The "late-styled" B represented the final major upgrade to the John Deere model B when production began in February of 1947. The engine size was increased for a third time, and a gasoline-only configuration became available. The frame was now made from pressed steel, and the new padded seat sat on top of a battery box and electric starting and lighting became standard equipment. The Roll-o-Matic front end became available, and the BNH/BWH disappeared as separate models. The BW and BN remained, but now used a convertible front which allow the tractor's front-end to be changed. The rear axle was the key distinction with casting B2405R used for the plain model B, and B2406R used for the BW/BN.
