The PRO 475 features our DR Self-Feeding design that will let you tear through branches up to 4.75" in diameter without bogging down. A vertically oriented hopper, precisely angled chipping knife and powerful air channel draw materials in and spit them out the chute.

• Easy-Pull Start! The 11.5 HP (16.5 ft-lbs gross torque*) Briggs and Stratton OHV engine easy-pull, manual-starting option will almost always start on the first pull.
• 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 (17" x 27") accepts 4.75" branches with little or no trimming of side branches.
• Road Towing Modify the optional road tow package and you can easily tow your Chipper on roads at speeds up to 45mph.
• 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 PRO 475 Chipper uses a durable 420cc Overhead Valve engine with your choice of manual- or 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 PRO 475 features a 17.75" diameter flywheel that weighs a hefty 50 pounds. It spins at 128 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.
