ABSTRACT:
A scraping blade adapted for quick, simple and easy attachment to and removal from a bucket of the type used with a backhoe or like earth working machine, wherein the lower cutting edge of the bucket has a plurality of outwardly projecting teeth terminating in tapered cutting/tearing points. The blade includes front and back plates providing a straight lower scraping edge and a substantially "V" shaped upwardly open receptacle or socket sized and configured to receive and snugly engage the projecting points of the bucket teeth. The front plate includes forwardly angled end sections adapted to prevent the spill over of dirt from the blade as it is being used to scrape and/or level dirt. The blade is releasably yet securely held in position on the bucket by a binder device consisting of a tether attached to the blade generally intermediate its ends, a hook attachable to a fixed support carried by the bucket, and a binder device releasably coupled to the tether and hook, the binder device being manually operable to pull the tether toward the fixed support to seat and maintain the teeth points in the blade socket under tension sufficient to prevent undesired shifting or movement of the blade relative to the bucket or its teeth as the blade is being used to scrape or level dirt.
