Güldner – other models: the collective page of the Aschaffenburg tractors outside the named ranges, from the A series through AFN and ALD to the vineyard and orchard types Burgund, Spessart and Toledo, 12 to 44 kW
This page gathers the Güldner tractors the register could not assign to a named range – from the single- and two-cylinder diesel of the A series to the G types carrying the names of wine- and fruit-growing regions. Güldner, founded by Hugo Güldner in Aschaffenburg, built farm tractors with the marque's characteristic single- and multi-cylinder engines of its own manufacture and was taken over by Linde AG in 1963; tractor production in Aschaffenburg ended in 1969. The A series (A 2 D, A 2 L, A 2 W, A 3 KT, A 3 P, A 4 M) and the numerous short types from ABL to AZK formed the broad post-war programme, the G series (G 15 to G 60) the later generation; some types additionally carried the names of growing regions – Tessin, Burgund, Spessart, Toledo and Gotland – for the narrow-track versions.

The register lists here 34 versions with 11.7 to 44.2 kW (20 to 60 hp) from two- to six-cylinders of 1,305 to 4,712 cm³, unladen weights from 1,115 to 2,750 kg, lengths from 2,635 to 3,955 mm, widths from 1,514 to 1,865 mm, heights from 1,385 to 1,625 mm and rated speeds from 1,800 to 2,300 rpm; all are diesel-powered.
Alongside Fendt, Eicher and Kramer, Güldner was one of the Bavarian tractor makers of the post-war period and was known for its rugged, water- and air-cooled diesels, which also ran as stationary engines. The narrow vineyard and orchard tractors filled a niche in southern Germany and the wine regions along the Main that the large makers barely served.
On used Güldner diesels, engine and cooling condition count – the air-cooled types are prone to cracked cylinder heads if overheated – condition of the injection pump and injectors, transmission and steering, and rust on bodywork and mudguards; spare parts, since production ended in 1969, are only available through specialists and the used-parts market.

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.
- 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.
