The Werner UK Uniknick – a German articulated tractor: the UK52 and UK60, a four-cylinder 2,440 cm³ diesel, 60 hp, 5,100 kg unladen weight
The Uniknick from Werner UK is an articulated tractor of German origin, in which the front and rear sections steer against each other through a central joint instead of a steered front axle – a design principle aimed chiefly at tight manoeuvrability in confined space. The register lists the UK52 and UK60 versions here, which largely match in their recorded technical values and differ mainly in their type designation.

The register lists 2 versions with 60 hp from four-cylinder engines of 2,440 cm³, an unladen weight of 5,100 kg, a length of 5,530 mm, a width of 1,920 mm and a height of 2,550 mm, both with a diesel engine.
Articulated tractors such as the Uniknick occupied a niche between classic farm tractors and construction machinery: their tight turning circle made them interesting for work in confined conditions, such as municipal service or smaller, awkwardly shaped plots, where a tractor with a steered front axle would have needed a markedly wider turning radius. Compared with classic farm tractors, though, the design remained a niche solution built in comparatively small numbers.
On used examples, the condition of the articulation joint and its bearings, the tightness of the steering hydraulics, the state of clutch and gearbox, and rust on the frame and sheet-metal parts all count; spare parts for this rare design are scarce and run mostly through collectors and workshops specialising in articulated vehicles.

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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
