Someca 580-980: the last generation before Fiatagri, from the 580 (TD) to the 980 (TD), 42.7 to 72.1 kW, three- to six-cylinder engines with water cooling
The 80 series was Someca's last major range marketed as an independent brand before the company was fully absorbed into the Fiatagri division in 1983. It too was based on Fiat designs, finished in Saint-Ouen for the French market and sold under the Someca name.

The register lists 6 live models from the 580 (TD) to the 980 (TD), built between 1975 and 1983. Output ranges from 42.7 to 72.1 kW, weight from 2,335 to 3,845 kg, displacement from 2,750 to 5,178 cm3 across three-, four-, five- and six-cylinder engines.
The type designations match the 580-980 models sold in parallel under the Fiat badge — a fundamentally sturdy mid-range line with a growing engine offer, up to the five-cylinder fitted in the 880-5.
When this series ran out in 1983, independent marketing under the Someca name ended too; model development passed to Fiatagri from then on.
With operating weights of 2.3 to 3.8 tonnes, the 80 series spans the transition from Category I to Category II of the ISO 730 three-point linkage; lighter models such as the 580 and 680 are usually still Category I, the heavier 880 and 980 already Category II. When buying used, it is therefore worth matching the lower links and hooks actually fitted to the implements on hand before investing in new adapters. The category difference also affects the hydraulic lift capacity needed for heavy implements.

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.
