Güldner AF – field tractors from Aschaffenburg of the 1950s: twin-cylinder diesels at 1,304 to 2,598 cc, 12.4 to 22 kW, types AF 15, AF 20, AF 30 and AF 30 P
Güldner built the AF series in the 1950s at its home site in Aschaffenburg; the company had previously been known mainly as an engine maker before turning increasingly to tractor building. The four types AF 15, AF 20, AF 30 and AF 30 P are ordered by ascending power through the type number, with the P denoting a special version. In 1961 the hydraulics group Linde took over Güldner's tractor division. Before the Linde takeover, Güldner was regarded as a technically accomplished German engine maker, which was also reflected in the construction of the AF tractors.

The register lists 4 versions with 12.4 to 22 kW from consistently twin-cylinders of 1,304 to 2,598 cc displacement at 1,500 to 1,800 rpm. Unladen weights lie between 1,225 and 2,040 kg, lengths between 2,650 and 2,920 mm, widths between 1,578 and 1,640 mm, and heights between 1,500 and 1,680 mm.
The AF tractors were aimed at small and medium farms in West Germany during the post-war reconstruction period and competed with similarly positioned brands such as Fahr, Eicher and Hanomag, which at the time likewise had compact twin-cylinder diesels in their range.
On a used purchase of such a Güldner classic, check the condition and tightness of the twin-cylinder diesel, wear on the clutch and mechanical gearbox, and corrosion on sheet metal and the frame; parts are now only available through specialists and tractor exchanges.

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.
