Lamborghini Vierte R-Baureihe
5 models in this series
Lamborghini R-503 to R-904 DT – the small and mid-sized R range from Pieve di Cento: DT for four-wheel drive, three- and four-cylinders of 2.8 to 5.0 litres, 35 to 68 kW, with markedly different heights across versions
Alongside the big six-cylinder R group, Lamborghini Trattori's R range also comprises a smaller and mid-sized line with three- and four-cylinder engines, including the R-503, R-603, R-704, R-804 and R-904. The type logic follows the same pattern as the large R models: the three-digit number grows with engine size and power class, and DT stands for "Doppia Trazione", the four-wheel drive on every model in the register. What stands out is the comparatively wide spread in overall height, from 1,490 to 2,210 mm, pointing to different cab and platform versions within the same range, while the engines are consistently three- or four-cylinder diesels from the SAME Deutz-Fahr modular kit.

The register lists 5 versions with engines of 2,827 to 4,986 cm³, 3 to 4 cylinders, outputs of 34.7 to 67.7 kW, operating weights of 1,740 to 3,010 kg and lengths of 3,210 to 3,530 mm at 2,000 to 2,300 rpm.
These R models served the mid-market segment for small and medium-sized farms, below the big six-cylinder R range and the same maker's Premium range.
On used tractors, the condition of clutch and gearbox, leak-free hydraulics, the condition of four-wheel-drive hubs and rust on wings and cab count; parts supply runs through the SAME Deutz-Fahr dealer network.
