Abstract
A loader bucket comprises a support member having a cutting edge disposed forwardly thereon. An adapter, having an earthworking tip detachably mounted thereon, is detachably mounted on the cutting edge and defines a bearing surface contacting a forward edge thereof. A single bolt detachably mounts the adapter on the cutting edge and comprises an eccentric cam formed thereon to effect the above bearing contact upon rotation thereof. The head of the bolt has a plurality of circumferentially disposed teeth formed thereon which engage like-shaped notches formed in a counterbore, defined in the adapter, to prevent rotation of the bolt. A nut is threadably mounted on a lower end of the bolt to further secure the adapter in place on the cutting edge.
