The register lists 3 versions here with 25.8 to 30.9 kW from three- and four-cylinder diesel engines of 1,490 to 1,566 cc at a constant 3,000 rpm, kerb weights of 1,110 to 1,240 kg, lengths of 2,690 to 3,030 mm, widths of 1,020 to 1,260 mm and heights of 2,000 to 2,030 mm.

With its compact build and standard four-wheel drive, the Prince series positioned itself in the segment of small all-rounders for special crops, fruit growing and viticulture and municipal work, where manoeuvrability and traction mattered more than raw engine power.

When buying a used Prince model, the key points are the condition of the engine and injection pump, wear on the four-wheel-drive system and front-axle gearing, and tightness of the hydraulics, plus corrosion on cab and chassis; spare parts for the Prince series are available through the SDF group's parts channels.

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.
