Abstract
An improved boom-supportable device for lifting large rocks, broken concrete or asphalt pieces, and the like from the ground without particulates. The invention includes a generally upright frame member having a lower edge, a shelf-like member extending laterally from the frame lower edge to a distal end and defining substantial voids, and devices removably attaching the shelf-like member to the frame lower edge selectively in either a forward position or a rearward position. The shelf-like member preferably has a plurality of elongated parallel teeth spaced along the lower edge. The teeth are most preferably separate, each individually attached to the lower edge.
