Always keep a razor-sharp Chipper Knife Kit on hand, as your chipping knife will dull over time. With a replacement knife nearby you can install the new, sharp knife and continue working.
Because our knives are made of high-carbon/high-chromium forged alloy tool steel, they can go significantly longer than the knives on most “bargain” chippers without sharpening. Still, as with any cutting tool, keeping a sharp edge is important for maintaining peak performance. When the chipper starts to “bog” down, and/or vibrates and requires that you regularly force the material downward into the chipper chute, it’s usually a sign that the knife is dulling. Many customers choose to get an extra knife to have on hand. That way, you can keep working with a minimum of downtime.
This Knife Kit is for the PRO XL575 (21.00 FPT) DR Self Feeding Chippers manufactured in 2015 or after.
The replacement DR Rapid-Feed Chipper Knife Kit comes with all the necessary hardware.
Hardened steel knife
Please Note: Proper knife to wear plate gap is important; it should be 1/16″. Please refer to your owner’s manual for sharpening and installation instructions. Please call us toll-free 1-800-687-6575 if you have questions about your DR.
TIP: If chipping a lot of soft wood (pine, spruce etc.), and pitch build up is observed on the knife, it is recommended to occasionally chip some hard wood to clean the pitch off the knife.
