You may be aware of this but about half the wood chippers manufactured in this country are made in your state- seems like there ought to be some deals on 'em nearby. They do show up here periodically so maybe a member will have what you need. Mine isn't for sale-I need to move up to a bigger model but that will have to wait due to financial constraints.
I have a 1989 Morbark eager beaver 12" chipper with Cummins Diesel engine. New cutter shaft and bearing,sandblasted, paint and decals. Runs and looks like new, about 1200 hrs on meter.$8,500.
