Abstract

An automatic dump bucket has a bail which can rest in an inclined position or a vertical position, the bail of the dump bucket pivotable about pivot pins that are not secured to the side wall of the bucket but which are disposed in a bore in a pivot pin support plate on the side wall of the bucket, in a pivot pin aperture in a side wall of an enclosure bracket and trapped by a pivot pin locking plate. The pivot pin and bail contact area can be lubricated by forcing a lubricant through an opening in the pivot pin locking plate and a passageway formed in the pivot pin. The dump bucket also has fork lift channels and roll-over blocking channels and, when dumped, assumes a position beyond a parallel position with the bail.
