I have a 730 that I bought new almost 2 years ago. Mine has the 84 hp kubota but you can buy one with a higher hp John Deere motor. The chipper tows easily and has plenty of power for 8" softwood and maybe 6" hardwood like oak. I don't tend to chip bigger hardwood since we sell firewood. I can't complain since my first chipper was a Mitts and Merrill and this has been a big step up. I once read that it clogs easily on deadwood but this has not been my experience. Just keep the knives sharp and the anvil adjusted.
