Renault MX: the bridge to the 1990s series, around 70 hp, three- and four-cylinder diesels on the LS and RS engine base, the last numeric type range
The MX series followed the TX, RS and LS in the late 1980s and formed Renault Agriculture's last tractor generation before the introduction of the new naming family — Ceres, Temis and Ares — in the early 1990s.

The register lists 10 live models, from the 58-12 MX to the 90-34 MX, built between 1988 and 1993. Output ranges from 39.7 to 61.1 kW, or around 70 hp, weight from 2,555 to 4,335 kg, displacement from 3,117 to 4,156 cm3, across three- and four-cylinder engines.
Technically, the MX series drew on the same engine family as the preceding LS and RS series, but combined it with reworked hydraulics and cab as a final development step before the wholesale model renewal.
The MX series thus marks the end of numeric type designations at Renault Agriculture, before the 1990s series introduced proper model names.
When buying a used MX series, clutch and gearbox condition, the tightness of the reworked lift hydraulics, and rust on cab and mudguards after decades of use matter; since the engine and displacement are identical to the LS and RS, common wear parts are widely available. Parts have run through the Claas parts network since Renault Agriculture's dissolution. PTO and three-point hitch correspond in this power class to ISO 730 Category I to II, at 540 rpm. As the category rises, the lift-arm pin diameter grows too, which can make older, lower-category implements incompatible.

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.
