| The John Deere model 730 replaced the 720, offering cosmetic upgrades. A notable option were the deluxe flat-top fenders with headlights. Front-end options on the row-crop 730 were single wheel, conventional or Roll-O-Matic dual front, or adjustable wide front. The John Deere 730 diesel (along with the 720) held a 27-year fuel economy record for most efficient diesel tractor at the Nebraska Tractor Test Laboratory. | |
