Model historyEdit

For Company history, see International Harvester.

For gear drive version see: International TD-25 Series 250

The International TD-25 Series 250TC was identical to the gear drive TD-25 Series 250, except that the 4-speed syncromesh main transmission was replaced with a 2-speed constant mesh and torque converter. Combined with the "Planet Power Steering" 2-speed power shift tracks this gave 4-speeds forward and reverse. The 230 hp (170 kW) net 4-speed TD-25TC competed with the 225 hp (168 kW), 2-speed plus torque converter, Allis-Chalmers HD-21 and the 235 hp (175 kW), 3-speed power shift and torque converter, Caterpillar D8H.
