John Deere 70 replaced the earlier model G in the spring of 1953. The gasoline engine now had a quarter more power than before, moving the 70 into the 50-horsepower class. The 70 also featured a two-barrel carburetor. The transmission was 6+1, and unlike the smaller models, it was still operated with two levers. As an option, power steering and a power take-off independent of the driving clutch were available.

In the fall of 1954, the 70 Diesel was introduced. Its power was roughly the same as the larger R model, but it weighed less and the 70 was also offered as a row-crop version. Instead of the R model’s two-cylinder gasoline starter engine, the 70 Diesel had a V4 gasoline engine. However, Deere stuck with a two-cylinder design in the diesel models as well, even though switching to diesel would have been the perfect time to move away from the traditional two-cylinder layout based more on rationale than practical reasons.

The largest model was the last to switch to the numbering series, when the R Diesel was replaced by the 80 in the summer of 1955. Power was increased in this model as well, and it also had a 6+1 transmission. The hydraulic pump was now powered directly by the engine. The starter motor in the 80 was also a V4. The 80 was a short-lived model, as the entire series was renewed the following year.
