In 1964, production of the American-based model 3020 began in Germany. The 3020 was a powerful four-cylinder tractor whose sophisticated technology included a closed hydraulic system and draft control, oil-immersed brakes, a synchronized transmission, and hydrostatic steering.

In 1967 and 1968, the smaller 2020 and 2120 models designed for Europe were introduced. These models were successors to the earlier JD-Lanz 710. New features included an 8+4-speed transmission, which could also be equipped with a hydraulic quick-shift. Other technologies included draft control, oil-immersed disc brakes, and a power take-off independent of the driving clutch. As an optional accessory, a cab equipped with air conditioning was even available. The Sekura cab initially used in Finland, however, was one of the most basic safety cabs. Telescopic draft arm ends were new technology at that time.

In 1969, the top model of the range, the six-cylinder 3120, was introduced. It had 81 horsepower and came standard with a 12+6-speed transmission equipped with a hydraulic quick-shift. The engine was manufactured at a new factory in France.
