ABSTRACT:
A posthole digger has first and second spaced-apart, substantially upright, pivotably attached handles. First and second cooperating scoops extend from respective proximal ends of the handles. The scoops are moveable between a generally open position for penetrating the ground surface, and a generally closed position for excavating. A cleaning attachment includes a stationary hollow sleeve attached adjacent the proximal ends of the handles. An elongate slide rod is received within the sleeve and extends between the handles for sliding vertical movement relative to the handles. An inner scraper is attached to an end of the slide rod, and is positioned between the first and second scoops. A spring engages the slide rod and normally urges the inner scraper upwardly into a storage position adjacent a top end of the scoops. A foot extension is formed with the inner scraper and is depressed by the foot of a user against the force of the spring to move the inner scraper downwardly along the length of the scoops. An outer scraper is secured to the foot extension and resides in closely-spaced relation to an outside surface of the scoops. The outer scraper is movable in unison with the inner scraper to clean away accumulated earthen matter from inside and outside surfaces of the scoops in the open position.
