ABSTRACT:
A housing having a V-shaped cross-section is adapted to be positioned over the teeth of a backhoe bucket. An earth moving blade is secured to the lowermost portion of the housing. Lugs are secured to the inside surfaces of adjoining teeth of the backhoe bucket. A retaining bar is inserted through apertures formed in the front and back faces of the housing to engage the lugs between the teeth and thereby retain the receptacle on the tooth portion of the backhoe to permit earth moving and grading operations.
