More about the John Deere B

The first John Deere B Tractors went out of the factory gates in 1935 and they kept building them until 1952. Sometimes, the parts compatibility is determined by the serial number of your John Deere B Tractor, and that info should be listed on the part fit notes. If you don't have the serial number of your tractor, you can find it on the the left side of the transmission case, under the governor. The serial number starts from 1000 for a 1935 model, from 12012 for a 1936 model, from 27389 for a 1937 model, from 46175 for a 1938 model, from 60000 for a 1939 model, from 81000 for a 1940 model, from 96000 for a 1941 model, from 118721 for a 1942 model, from 136315 for a 1943 model, from 149219 for a 1944 model, from 167700 for a 1945 model, from 179788 for a 1946 model, from 191303 for a 1947 model, from 209295 for a 1948 model, from 230044 for a 1949 model, from 253025 for a 1950 model, from 275242 for a 1951 model, from 293030 for a 1952 model, from 310772 for a final model. They also have differential mechanical expanding shoe brakes. The 3-point hitch is very reliable. It is also worth noting that the transmission rear PTO runs at 540 rpms.
