Deutz D 6807 (C): air-cooled tractor from the 07 series built 1981 to 1982 with a 3.8-litre four-cylinder engine, 49 kW and a 25 km/h top speed
The 07 series comprised air-cooled Deutz tractors from the early 1980s; the D 6807 (C) was built from 1981 to 1982. The type designation followed the naming logic usual at Deutz, where the number roughly matches the engine's output in hp.

The air-cooled four-cylinder diesel engine with 3,768 cm³ of displacement produces 67 hp, or 49 kW, at 2,300 rpm, with 238 Nm of torque. At 2,860 kg, 3,760 mm long, 2,560 mm high, 1,990 mm wide and with a 2,170 mm wheelbase, top speed is limited to 25 km/h.
With 49 kW and a chassis limited to 25 km/h, the D 6807 (C) was a pure field-and-yard tractor for tilling small to medium fields with a plough or cultivator and for transport work with a trailer or forage wagon around the farm, rather than for brisk road travel. At 238 Nm at 2,300 rpm, torque was only slightly below that of the more powerful D 7007 and was enough for the usual power-take-off work at the 540 rpm standard.
When buying a used air-cooled Deutz four-cylinder from these years, the condition of the cooling fan and cylinder fins matters, along with oil consumption at high hours. Also worth checking are the clutch, gearbox and brakes, as well as corrosion on the frame and sheet-metal parts, which can be well advanced on machines of this age. The valve-cover gaskets and the mounting of the cooling fan are worth adding to the list too, since faults there cause follow-on damage faster on an air-cooled engine with no water circuit.
