I've spent the last two days clearing cedar fence lines. The chipper is mounted on a 4300 John Deere and is working great. I was very pleased the way the gravity feed works, I wasn't sure how much effort it would take to feed it, but my (adult) daughter was helping me and she was able to feed it just fine, while I was cutting and dragging.
I have used larger chippers before that didn't chip nearly as well I think the angle of the blade mounts on the rotor help it.
Looking forward to years of use, thanks for the help.
