Product details:

A dedicated self-feeding chipper that will power through branches up to 4.75 In. diameter. Pin hitch included standard and road towing optional. 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.
