ABSTRACT:
A scarifying assembly mounted in a backhoe bucket is disclosed herein having a toothed roller operably carried between spaced-apart support arms which include bearings and a chain or geared drive coupled to a hydraulic power source. The attachments for assembling the opposite ends of the roller include splined fittings which revolve with the roller. Both the roller and splined fittings have outwardly projecting teeth angularly disposed with respect to each other and to the peripheral surface of the roller and the fittings. The roller attachments, fittings and hydraulic power source provide a readily convenient arrangement for rapid assembly or disassembly for service, maintenance and repair procedures. A wedge structure is carried on the power source having a terminating edge in close proximity to the projecting teeth for the purpose of breaking-up or fragmenting rocks carried between the teeth.
