Deutz D Series – Air-Cooled Compact Tractors of the Early 1960s, 10.2 to 38.1 kW and Operating Weight from 920 to 2,270 kg
The D series covered Deutz's compact tractors of the early 1960s, powered by the brand's characteristic air-cooled diesel engines. According to the register, output of the recorded models ranges from 10.2 to 38.1 kW, with models rated in horsepower spanning 15 to 52 hp, using one- to four-cylinder engines with displacement from 850 to 3,400 cm³.

Recorded operating weight runs from 920 to 2,270 kg, wheelbase from 1,690 to 2,230 mm, and top speed of the listed models spans 17.7 to 30 km/h. Models such as the D 30 S-Plantage show that narrow-track variants for specialty crops were also offered within the series.
The air-cooled engines were considered robust and low-maintenance, since they needed no coolant or the wear parts that go with it. When buying a used D-series tractor, the engine variant matters most, as cylinder count and displacement differ considerably within the range.
The D series was built from 1959 to 1964, predating the international standardisation of the three-point hitch under ISO 730 in 1977, and in part even predating the power take-off speed of 540 revolutions per minute internationally fixed in 1965 under ISO R 500. Deutz still exists as an engine manufacturer today and continues to supply spare parts for its classic air-cooled units, easing the upkeep of these compact tractors.
