My cousin has a 50's John Deere 440 dozer that has been sitting for 20 years with a broken final drive and a tarp over it. The machine is pretty rusted up. I would like to get it going again but it seems like a running machine is around $3000-4000 on ebay. I'm pretty sure it's a gasoline engine. What should I offer for it and how much do you guys think it would cost to get running again? Should I just suck it up and buy an already running unit?
It looks like this but rustier:

I restore vintage tractors (1940s, 50s, 60s)--a lot smaller in size that that dozer, but the issues are the same:
-- Do you have equipment of your own (or maybe a friend's) to transport the dozer and any heavy replacement parts to your shop?
--Can you handle the restoration yourself and/or with the help of friends who'll work for beer and pizza?
-- Do you have a shop with suitable equipment (hoists, cranes, jacks, jack stands, etc) that can handle the heavy stuff?
-- Have you identified a source of replacement parts (new, new old stock, used, etc)?
If you answered no to any of these questions, forget about it. You'll be wasting your time and money.
If you really, really want a dozer, find one that's running, that hasn't been rusting away in the rain for 20 years, and spend your money wisely.
