Irus U – single-axle mini-tractors from Burladingen: types U 600 to U 1402, single-cylinder engines of around 250 cm³, unladen weights of 190 to 250 kg, diesel or petrol drive

Irus, a manufacturer based in Burladingen on the Swabian Jura, built a range of single-axle mini-tractors under the U designation, widespread in the post-war period for tilling small plots and in direct-marketing operations. The types U 600, U900, U 1200/K and U 1402 recorded in the register differ mainly in the engine offered, which depending on the version ran on diesel or petrol, or the corresponding mixture-fuelled drive.

The register lists 4 versions with single-cylinder engines of around 250 cm³ displacement, unladen weights from 190 to 250 kg and a rated speed of 3,000 rpm throughout.

Single-axle mini-tractors such as the Irus U range served smaller and part-time farms, market gardens and vineyards as a lightweight, manoeuvrable power source for tilling and pulling transport trailers, in a market segment served in southern Germany by numerous smaller manufacturers.

On a used Irus U-range implement, the condition of the single-cylinder engine including the carburettor or injection system, wear on the clutch and drive belt, and the function of the steering handles all count; parts for these early single-axle implements are practically only available through collectors and specialist secondhand-parts exchanges.

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.
