| | Comments: |
| |
| The BR (regular) and BO (orchard) were the fixed tread version of the row-crop model B. While the row-crop B continuted in production until 1952, the BR/BO was replaced by the model M in 1947. The BO had differential brakes (one for each rear wheel) as standard equipment. While a service brake (one for both wheels) was originally standard on the BR, differential brakes became an option. |
