  • Patent number: 5553409
    Abstract: A wear protector system for shielding the leading edge of an earthmoving implement such as a loading bucket includes an arrangement of shrouds which cover the leading edge between the laterally spaced digger teeth. Each shroud has a nose portion that wraps around the leading edge and a rearwardly extending tail portion having an abutment surface that engages an undercut abutment surface of an anchor block that is welded to the bucket. The complementary abutment surfaces retain the tail portion from moving upwardly away from the bucket surface, whereas the shroud is retained from movement forwardly out of engagement with the lip by use of a cotter pin extending transversely through a passage that is formed partially in the tail of the shroud and partially in the anchor.
