Hanomag K – Heavy Tractor Series, 1933 to 1964: two- to six-cylinder diesels with 37 to 66 kW (50 to 90 hp), 3,715 to 9,348 cm³ displacement, water-cooled
The K series covered Hanomag's heavier tractor models across an unusually long production run from 1933 to 1964. According to the register, output of the recorded models ranges from 37 to 66 kW, with models rated in horsepower from 50 to 90 hp, using two- to six-cylinder engines with displacement from 3,715 to 9,348 cm³.

Recorded operating weight runs from 4,510 to 8,700 kg, and top speed of the listed models spans 6 to 9.7 km/h – typical for heavy field tractors of the era without gearing designed for road travel.
Models such as the K90/E, with over 9,000 cm³ of displacement, ranked among the largest tractors of their time in Germany. For a used K model, the exact type designation matters most given the long production span, as pre-war and post-war designs are fundamentally different technically.
The entire production run of the K series, from 1933 to 1964, lay well before the introduction of the first European emissions stages in 1999, so all models ran without any emissions certification. With output up to 66 kW, the most powerful K models already reached the boundary of three-point category II under ISO 730, though many historic implements of that period were not yet built to this standard. Original parts for the K series are likewise scarce today and mainly sourced through specialist vintage-machinery dealers, since Hanomag tractor production has not existed since 1971.

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.
