ABSTRACT:
An excavation bucket assembly for an excavation apparatus such as a front-end loader includes a plurality of shrouds and tooth assemblies mounted along a lip of the bucket body. The shrouds are connected via reusable connection pins that are biased within aligned connection-holes with a plunger assembly mounted within the connection pin. The connection-holes are defined by two overlapping ovals, with the proximal oval having a larger radius as compared to the distal oval. Additionally, an improved attachment pin is utilized to connect a tooth portion to a tooth body portion of the tooth assemblies that provides for a secure and reliable attachment and easy exchange of worn tooth portions.
