The Lamborghini R-1056 (DT) is a machine built by Lamborghini. Production: 1977–1984. The engine delivers 105 hp (77.2 kW), has 6 cylinders, with a displacement of 5,431 cm³. Torque is 340 Nm. Rated speed is 2,220 rpm. The machine is 4,520 mm long, 2,250 mm wide and 2,900 mm high. The unladen weight is 3,930 kg. The wheelbase measures 2,725 mm. Ground clearance is 540 mm. Top speed is 25 km/h. Transmission: 12 V/3 R. The engine is air-cooled. Tyres: front 9.50-20 ASF (DT: 13.6-28 AS), rear 18.4-38 AS. The fuel is diesel. The bore measures 98 mm. The stroke is 120 mm. The compression ratio is 17.5:1. Maximum torque is reached at 1,445 rpm. Construction: unit construction (no separate frame). Rated output across the Lamborghini range ranges from 15 to 269 hp; the R-1056 (DT) sits in the lower part of that range with 105 hp.

Lamborghini Trattori – other models: Italian tractors outside the named ranges, from Green Pro to Racing and R6.150, 16.2 to 158 kW, part of SDF/SAME since 1972

This page gathers Lamborghini tractors outside the named ranges, from the compact Green Pro and Spire models through the R and Racing series to the large R6.150 and R4.110. Ferruccio Lamborghini founded the company in 1948 near Bologna, before launching the sports car maker of the same name in 1963; the tractor division passed to the SAME group (today SDF) in 1972, which still runs Lamborghini Trattori as a standalone brand with its characteristic yellow paintwork. The model names draw on motorsport terms such as Racing, Formula, Champion, Strike, Sprint, Spark and Crono.

The register lists 45 versions here with 16.2 to 158 kW from two- to six-cylinder engines of 1,318 to 8,710 cm³, unladen weights of 1,000 to 6,710 kg, gross vehicle weights of 2,500 to 10,000 kg, lengths of 2,270 to 4,750 mm, widths of 1,330 to 2,600 mm, heights of 1,100 to 2,900 mm, torque of 206 to 353 Nm and rated speeds of 1,900 to 2,200 rpm.

As part of the SDF group, Lamborghini shares engine and transmission technology with sister brands Same and Deutz-Fahr, but positions itself with distinctive design and colour as the more emotive alternative in the same market segment, from the compact orchard tractor to the large field tractor for southern and eastern European markets.

When buying used, the smaller Green Pro and Spire models call for checking the hydrostatic drive and front-loader mounting, the larger R and Racing series the turbocharger, injection pump and clutch, and generally rust on wings and the condition of cab seals; since engines come partly from Lamborghini itself and partly from Mitsubishi, Perkins and Deutz, parts supply differs by engine supplier.

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.
