David Brown 770 Selematic (1965-1970) from Meltham, Yorkshire: low-built three-cylinder diesel of 2,394 cc, 33.5 hp/24.6 kW at 2,000 rpm, only 1,219 mm high, weight 1,464 kg
David Brown was a British tractor manufacturer based in Meltham, near Huddersfield in Yorkshire. The 770 Selematic was built from January 1965 to 1970. Unlike the four-cylinder models in the range, it carries a compact three-cylinder engine, which placed it in a smaller power class among the models then on offer.

The three-cylinder diesel engine with water circulation cooling has a displacement of 2,394 cc and produces 24.6 kW (33.5 hp) at 2,000 rpm, with 137 Nm of torque. Notable is its height of only 1,219 mm, with a length of 2,858 mm, a width of 1,641 mm and a wheelbase of 1,905 mm; it weighs 1,464 kg. Its top speed is 25 km/h.
A height of around 1.2 metres is unusually low for an agricultural tractor and points to a design for work under low-growing crops, in glasshouses or in orchards, where a tall standard tractor would not fit. The three-cylinder engine of nearly 2.4 litres provided enough pulling power for this at a low kerb weight and with good manoeuvrability.
When buying a used example of such a low-built tractor, besides the clutch, gearbox and hydraulic tightness, check in particular the condition of the water circulation cooling, which works without a separate pump and depends on an adequate coolant level, as well as the steering head and front axle bearings, which are under greater load in this low, compact design. Parts for the engine and chassis are supplied by specialist dealers in classic David Brown tractors.
