The International TD-20 Series 201 was a diesel engined crawler tractor built by the International Harvester company from 1961 to 1962 in the USA.

Model historyEdit

For Company history, see International Harvester.

The TD-20 Series 201 replaced the Series 200. The main change was the addition of a turbocharger to the 691 ci 6-cylinder engine to slightly increase the power output, from 134 to 140 net engine hp. This brought the TD-20 up equal with the Caterpillar D-7D in power and closer to the class-leading Allis-Chalmers HD-16. However, in 1962 Caterpillar jumped ahead with the 160-hp Caterpillar D-7E. International had apparently wrung all the power possible out of the 1938-vintage D-691 engine so, in 1963, brought out the all-new TD-20B with a brand-new high-speed turbocharged diesel.
