All of the DR Chippers are designed to handle any wood that can fit down the hopper opening (within the maximum diameter ratings) and make rigid contact with the knife-edge.
Material that is extremely flexible, soft, lightweight, fibrous or sticky such as vines, leaves, weeds and prunings will not adequately chip or may even clog the discharge chute. For this type of material, you will want to consider a DR Chipper/Shredder which is desgined for chipping tree branches and shredding different type of debris.
