Renault LS: the compact entry class of the mid-1980s, 54 to 78 hp, three- and four-cylinder diesels on the same engine base as the RS and TX
The LS series filled out Renault's line-up in the mid-1980s with a more compact entry class below the TX and RS, with noticeably lower weight on a similar engine base.

The register lists 8 live models, from the 58-12 LS to the 85-14 LS, built between 1985 and 1989. Output ranges from 39.7 to 57.4 kW, or 54 to 78 hp, weight from 2,640 to 3,600 kg, displacement from 3,117 to 4,156 cm3, across three- and four-cylinder engines.
Despite sharing the same displacement base as the RS and TX, LS models consistently weigh less, pointing to simpler cab and chassis specification aimed at smaller and mid-sized farms.
Renault thus positioned the LS series as an affordable route into its engine technology, without the comfort and equipment scope of the larger series.
When buying a used, lighter LS series, clutch and mechanical gearbox condition, the tightness of the lift hydraulics, and rust on the simpler cab and mudguards matter; since the engine and displacement are identical to the RS and TX, parts for the injection system and cooling are widely available, though cab- and chassis-specific parts are scarcer. Parts have run through the Claas parts network since Renault Agriculture's dissolution. PTO and three-point hitch likewise correspond in this power class to ISO 730 Category I to II, at 540 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.
