Deutz-Fahr AgroPrima 4.31 to 6.16 – SDF's entry range with four- and six-cylinders: first digit as cylinder count, second as upgrade level, 55 to 81 kW, 3.53 to 4.45 t
AgroPrima, like Agrofarm, is a simple entry range from Deutz-Fahr within the Italian SDF group (Same Deutz-Fahr), designed for price-conscious farms and export markets. The naming logic follows the usual SDF pattern: the first digit gives the engine's cylinder count – 4 for the four-cylinder AgroPrima 4.31, 4.51 and 4.56, 6 for the six-cylinder AgroPrima 6.06 and 6.16 – the second digit orders the range by version and power. The four-cylinders deliver less power than the six-cylinders, as shown by the displacement span from just over 4 to just over 6 litres; fitted are water-cooled Deutz-Fahr diesels with mechanical or part-synchronised gearboxes typical of the simple entry class.

The register lists 5 versions with 54.9 to 81 kW from four- and six-cylinders of 4,086 to 6,128 cm³, torque from 260 to 387 Nm at 2,300 to 2,400 rpm and operating weights from 3,530 to 4,450 kg; lengths range from 4,032 to 4,530 mm.
AgroPrima, like Agrofarm, represents the simple, mechanically oriented side of the SDF line-up and is sold chiefly outside western Europe, where ruggedness and low repair costs matter more than comfort and electronics.
On used tractors, the condition of clutch and gearbox, leak-free hydraulics, rust on body panels, the condition of the front axle on four-wheel-drive versions and parts supply through the SDF network, built out to varying degrees by region, are what count.

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.
