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.

A banner proclaiming the 100th anniversary of Jerry Swedberg's Hart-Parr 22-45 was draped on the machine at the Western Minnesota Steam Threshers Reunion at Rollag, Minn., where it was shown in 2006. Note the double tank for gasoline and kerosene.
