DR Wood Chipper + Spare Knife Kit for DR Self-Feed Chipper + Maintenance Kit for $3,000 OBO. Current cost of chipper and kits new is $4,170, so this is a savings of $1,170.

We purchased a new wood chipper, its knife kit, and maintenance kit in early January 2016. After being used for one project, we find we do not need the equipment any longer. Along with the specs listed below, the chipper comes with a cover and a chain lock to secure it on your own property.

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!
