A plow-type cutter loader developed for use in hard coal seams. It has four horizontal stepped precutting blades, which make a precut from 8 to 12 in (20.3 to 30.5 cm), to weaken the coal immediately in front of the machine. It can be single or double ended, and is hauled along the face by winches. The coal is loaded onto a panzer conveyor, which is advanced behind the machine by compressed air rams.
