Abstract
A loader bucket comprises a bottom wall having an elongated general purpose edge disposed forwardly thereon. A reversible cutting edge is bolted onto an underside of the general purpose edge, along with a plurality of laterally spaced adapters each having a hardened earthworking tip detachably mounted thereon. In a first embodiment of this invention, a plurality of laterally spaced bores are formed to a limited depth on the upper side of the cutting edge and the lower end of a bolt stud is welded within each bore. The stud extends upwardly through aligned holes formed through the cutting edge and the adapter to have a nut threaded on the upper end thereof. In a second embodiment of this invention, a continuous slot is formed along the cutting edge to receive the studs therein. Alternatively, the bores or slot may be formed on an underside of the general purpose edge. In carrying forth the method steps of this invention, the studs are flash welded to the upper side of the cutting edge prior to assembly thereof on the bucket.
