Abstract:
A rotatable grading pick has a head portion, a shank portion extending rearwardly from the head portion, and a polygonal portion on the rotatable grading pick. At least a portion of the outer perimeter of the polygonal portion can be engaged by a tool so that the polygonal portion can be rotated, and the shank portion can be rotated to clear debris between the shank portion and a retainer placed around a part of the shank portion.
