Someca GRANDI 80 series – the big six-cylinder tractors of Fiat's French subsidiary, types 1180 TD to 1880 TD, 85 to 132 kW from 5.5 to 8.1-litre engines
Someca, Fiat's French subsidiary for farm equipment, launched its big six-cylinder farm tractors with the Grandi range of the 1980s. The types 1180, 1280, 1380, 1580 and 1880 all carry the TD suffix and are fitted with six-cylinder diesel engines of 5.5 to 8.1 litres.

The register lists here 5 versions with 84.6 to 132.4 kW from six-cylinders of 5,496 to 8,102 cc, unladen weights from 4,677 to 6,500 kg, lengths from 4,095 to 4,365 mm, widths from 2,000 to 2,160 mm and heights from 2,745 to 2,865 mm, torque from 390 to 684 Nm at rated speeds of 2,100 to 2,550 rpm.
The Grandi range formed the top of the Someca programme in the 1980s for big arable farms in France; with the end of Someca as an independent brand, these big tractors later merged into Fiat group's joint Fiatagri programme. Someca thus competed directly with the big six-cylinder tractors of Renault, Fiat and the German brands of the time.
On the big Someca six-cylinders, what counts is the condition of the clutch and shuttle transmission on these heavy machines, the tightness of the hydraulics and lift, the compression and cooling system of the six-cylinder diesel, and rust on the cab and mudguards; parts run through the CNH network, into which the former Fiat and Someca organisation merged, as well as the function of alternator and starter motor.

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.
