The John Deere model B was introduced as a smaller tractor, to fill the needs of row-crop farmers that 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, began the “early styled” model B. In mid 1947, with tractor number 201000, began the “late styled” model B. Within the first year of production, tractors number 1000 through 3042 used a four-bolt front pedestal.
