Hürlimann D Series – Swiss Diesel Tractors From the 1940s to the 1970s: two- to six-cylinder engines with 20.6 to 106.6 kW (28 to 145 hp), 2,360 to 9,186 cm³ displacement
The D designation covered the diesel tractors built by the Swiss manufacturer Hürlimann in Wil from the late 1940s to the mid-1970s – from the D-400 (production starting 1946) through the D-100 and D-200 families to the D-550 Hydrostat of 1974. That long span explains the wide range of register data: output from 20.6 to 106.6 kW, models rated in horsepower from 28 to 145 hp, and cylinder counts from two to six.

Recorded operating weight runs from 1,480 to 6,350 kg, displacement from 2,360 to 9,186 cm³, and wheelbase from 1,636 to 3,000 mm. Top speed of the listed models spans 20 to 45 km/h, reflecting the long technical development from early post-war designs to later Synchromatic gearboxes.
Hürlimann was an independent Swiss builder before the company became part of the Italian SAME group. For collectors and buyers of historic D-series tractors, the exact model designation matters most, since engine, gearbox and drive type vary considerably within the series.
Across the three decades of this series, mounting technology also changed: early D models used a category I three-point hitch, the more powerful later types already category II under ISO 730, and the PTO moved from the single-speed 540 standard to a two-speed version with 540 and 1,000 rpm. Parts for early D models are today mainly available through specialist Hürlimann and SAME dealers.

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.
