Röhr – other models: the collective page of the West German small-tractor maker from Ober-Ramstadt, from 20 R to R 35, two- to three-cylinder diesels of 15 to 27 kW
This page gathers the Röhr tractors the register could not assign to a named range – the West German maker from Ober-Ramstadt near Darmstadt, which in the 1950s built small and medium farm tractors. The type designations 20 R, 24 RA, R 24, R 28 and R 35 combine the letter R with a number; H marks a row-crop version with a narrow track. The engines are throughout diesel units with two to three cylinders.

The register lists here 5 versions with 14.7 to 26.5 kW from two- to three-cylinders of 1,590 to 3,534 cc, unladen weights from 1,295 to 1,890 kg, lengths from 2,480 to 3,120 mm, widths from 1,520 to 1,550 mm and heights from 1,500 to 1,700 mm at rated speeds of 1,500 to 2,000 rpm.
Röhr was one of the many smaller West German tractor makers of the post-war years that, alongside the big brands, supplied regional farming with simple, sturdy tractors; the brand did not survive the market consolidation of the 1960s.
On the rare Röhr tractors, what counts today is above all the preserved condition of the engine and bodywork, since parts are practically no longer found through regular trade; buyers check the compression and oil loss of the old diesel engines, the condition of hydraulics and brakes, and the completeness of attachments and data plate, as many machines were dismantled or rebuilt over the decades.

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.
