Hey I got and JD450b Just put radiator in it after sitting for 2 years. I cant get the left clutch freed up and not sure if I want to get into doing it. The machine is far from perfect but would make a good farm dozer or for a landowner.
It would probably bring between $2500-$4500 if properly parted out for scrap. Just something to think about. It really depends on the current price of a particular commidty since they change constantly. I know a guy that is parting a Case 450 track loader right now. He is separating everything (cast, brass, aluminum, ...) to maximize his profit.
Any between $4-$6500. Maybe a little more depending on condition.
