Roll-O-MaticIntroduced in 1947, the John Deere Roll-O-Matic system offered a smoother ride than a traditional narrow front end. It is similar to a semi-independent front suspension. When one wheel hit a bump, a gear would force the other wheel down, keeping it in contact with the ground. This would prevent the tractor from hopping, as would occur on a typical tricycle-front tractor. |
