The engine is an air-cooled two-cylinder diesel of 1,261 cc, producing 9 kW (12.2 hp) at 1,500 rpm. The 2 D is 2,985 mm long, 1,695 mm wide and 1,397 mm high, with a wheelbase of 1,829 mm and a weight of only 991 kg. Its top speed is 15 km/h.
At just under 9 kW and under a tonne in weight, the 2 D sits in the lightest class of agricultural tractors, sufficient for smaller plots, grassland and implements with low power demand. Air cooling was the exception for this maker, since David Brown mostly used water-cooled engines; it does away with a radiator, water pump and coolant, but requires a clean cooling fan and unobstructed cooling fins so the engine does not overheat.
When buying a used air-cooled two-cylinder, first check the cylinder block's cooling fins and the fan for dirt and damage, since either can cause engine damage through overheating. Beyond that, check the clutch and gearbox, tightness of the injection pump, the state of the hydraulics and rust on the light sheet-metal bodywork. Parts for this small David Brown diesel are supplied by specialist dealers in classic tractors.
