A third pair of blades for enhancing the shredding characteristic of the cutter are mounted to the opposite ends of a second blade holder having a longitudinal axis disposed perpendicular to a longitudinal axis of the first blade holder. The third pair of blades are located to operate at a height in between the respective heights of operation of the first and second blades and are located to trace a path which is radially inward from thattraced by the first and second blades. The second blade holder is mounted to thefirst blade holder exclusive of the drive shaft to which the first blade holder is coupled and may be removed or assembled without disturbing the mounting of the first blade holder.
