Holder A series – the articulated tractors from Metzingen for vineyard and orchard: A 8 to A 50, the number as hp class, Cultitrac as the smallest tractor, S as upgrade, B, F and D for petrol, bought-in engine and diesel
The A series made Holder of Metzingen the inventor of the articulated narrow-track tractor: at the end of the 1950s the company presented with the A 12 Cultitrac a tractor that steers with four equal wheels, four-wheel drive and a pivot in the middle – narrow enough for the vineyard row, agile enough for the orchard, and with the articulation principle that keeps all wheels in the same track. The type logic: A marks the range, the number the hp class – A 8 about 8 hp, A 12 12 hp, A 20 20 hp, A 45 about 45 hp, A 50 50 hp – Cultitrac the smallest models, S an upgrade, and on the A 8 the letters B, F and D distinguish the petrol engine, the bought-in engine and the diesel. The engines are a single-cylinder two-stroke in the smallest, one- to three-cylinder diesels in the other models of 0.4 to 2.4 litres at rated speeds of 1,800 to 3,000 rpm.

The register lists 8 versions with 5.9 to 37 kW from engines of 372 to 2,356 cm³, unladen weights from 635 to 1,560 kg, lengths from 1,950 to 3,200 mm, widths from 700 to 1,190 mm and heights from 1,010 to 2,015 mm.
The Holder articulated tractor became the standard of German steep-slope viticulture on the Moselle, Rhine and Neckar and shaped a whole class that Fendt, Antonio Carraro and Holder itself serve today; the A series ran into the 1980s.
On used tractors, play in the articulation joint and steering cylinders, the condition of engine, clutch and gearbox, PTO and hydraulics for sprayer and mulcher and parts supply, which runs through Holder and vintage specialists, are what count.

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.
