Renault R-50 Vigneron (1968-1976): air-cooled two-cylinder vineyard tractor with 24.3 kW output and a width of only 890 mm from the 50 series
Under its 50 series, Renault built narrow specialist tractors for vineyard work, as the Vigneron designation in the model name already indicates. The R-50 Vigneron was built from January 1968 to October 1976 and belongs to the narrow-track special versions of the brand.

The air-cooled two-cylinder diesel engine displaces 1,701 cm³ and delivers 24.3 kW at 2,150 rpm, equivalent to 33 horsepower. At only 890 mm wide, with a weight of 1,430 kg and a wheelbase of 1,680 mm, the R-50 was tailored to the narrow row spacing of vineyards, with a top speed of 25 km/h.
Narrow-track vineyard tractors must be able to turn between rows of vines that often leave little more than a metre of space, so their overall width was noticeably smaller than that of standard tractors of the same power class. The air-cooled design needed no radiator, saving space in the narrow engine bays typical of such vineyard tractors.
When buying a used R-50 Vigneron, the cooling airflow around the cylinder should be checked, as it is especially prone to fouling behind the tight bodywork of vineyard tractors. The steering and tyres also deserve attention, since frequent work between vine rows with tight turning manoeuvres puts more strain on the steering linkage and tyre sidewalls than straight fieldwork. Fender clearance should be checked too, since narrow vineyard bodywork is easily bent by contact with posts and end stakes.

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.
