The Fiat 312R is a tractor built in 1965. Power comes from a four-cylinder engine; from 1.9 litres it draws 22.3 kW.
It measures 2.83 m in length and 1.47 m in width. Empty, it weighs 1,420 kg.
Within the range, rated power spans from 14 to 280 kW; with 22.3 kW, the 312R sits at the bottom end. Directly alongside are the Concord U25 with 19 kW below and the Concord 350 with 26 kW above.
Fiat – other models: from the small 18 La Piccola to the 1984 "-90" generation, 14 to 280 kW, Cummins and Fiat's own engines, "-C" marking crawler versions
This collective page brings together Fiat tractors outside the named series, from early small tractors such as the 18 La Piccola to the large four-wheel-drive tractors of the 1980s. Fiat had built farm machinery in Turin since the 1910s; the type designations of the 1980s generation follow a power-class-plus-year pattern, such as 100-90 or 180-90 for the "-90" series introduced in 1984. The "-C" suffix (300, 312-C, 331-C) marks crawler versions (cingolato) for steep or poorly load-bearing ground. In 1991 Fiat's tractor division merged with Ford New Holland to form New Holland, and the Fiat brand disappeared from tractors during the second half of the 1990s.

The register lists 216 versions from 14 to 280 kW with three- to six-cylinder engines of 1,135 to 14,016 cm³, unladen weights of 830 to 11,061 kg and gross weights up to 10,000 kg. On the largest models, Cummins units from the NT-855 range were fitted alongside Fiat's own engines.
Alongside Massey Ferguson, International Harvester, Ford and Renault, Fiat ranked among Europe's major tractor makers and led the market in Italy, France and Spain. The switch to the New Holland brand in the late 1990s ended eight decades of independent Fiat tractor production, though many design principles lived on in New Holland ranges.
When buying, check the hydraulic pump, the PTO clutch, and on four-wheel-drive models the front axle; older Fiat models with a Cummins engine are worth checking for cooling and turbocharger condition. On crawler versions (-C), the undercarriage, track tension and roller bearings are the critical wear points. Spares now mostly flow through the New Holland network, since both brands share the same design lineage.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Shift the gearbox cold and warm — jumps only show up at temperature.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
