutting edges are recessed with respect to the primary cutting edges; wherein the blade 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 and intersect with the top surface; a blade-to-bucket mounting attachment configured to rigidly secure the blade to the excavating bucket with the primary and secondary cutting edges spaced forwardly of the leading edge and with the secondary beveled surfaces forming a substantially continuous surface with the beveled surface of the excavating bucket bottom wall; and the bottom surface being substantially planar and intersecting the primary and secondary cutting edges.
