Lanz HR 7 series – the D 8516: a water-cooled single-cylinder diesel producing 25.6 kW, its rated speed raised to 599 rpm from April 1950, and a 3,780 kg weight
Lanz, in full Heinrich Lanz AG, was based in Mannheim. Unlike the related, multi-fuel D 8506 from the same model family, the D 8516 of the HR 7 series runs on pure diesel fuel and is genuinely water-cooled with a pump rather than relying only on thermosyphon action, two technical differences within the same model family.

The D 8516 produces 25.6 kW, or 35 hp, at a rated speed given in the register as 540 rpm, raised to 599 rpm from April 1950. The machine weighs 3,780 kg, reaches 18 km/h, and measures 3,400 mm in length, 1,780 mm in width and 2,185 mm in height.
Raising the rated speed during an ongoing production run is a documented technical change of the kind seen on long-lived series of this period, without any change to displacement or cylinder count. Genuine water cooling with a pump, compared with the purely thermosyphon cooling of related models, allows more even cooling under the higher continuous load that a raised rated speed brings with it.
When buying a used D 8516, it is worth first establishing whether the fitted engine carries the original rated speed of 540 rpm or the 599 rpm that applied from April 1950, since the two versions may need different fuel-supply parts. The water cooling calls for a check of corrosion and pump tightness, alongside the usual look at the flywheel and clutch after decades of use.

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.
