I did a search on the fan issues, that will be the first thing I check Monday morning and something i could repair myself. If it is busted which is highly likely, maybe I will have a little negotiation advantage. The plastic, unless someone locally was parting out same unit I seriously doubt I'd ever find a replacement parts.
I'm pretty good at haggling so if the tractor checks out mechanically as in engine, 4wd, trans etc I'm dragging it home. Thanks for all the comments, hopefully I'll post a pic of the rig on the trailer Monday !
