Abstract: A shredder for reducing used solid waste material to chips is described. The shredder and a storage container for the shredded wood are a part of a single mobile unit for on-site shredding and removal of shredded waste. A single drive engine is used to propel the vehicle in typical highway travel mode and also to power the shredder and auxiliary motors. A special vehicle drive unit/shredder coupling system is used to minimize torsional stress and strain on the drive engine. A lift mechanism is used to lift the pallets into the shredder and a paddle/pressurized air system is used to convey the shredded waste to an attached trailer.
