Abstract
A quick-convert bucket attachment for front end loaders has hydraulically positioned, interlocking bucket components that may be manipulated by controls at the tractor seat or other convenient location for rapid conversion of the attachment from a general purpose loading bucket to a side-shift angle dozer. The back wall of the bucket is formed by the dozer blade, while the side walls and floor of the bucket are formed by a clam which may be raised into an elevated position to expose the dozer, at which time the dozer may be either maintained in a centered, straight-forward position or shifted laterally into a left or right, obliquely angled position. The dozer blade is completely immobilized and is held solidly against a main base of the attachment when the clam is in its lowered position, thus presenting a rugged bucket capable of functioning in all respects as a conventional loader bucket at that time.
