The D 1666 from Lanz is part of the Volldiesel series. Production: 4/1955–12/1955. The engine delivers 16 hp (11.7 kW), has 2 cylinders, with a displacement of 1,250 cm³. Rated speed is 2,000 rpm. The machine is 2,510 mm long, 1,630 mm wide and 1,475 mm high. The unladen weight is 1,050 kg. The wheelbase measures 1,650 mm. Ground clearance is 440 mm. Top speed is 19.62 km/h. Transmission: 6/1-manual gearbox. The engine is water-cooled. Tyres: front 4.00-15, rear 7-24. The fuel is diesel. Construction: frameless unit construction. The gearbox offers 6 forward gears. Around 596 units were built. The Volldiesel series covers 10 models. Rated output within it ranges from 11 to 40 hp; the D 1666 sits in the lower part of that range with 16 hp. Its immediate neighbours are the D 1306 below it with 13 hp and the D 2402 above it with 24 hp. Unladen weight within it ranges from 770 to 2,650 kg; here the D 1666 sits at the bottom of that range with 1,050 kg. 28 Lanz models across 10 series are on record.

Lanz Volldiesel (1955–1960) – the last Bulldogs: D 1106 to D 4016, the first digits as hp, one- and two-cylinder two-strokes with full diesel injection, the end of Mannheim under John Deere, 8 to 29 kW

Volldiesel is Lanz's name for the last Bulldog generation: from 1955 Mannheim replaced the medium-pressure Halbdiesel with full diesel injection – the engine remained the horizontal one- or two-cylinder two-stroke but started without preheating like any modern diesel. In 1956 John Deere took over Heinrich Lanz AG, and the Volldiesels ran until 1960 as the last tractors on the Bulldog principle before Deere switched Mannheim to multi-cylinder four-strokes. The type logic: the four-digit number gives the output in hp in its first two digits – D 1106 about 11 hp, D 1616 16 hp, D 2416 24 hp, D 2816 28 hp, D 4016 40 hp – and the version in the last two: 06 for plain equipment, 16 for the version with more gears and equipment, 02 and 12 for intermediate levels. The D 1106 to D 1666 are the single-cylinders, D 2402 to D 4016 the twins – the D 4016 with 4.2 litres from two cylinders at only 1,000 rpm the largest.

The register lists 10 versions with 8.1 to 29.3 kW (12 to 40 hp), 533 to 4,222 cm³ with one or two cylinders, rated speeds around 1,000 to 1,050 rpm, unladen weights from 770 to 2,650 kg, lengths from 2,440 to 3,380 mm, widths from 1,000 to 1,805 mm and heights from 1,385 to 1,930 mm – all diesel.

The Volldiesels are the full stop of a design that began in 1921: the slow-running big cylinder that burned any fuel and shaped the country roads with its beat – the D 1616 and D 2416 were the best-selling small Bulldogs and are today the brand's most accessible collector pieces.

On used tractors, the piston and cylinder of the two-stroke, a leak-free crankcase, injection pump, gearbox and originality count; the club scene and remanufacturers secure the parts.

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.
