Depends on how many models were made, and how many of those parts would fit on other models. I had a customer do some trading with me on a
big Craftsman lawn tractor with a blown Kohler engine. I started by parting out the engine on E-Bay, thinking that I would find an engine for the tractor,
eventually parted that out, piece by piece, eventually got @ $1800 or so out of it. Sold the real big stuff like the hood and deck on craiglist.
But in your case, there are not that many folks out there with a zmaster.
