International Harvester Titan 10-20.
The I.H. Titan was produced from 1916 to 1922, during which time 78,363 Titans were produced. The Titan 10-20 was the most versatile International tractor of its time. Production peaked in 1920 with 21,503 Titans built that year. This tractor used an International two-cylinder engine with a 6 1/2" x 8" bore and stroke with parallel cranks. This engine used a thermosyphon cooling system by means of a water tank, which eliminated the need of a fan or water pump. Two forward speeds were also used. Rated at 10 drawbar and twenty belt horsepower, the tractor actually produces a maximum 13.67 drawbar and 28.15 brake horsepower. The engine in front of it is an International Harvester Model M. Owned by Dean Alling.
