Laffly TD.10 (Pozostałe modele) – air-cooled single-cylinder diesel producing 14 hp at 1,850 rpm from 765 cc, with a kerb weight of 780 kg, a compact tractor from the French manufacturer Laffly
Laffly was a French vehicle manufacturer best known for lorries, road-building machinery and military vehicles. Agricultural tractors made up only a small part of the Laffly range; the TD.10 belongs to the class of simple, light tractors that small farms, market gardens and municipalities used at the time for mounted implements and light draught work.

The TD.10 is powered by an air-cooled single-cylinder diesel engine of 765 cc, producing 14 hp (10.2 kW) at 1,850 rpm. With a kerb weight of 780 kg, a length of 2,620 mm, a width of 1,650 mm and a height of 1,575 mm on a 1,420 mm wheelbase, it counts among the smallest tractors of its era; top speed is 15 km/h.
A single cylinder of this size delivers even torque at low speed and suits simple draught work, small tillage implements and transport around the yard, rather than heavy ploughing over large areas. Air cooling makes the engine tolerant of frost and water shortage, but demands clean cooling fins and an intact fan drive so heat is reliably carried away.
When buying a used example of such a small single-cylinder diesel, the condition of piston and cylinder matters most, as even modest wear noticeably cuts the limited power. Checking the oil level, the cooling fins and the fan mounting is as important as checking the steering and brakes. Parts for engine and chassis are scarce given the small numbers built, and usually only available through specialist collectors or replica manufacture.
