Abstract:

A digging tooth adapted to extend forward from a leading edge of a bucket or the like. The digging tooth has a forward end, with an edge extending thereacross, and a rear end. The digging tooth further includes wing structure preferably formed integral with the digging tooth and extending from a surface on the tooth so as to provide the bucket with enhanced ground penetration capability while concomitantly shielding ground engaging components disposed rearwardly of a rear end of the digging tooth against wear and, thus, potentially extending the useful wear life of such components.
