Abstract
A backhoe is provided with a retractable scraper and scarifier. The backhoe excavator bucket includes a stationary first mounting plate and a second plate pivotally mounted thereon for rotational movement with respect thereto and which carries a scarifier assembly. The scarifier assembly is movable in a plane parallel to the second plate. The second plate is provided with a lower rearwardly curved cutting edge or scraper portion containing slots through which the scarifier teeth may be extended or retracted. Rotational movement of the second plate with respect to the first and movement of the scarifier assembly with respect to the second plate is accomplished by hydraulic or pneumatic cylinders controlled by the operator of the prime mover.
