Abstract: A pin assembly for releasably maintaining an adapter and replaceable part or tool of a two-part digging system in operable combination relative to each other. The pin assembly includes a pair of axially aligned retaining pins whose opposed ends are arranged in operable combination relative to each other. Each retaining pin has an enlarged head portion configured to fit within one of the openings defined by the tool, and a shank portion. An axially arranged and rotatable fastener maintains the opposed distal ends of the pins in releasably secured relation relative to each other. A method for releasably maintaining the digging tooth/tool and adapter is operable combination is also disclosed.

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 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.
