The International TD-25B replaced the TD-25 Series 250. The new model was about one ton heavier but used the same engine and transmission as the previous version. In 1965 the governed engine speed was increased from 1500 to 1600 rpm, with no change in rated power. The 230 net hp 8-speed TD-25B originally competed with the 235-hp 6-speed Caterpillar D-8H. In 1966 Caterpillar increased the power of the D-8H to 270 net hp and moved it out of the International's class. International kept the TD-25B in production until 1972.
