The Oldest Tractor? Hart-Parr 22-45

Hart-Parr 22-45 owner marks the centennial of what may be the oldest purpose-built tractor in the U.S.

Jerry Swedberg's Hart-Parr. The Hart-Parr doesn't see much work any more. "I don't work hard and it shouldn't either," Jerry says with a laugh. "If you tore off a bearing on that old machine, or you screwed it up in some other way, you'd never forgive yourself."
