Abstract
Material reducing apparatus having a drive arrangement for a pair of shafts carrying double edge cutter discs, motor driven transmissions for each shaft having different speed characteristics for reducing motor speeds to double digit speeds, bearings mounted in pillow blocks so that the pillow blocks can be opened to allow removal of the bearings so the shafts carrying the double edge cutters can be repositioned to present the cutters selectively to reduce material with either edge of the double edge cutters. The drive arrangement is also duplicated at the opposite ends of the pair of shafts for selective connection to drive the shafts either by one of the drive arrangements or by the duplicate drive arrangement.
