Got my chipper back together. When into self destruct mode the other day. All the nuts on the chute loosed up and lost half of them. Replaced with nyloks. While I had the chute off I sharpened the blades a. Actually not in bad shape considering I don't think they were ever sharpened. Must be good steel. Need to check around for a new chute. Its plastic and I think some critter got trapped in there and chewed a hole in the bottom to get out. If I cant find it or too much $, I could plate it with some metal, but might get in the way of sticks going in.
