Model historyEdit

For Company history, see International Harvester.

In late 1970 the 170 net hp International TD-20C replaced the 160-hp TD-20B. A 573 ci turbocharged V8 diesel replaced the previous 429 ci turbo-six. Despite the power increase, the TD-20C was down on power compared with the 180-hp Caterpillar D-7F and 195-hp Allis-Chalmers HD-16 Series B. In 1973 International boosted the power of the TD-20C to 190 net hp.
