MF 300: solid mid-range of the late 80s and 90s, 47 to 90 hp, three-, four- and six-cylinder diesels, also built under licence in Brazil and South Africa
From the late 1980s, the 300 series took over the 200 series' role as Massey Ferguson's mid-range class and stayed in the catalogue into the late 1990s, alongside the newer 3000 and 4200 series in the upper segment.

The register lists 15 live models, from the MF 340 (A) to the MF 390 (A), built between 1987 and 1998. Output ranges from 30.9 to 71.4 kW, or 47 to 90 hp, weight from 2,324 to 3,600 kg, displacement from 2,500 to 5,806 cm3, across three-, four- and six-cylinder engines.
Like its predecessors, the 300 series spanned a broad power range from a compact three-cylinder up to a six-cylinder flagship, and was built under licence worldwide, including at plants in Brazil and South Africa.
As a rugged, technically straightforward mid-range line without complex electronics, the MF 300 ranks today among the sought-after used tractors for smaller operations.
When buying used, check clutch and gearbox condition – mechanical or with powershift stages depending on specification –, the tightness of the lift hydraulics, and rust on cab and body panels; on examples built under licence in Brazil or South Africa, specification can differ slightly from the European version. Parts today run through the global dealer network of the AGCO group, which Massey Ferguson belongs to. The mechanical and powershift versions of this series share the same base engine, so many wear parts are interchangeable between the two variants.

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.
