The 483, 583, 613, 683, and 684 models, introduced in 1982, served as the basic tractors for the long-term positions of the R 503 and 603. There were many series of air-cooled engines: the smallest ones originated from predecessors, and the 3.1-liter Same engine had previously been used in Lamborghini crawler tractors. The four-cylinder engine in the 684 was the same as in the heavier models 654 and 754. The 653 differed from the series in design: its front end resembled that of the 654.

The transmission was the previous fully synchronized 12+3, but the gear ratios were adjusted for higher speeds to achieve a highway speed of 30 km/h. Steering was hydrostatic in most models, and the brakes were oil-bath type.

The lineup was reduced in 1985, but the 613 and the newly introduced 714—which featured a newer 4.0-liter engine from the 1000 series—continued production until 1989.

The production years of the models are approximate.
