Recorded operating weight runs from 4,400 to 7,860 kg, wheelbase from 2,553 to 3,050 mm, and top speed of the listed models is 40 km/h. The most powerful models, such as the MF 6497 A and MF 6499 A, marked the top end of the series.
The 6400 series targeted larger arable farms with higher power needs and sat in the AGCO range between the 5400 and 7700 series. For a used model, check the gearbox variant and emissions stage, as these changed considerably over the ten-year production run.
With rated outputs from 66.2 to 158.2 kW, the 6400 series spanned from ISO 730 Category II on the smaller models to Category III on the largest, each with a standard dual-speed power take-off at 540 and 1,000 revolutions per minute. Over the ten-year production run from 2003 to 2013, engine technology moved through several emissions stages, from versions without exhaust treatment to later models with particulate filters or SCR technology.
Massey Ferguson remains part of the AGCO group today, so spare parts for the engine, gearbox and hydraulics of this series run through the existing AGCO parts network.

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.
