ABSTRACT:
A backhoe bucket especially adapted for use in rock strata such as caliche, limestone and soapstone and plastic soils includes a shovel-nose configuration having a plurality of spaced-apart teeth symmetrically arranged along upwardly and rearwardly inclined leading edges of the angled bucket sidewalls. The sidewalls of the bucket to which the teeth are attached intersect a flat, horizontal bottom having a width substantially equal to the width of the tooth mounted thereto. The teeth are arranged in a symmetrical stair-step configuration with each tooth being above and behind an adjacent tooth closer to the center of the bucket. The teeth first fracture, then separate and guide material into the bucket. The rear wall of the bucket is a complex, curved panel which defines an internal volume shaped to receive and readily discharge spoil.
