Renault S series – tractors 461 S and 751(-4) S from Le Mans, 34 to 55 kW, three- and four-cylinder engines of 2,827 to 4,156 cm³, some with MWM engines
The S series belongs to Renault Agriculture's classic tractor programme, built at the Le Mans plant in France; the types covered here, 461 S, 751 S and 751-4 S, show the four-digit type number typical of Renault's size ordering, while the 4 suffix on the 751-4 S marks four-wheel drive. For one model in the range the register records an engine from the maker MWM, used alongside Renault's own units.

The register lists here 3 versions with 33.9 to 55.2 kW, or 46 to 75 hp, from three- and four-cylinder engines of 2,827 to 4,156 cm³, torque from 175 to 266 Nm, unladen weights from 2,034 to 3,640 kg, lengths from 3,449 to 4,031 mm, widths from 1,610 to 1,860 mm and heights from 2,360 to 2,595 mm.
With this power range the S series covered the mid-range segment of the Renault line-up and competed with the French and European mid-range tractors of the era, such as those from Massey Ferguson, Fiat and Deutz; the four-wheel-drive 751-4 S extended the field of use onto more demanding terrain.
On a used S-series tractor, the condition of the clutch and gearbox, rust on the chassis and sheet-metal panels, and the tightness of the hydraulics all count, and on the four-wheel-drive version also the condition of the front-axle gearing and drive shafts; parts for Renault's own engines must be sourced through specialist farm-machinery dealers.

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.
