ABSTRACT:
The excavator bucket attachment apparatus provides an improved attachment of an existing excavator bucket to the existing lift arm and hydraulic cylinder. The apparatus replaces a plurality of attachment components, including 4 attachment pins, with a more basic assembly that saves considerable parts cost and labor in maintenance of a bucket attachment. The apparatus further provides a method of conversion of an existing bucket attachment to the present apparatus.
