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.

This is one of the earliest Hart-Parrs, sold in 1902. There are a few similarities between this one and Jerry Swedberg‚Ã"ôs 1906 model, especially in the finned radiator at back.
