Description Put your Category 1 tractor to work! Tear through hardwood branches up to 4.75" in diameter. Big hopper accepts side branches to minimize pruning. PTO shaft included. Extended discharge chute available. Features PTO Shaft Included: We provide a PTO shaft with the DR Chipper to simplify connecting and disconnecting. You can use it with any Category 1 tractor. Self Feeding Action: A large vertically oriented hopper, a precisely-angled heavy-duty chipping knife, and a powerful air channel work together to pull branches into the chipping hopper and blast wood chips out the discharge. Most materials will self-feed, so once you drop a branch in, you're free to get the next one. No force feeding required! Oversized Chipping Hopper: The big opening for branches (17" x 27") accepts 4.75" branches with little or no trimming of side branches. Pro-Spec Chipper knife: Made of high-carbon/high-chromium forged alloy tool steel, our knives hold an edge longer than those on "bargain" chippers. Still, as with any cutting tool, keeping a sharp edge is important for maintaining peak performance. We recommend keeping an extra on hand so you can minimize downtime.
