CP47057BEN DR Wood Chipper



Our most powerful self-feeding chipper, this beast devours branches up to 5.75" in diameter. Electric-starting is standard. Available options include a road-towing kit and an extended discharge chute.

  • 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 your free to get the next one. No force feeding required!
  • Oversized Chipping Hopper: The big opening for branches (19" x 30.5") accepts 5.75" branches with little or no trimming of side branches.
  • Road Towing: Add the optional road tow package and you can easily tow your Chipper on roads at speeds up to 45mph. Please note: If you purchase the optional road tow package with your machine it will be factory installed and the standard pin hitch will not be included.
  • Commercial Grade Clutch: The commercial-grade centrifugal clutch on the 21.0 Chipper is similar to those used in well drilling. There is no load on the engine until it reaches 1,600 rpm. If you do manage to find a branch tough enough to slow the engine to 1,600 rpm, the clutch will automatically disengage the engine until it's back up to speed.
  • Briggs and Stratton OHV Engine: The legendary power, performance and durability of Briggs & Stratton® engines make them the only ones we use on our DR Chippers. The 21.0 FPT Self-Feeding Chipper uses a durable 420cc Overhead Valve engine with electric-start. It features a debris management system that protects the engine from whatever you kick up while you're chipping and shredding.
  • Heavy-Duty Flywheel: The key to efficient wood chipping is the rotating mass created by the flywheel on which the chipper knife is mounted. The 21.0 Self-Feeding model features a 20" diameter flywheel that's a 5/8" thick and weighs a hefty 62.5 pounds. It spins at 144 mph and takes an amazing 40 “bites" per second!
  • 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.
