Abstract
An infeed hopper with a pivotable throat portion for feeding material into processing device. The pivotable throat portion has a first position in which it guides feed material from an inlet of the infeed hopper toward the processing device, and is movable from the first position so as to move the feed material through an outlet of the infeed hopper toward the processing device, particularly for forcing jammed material into the processing device. In another position, the pivotable throat portion provides access into the processing device for cleaning and maintaining the processing device.
