The 600 Series was designed for backyard clean up, but don't be fooled by its size. They were not designed for just chipping up a few small branches now and then. Everything about these chippers is heavy duty, and built to last. Any leafy, woody material up to 3-1/2" in capacity introduced into the hopper will be processed with ease. Engine options are 8-16HP, Electric or Pull start, Honda or Briggs & Stratton.
