Ensinger AS – the small tractors AS 20 and AS 20i: two-cylinder diesel of 2,356 cm³, around 22 hp, unladen weight 1,390 to 1,650 kg
Ensinger was a German maker of small farm tractors whose AS range covered types for smaller and medium-sized holdings. The AS 20 and AS 20i carry the approximate output in metric horsepower in their designation; the i suffix on the AS 20i denotes a revised or differently equipped version of the same base model. Both types share a two-cylinder diesel engine of identical design.

The register lists here 2 versions with around 22 hp from two-cylinder diesel engines of 2,356 cm³ displacement, with unladen weights from 1,390 to 1,650 kg and rated speeds from 1,500 to 1,600 rpm.
Ensinger was one of the smaller German tractor makers in the highly diversified post-war industry, where numerous regional suppliers served smaller farms alongside major brands such as Deutz, Fendt and Hanomag. The AS range targeted exactly this segment of small and medium-sized farms. Many such marques disappeared from the market already during the 1960s and 1970s, as industry consolidation left room mainly for the largest makers.
When buying these rare small tractors, condition and originality matter most: engine bearings, injection pump and compression of the two-cylinder unit, rust on panels and mudguards, the condition of steering and brakes, and the tightness of the hydraulics. Spares today can practically only be sourced through collectors and tractor clubs.

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.
