Model History Edit

For Company history see
Main article: International Harvester Co article

The Titan 12-25 4-cylinder tractor was introduced in 1914. It was smaller than the previous Titan Type D and powered by an L-head 4-cylinder engine. In 1917 it was revised with a more powerful overhead-valve engine and became the Titan 15-30. In 1917 antitrust action against International Harvester forced the company to do away with separate McCormick and Deering dealers selling separate Mogul and Titan tractors. In 1918 the name of the Titan 15-30 was changed to International 15-30

Preservation Edit

Little information on any of these tractors in preservation is currently available here.

  • One example was seen at Carrington Steam and Tractor Rally 2015 but serial number was not clear on photo taken of it to read. The tractor was in 'Unrestored finish' i.e no paint just a weathered rust patina. It was not seen running by the editor but looked as if it had run recently.
Do you know of any other examples to list ?
