An attachment for mounting to a front edge of a bucket, the front edge defining an inner surface, and outer surface and a beveled surface oriented at an inclination to the inner and outer surfaces, said attachment comprising a body including a base portion adapted to engage and mount to the front edge of a bucket and a working structure projecting forwardly from said base portion, said base portion defining a recess adapted to receive the front edge of the bucket, said recess being defined by at least an end face and a convex-shaped face, said end face facing in a generally rearward direction, said convex-shaped face being adjacent to and extending rearwardly beyond said end face and engaging the beveled surface of the bucket upon assembly, said recess being continuously open rearwardly and laterally to accommodate receipt of the front edge of the bucket.

An excavation bucket comprising:

• a rear wall, a bottom wall and a plurality of side walls, said walls cooperatively defining an open front and a cavity for receiving material therein, said bottom and side walls defining a front edge along the boundary of the open front, at least a portion of said front edge defining an inner surface, an outer surface and a beveled surface oriented at an inclination to the inner and outer surfaces;
• and
• at least one attachment comprising a unitary, single piece body having a rear base portion for engaging and mounting the attachment to the front edge of the bucket and a working end projecting forwardly from said base portion, said base portion including an end face facing in a generally rearward direction and at least one rearwardly extending leg having a generally convex-shaped face and engaging the beveled surface of the bucket upon assembly, said body further including a recess defined by at least said convex-shaped face and said end face, said recess being continuously open rearwardly and laterally to accommodate receipt of the front edge of the bucket.
