Someca Gold Ribbon: the Fiat range built for export, from the Someca 250 (DT) to the 1300 SUPER (DT), 18.4 to 106.6 kW, two- to six-cylinder engines with water cooling
After 1965, Someca built only Fiat designs under licence. The "Gold Ribbon" range, created for export markets, particularly Britain, bundled these Fiat-based models of the late 1960s and 1970s under Someca's own name and trim.

The register lists 36 live models, from the Someca 250 (DT) to the 1300 SUPER (DT), built between 1968 and around 1983. Output ranges from 18.4 to 106.6 kW, weight from 1,070 to 5,650 kg, displacement from 1,559 to 7,412 cm3 across two-, three-, four- and six-cylinder engines.
The Gold Ribbon range thus covers practically the entire Fiat-Someca power spectrum of those years, from a compact two-cylinder up to the large six-cylinder 1300 model. Technically, these tractors largely match the equivalent ranges sold in parallel under the Fiat name.
In 1983 Someca was fully absorbed into the Fiatagri division, which became Fiat New Holland in 1993 and later CNH Global — an endpoint that closes out the Gold Ribbon era.
The huge power spread from 18.4 to 106.6 kW means several categories of the ISO 730 three-point linkage occur within the Gold Ribbon range: the small two-cylinder models mostly Category 0 or I, the large six-cylinders already Category II. On a specific example, the actual hitch category should therefore be checked before buying new implements, rather than relying on the model name alone.

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.
- Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
- 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.
