Steyr Plus series: forerunner of the 8000 generation, from the 430 to the 1400 a, 23.6 to 103 kW, two- to six-cylinder engines with water cooling
Before Steyr-Daimler-Puch introduced the well-known 8000 series in 1976, the Plus series formed the core programme of the Austrian tractor maker from St. Valentin through the 1960s and 1970s.

The register lists 17 live models, from the 430 to the 1400 a, built between 1967 and 1981. Output ranges from 23.6 to 103 kW, weight from 1,770 to 5,660 kg, displacement from 1,992 to 6,592 cm3, across two-, three-, four- and six-cylinder engines.
The series already covered a very broad power spectrum, from a compact two-cylinder yard tractor to the large six-cylinder 1400 a model for arable work.
As a direct forerunner of the 8000 generation, the Plus series laid the technical groundwork for the rugged, low-maintenance design Steyr tractors remain known for today.
Unlike modern tractors, Plus-series machines are not subject to any emissions stage – they were built before EU emissions standards for farm machinery existed, so they need neither a particulate filter nor an AdBlue system, which significantly simplifies servicing and repair under the bonnet. In return, they do entirely without the electronic engine management of later series; the injection pump and governor are purely mechanical, which makes repair easier for specialist diesel workshops but rules out fault diagnosis via computer.

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.
