Smaller new models had to wait until 1978, when the 580 and 680 were introduced. The smaller one had a 2.75-liter three-cylinder engine, and the larger one had a 3.5-liter four-cylinder. The 580 had an 8+2 gearbox, while the 680 had a 12+3, as did the 780. In the gearboxes, half of the gears were still synchronized (in the 12-speed: 3, 4, 7, 8, 11, and 12). The 780 had also received a slightly more powerful hydraulic pump.

However, the most significant novelty was the Pininfarina cab made from pressed shaped panels, which was manufactured at Ferrari's factory in Modena. The cab was one of the quietest of its time (82.5 dB), but quite cramped.

In autumn 1980, the tractor's color was changed to a darker shade. At the end of 1981, road speeds were increased from 26 to 30 km/h, and the front axle was replaced with a more agile one equipped with an automatic differential lock, except on the 580. At the same time, the cab's central pillar was narrowed, the hood reshaped, the grille made detachable, and the headlights changed to square ones. Additionally, the hydraulic outputs were increased.

At the beginning of 1983, the gearbox was changed to fully synchronized.
