Info

Decorated with yellow decals, the John Deere 720 received a new gasoline engine compared to the Model 70. However, sales soon shifted in favor of the diesel version. The 720 Diesel was, for its power output, the most economical diesel tractor tested in Nebraska before the 1980s. The transmission was now operated with a single lever. First gear was noticeably slower than before. The brakes were larger. The three-point hitch now had a draft-control system and external lift cylinders. The auxiliary hydraulic couplers could now be hooked up under full pressure. The 720 was offered in both a standard version and a row-crop version, which at the time was the most powerful narrow-front-axle tractor available.

There were few changes from the Model 80 to the 820. The brakes were bigger and the power steering was improved. As an option, a new steel cab could be added. For 1958, engine output was raised to 75 horsepower.
