© Science Museum / Science & Society Picture Library
Titan' 10/20 hp agricultural tractor with a two-cylinder horizontally opposed gasoline (petrol)/kerosene engine, manufactured by the International Harvester Corporation (IHC), Chicago, Illinois. Introduced in 1915 and in full production by 1916, this tractor was the last of International Harvester's heavyweight designs. It was made in far greater quantities than any other IHC tractor before it, and had a better power to weight performance than IHC's other models of the time. It was very reliable, and was imported into Britain in larger numbers than its contemporaries to be used in the Ministry of Food Production's efforts to feed First World War Britain.
