Crary® Bear Cat® Chipper/Shredders use heat-treated chipping blades and shredding knives. The thirty-six serrated edge shredding knives utilize a staggered pattern on the rotor shafts to maximize processing performance. Some brush in wood management jobs require more diversity. The SC5627B offers users the ability to chip larger material, shred smaller material and still have precise control over chip size with its screenless discharge system.
