I'm looking at a 77 Oliver that someone who has major medical issues is trying to sell. Has new rear tires, older restoration but no lights or generator. Has distributor, battery, and starter so not sure why no generator. Used only for parades so that is probably the reason. Has PTO issues but owner has parts to fix it. Runs good and looks good, has the engine panels in great shape. What's it worth? Any thoughts about what to look for would be appreciated. I'm a John Deere antique restorer but have also loved the looks and sounds of the Oliver tractors. It's green so it will look good in the machine shop with the Deere's.
