distances causing the feedwheel 14 to remain level if a lifting force is encountered at the opposite end the oil moves along hydraulic lines 138 and 140 in the opposite direction producing the same result the feedwheel 14 can be lifted with or without an incoming load by passing through the control valve 142 from the hydraulic pump 144 fluid exerting a force on the bottom of piston 132 producing a lifting action producing an equal lifting force at the bottom of piston 133 the fluid from the top of the piston 133 flows through the control valve 142 back to the hydraulic reservoir 146 similarly a downward pressure can also be put on the top of cylinder 137 to force the slide box down after the material is passed through the feedwheel 14 the material is contacted by whatever tool combination of swing hammers 50 chipper knives 106 and hog hammers 120 is mounted to the disc assembly 18 breaking or chipping the material into a mulch by simultaneously using all three tools or a combination of the three tools a very efficient waste processor is obtained assuming all three tools are mounted to the disc assembly 18 the swing hammers 50 contact the waste first further crushing and compacting the waste while drawing the waste closer to the disc assembly 18 the hog hammers 120 will contact the waste second and further crush and compact the waste the chipper knives will then chip the compacted material into even finer pieces it is beneficial that the swing hammers 50 and hog hammers 120 crush and compact the material because the knives 106 of the chipper knife holder 100.
