Nordtrak Stier series: compact small tractors in four versions from ST 45 to Stier 30, 11.8 to 29.3 kW from one- to three-cylinder engines of 1,470 to 2,360cc, 1,530 to 2,500 kg kerb weight
The Stier series brings together in the register a compact small tractor in four versions: ST 45, Stier 18, Stier 25 and Stier 30. These are one- to three-cylinder diesel tractors in the lower power segment, used on small farms, in orchards and vineyards and for municipal tasks; the short wheelbase and narrow track suit work in confined spaces. The narrow track also eases manoeuvring around farm buildings and through narrow gateways.

The register lists 4 versions with 11.8 to 29.3 kW from one- to three-cylinder engines of 1,470 to 2,360cc, kerb weights from 1,530 to 2,500 kg, lengths from 2,600 to 3,290 mm, widths from 1,600 to 1,690 mm, heights from 1,700 to 1,875 mm and a rated speed of 1,500 rpm.
In this power segment, small tractors such as the Stier series compete with Asian compact tractors and smaller ranges from European manufacturers designed for grassland maintenance, transport work and work between row crops. Many such small tractors also found their way into equipment rental fleets serving smallholders.
When buying used, check operating hours, clutch and gearbox condition, diesel engine oil-tightness and corrosion on the chassis and bodywork; for such small and older series it is worth checking parts availability before buying, as distribution networks for small tractors are often regionally limited.

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.
