The SpeedScreen bucket separates rocks during a normal excavator digging operation by screening the material with a special-shaped, non-hydraulic moving screen. As material is scooped, the screened material goes into the bucket and rocks are forced up the ramped screen. When the bucket is partially dumped, rocks roll off the screen first into a pile, truck or side of the trench for later use. The specially designed screen is hinged so that every other finger opens to allow ease of dumping of the screened material. The self-cleaning design prevents rocks, roots and other debris from getting stuck between the bars.
