To get the best chipping performance from your DR, the chipping knife will need to be sharpened occasionally.
With a replacement knife on hand you can install the new, sharp knife and continue working, and then take some time later to sharpen the dull knife.
The Knife Kit includes installation hardware and fits all DR Leaf and Lawn Vacuum models with a built-in chipper and our 11.5 ftp Chippers with Shredders.
