ABSTRACT:
The apparatus includes a rigid frame having two rectangular openings therein that are covered with sections of expanded metal grating material. The frame has front and rear angled or sloping cutting edges that can cause some of the soil being leveled to be pushed onto the upper side of the grating sections, a tilting of the apparatus increasing the amount. The elevated soil can be sifted downwardly through the grating openings if of small enough size or retained on the sections if oversized. Whatever chunks or clods of soil too large to be sifted can be dumped onto the ground and pulverized by a back and forth movement of the apparatus over the large material with the apparatus appropriately tilted. Rocks and debris can be transported to a disposal location. Replaceable wear strips are employed. However, the edges of the grating sections are welded to the frame at an elevation above the wear strips to reduce the amount of wear on the underside of the sections.
