demoed one., would not get up to rpm's to cut efficiently. BS answer from dealer about the problem. I like Subaru, have some on some snow blowers, but this combo was just not working.
I have a client with a Camperdown Elm that I take care of. You are not going to find a replacement for it. They are grafted. I haven't seen any for sale in 25 years. Get them into a maintenance program = $$$.
3 k to 4k is a really huge difference in chipper hours. Sounds like they are being vague on purpose. Personally, I would not be interested in this unit with that many hours.
You have to rewind the spring. Pull the starter cord all the way out and wind the spring opposite direction of the way it rotates when it is pulled to start the blower. Do about 6 rotations, then slowly let it rewind and feed the cord in.
