Renault Ares 600: the strong class before Claas, 110 to 140 hp, six-cylinder diesels throughout at 6,788 cm³, RX and RZ variants
From the mid-1990s, the Ares series covered Renault's more powerful tractors; the Ares 600 tier occupied the upper power segment within it, until the company was gradually sold to Claas between 2003 and 2008 and dissolved in 2008.

The register lists 6 live models, from the Ares 616 RX/RZ to the Ares 696 RZ, built between 1996 and 2005. Output ranges from 81 to 103 kW, or 110 to 140 hp, weight from 5,155 to 6,035 kg, with a constant displacement of 6,788 cm3 and six-cylinder engines throughout.
The RX and RZ suffixes denote different transmission and equipment variants within the same series, a modular approach typical of Renault during these years.
As one of the last large-tractor series developed purely under the Renault badge, the Ares 600 marks an endpoint before full integration into the Claas group.
When buying a used Ares 600, clutch and gearbox condition depending on the RX or RZ specification, the tightness of the lift hydraulics, and the six-cylinder's turbocharger and injection system all matter; rust on cab and mudguards after years of field use is common too. Since the Renault Agriculture brand was dissolved in 2008, parts for the Ares series now run through the Claas parts network. PTO and lift correspond in this power class to ISO 730 Category II to III, at 540 or 1,000 rpm.

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.
