1938 John Deere Model B.

1938 John Deere Model B. Keystone Truck & Tractor Museum, Colonial Heights, Va. The John Deere Model B was introduced as a smaller tractor, to fill the needs of row-crop farmers who did not need a tractor as large as the A. It had a nearly 20-year production run, and the versions of the B can be broadly divided into three groups. The original B is often referred to as “unstyled,” and includes all tractors built through 1938. In 1939, with tractor number 60000, the “early styled” Model B was introduced.

In mid 1947, with tractor number 201000, the “late styled” Model B began production.
