Güldner G Series – Main Series of the Aschaffenburg Builder, 1962 to 1969: two- to six-cylinder engines with 11 to 47.6 kW (15 to 60 hp), 885 to 4,712 cm³ displacement
The G series was the main line of the tractor manufacturer Güldner, based in Aschaffenburg, and covered a wide power spectrum from 1962 to 1969. According to the register, output of the recorded models ranges from 11 to 47.6 kW, with models rated in horsepower from 15 to 60 hp, using two- to six-cylinder engines with displacement from 885 to 4,712 cm³.

Recorded operating weight runs from 890 to 3,985 kg, wheelbase from 1,650 to 2,416 mm, and top speed of the listed models spans 19.4 to 26.22 km/h. Models with the S suffix denoted a synchronised gearbox.
The G series was the manufacturer's broadest range until Güldner ended tractor production in 1969, spanning compact models such as the G 15 to large variants such as the G 75. For a used model, the exact engine matters most, as output and cylinder count differ considerably within the series.
A synchronised gearbox, as fitted to the S models of the G series, allows shifting between adjacent gears without an intermediate clutch action and without the extra throttle blip needed on unsynchronised gearboxes, easing gear changes during field work. Across the entire power range of the G series up to 47.6 kW, the three-point hitch stayed within category I under ISO 730, and the PTO ran at 540 rpm. Parts for the G series are today mainly available through specialist Güldner and vintage-machinery dealers.

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.
