Hanomag RC – small-tractor range from Hanover: types R 22 to R 435 RC, three- and four-cylinder diesels of 2,099 to 2,799 cm³, 16 to 26 kW, unladen weights of 1,520 to 1,945 kg
Hanomag, the Hannoversche Maschinenbau AG headquartered in Hanover, built a range of small tractors under the R designation in the 1950s for smaller and medium-sized farms. The types R 22 RC, R27 RC, R28 RC and R435 RC recorded in the register carry the company's typical number-letter combination, in which the number indicates the approximate power class.

The register lists 4 versions with 16 to 26 kW from three- and four-cylinder diesel engines of 2,099 to 2,799 cm³ displacement, unladen weights from 1,520 to 1,945 kg and an overall height of 1,760 mm throughout; lengths range from 2,990 to 3,310 mm, widths from 1,580 to 2,040 mm, rated engine speeds from 1,500 to 1,900 rpm.
Hanomag's R-range small tractors competed directly with comparable ranges from Fendt, Deutz and Normag in the 1950s and were aimed at operations seeking a manoeuvrable, sturdy tractor for field and yard work without the purchase cost of a large field tractor.
On a used R-range Hanomag, rust on the frame and sheet-metal parts, the condition of the diesel engine's injection pump and injectors, the tightness of the hydraulics and lift linkage, and the condition of the axles and steering after decades of use all count; because production ended long ago, parts are mostly only available through specialist secondhand-parts dealers and salvaged vehicles.

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.
