All Gehl Ag equipment is falling like a rock. Gehl has stopped making many of the Ag equipment parts already. Many of the parts are hard to get now. So even the later model stuff is loosing value fast.
I know of a guy that had a Gehl chopper that is only five years old and the bracket that holds the sharpener was obsoleted. His broke and we welded it but he sold the chopper as soon as season was over.
Many dealers around me are refusing to trade Gehl equipment in at any price. Many simple little parts are no longer available.
This chopper would not be worth much more than scrap price. I would say $300-500 would be my limit.
