The T-340 series was a series of compact crawler tractors built by the International Harvester company from 1959 to 1965 in the USA.

Model historyEdit

For Company history, see International Harvester.

International entered the compact crawler market, dominated for many years by John Deere and Cletrac/Oliver, with the International T-340, essentially a tracked version of the 340 Utility wheel tractor. A 135 ci 4-cylinder gasoline engine also powered the T-340. The standard transmission was a 5-speed, with either the Torque Amplifier 2-speed planetary reduction gear or the Fast Reverser forward-reverse gear set optional. When it was new in 1959, the T-340 was at the top of the compact class for hp, followed by the Case 310 Crawler, John Deere 430C and 440IC, and Oliver OC-6. The 1960 Allis-Chalmers H-3 and John Deere 1010C nearly equaled the International.

In 1961 International added the TD-340 diesel version, fitted with the same 166ci 4-cylinder engine as the 340 Diesel wheel tractor. The TD-340 competed with several other compact diesel crawlers already on the market: the Allis-Chalmers HD-3, Case 310E, Fiat 411C, and John Deere 1010C. The Oliver OC-4-3D was smaller and less powerful.

International T-340A 1962

International T-340 Series A 1962

The T-340 series was upgraded for 1962 and designated the Series A. The main mechanical change was the use of a standard 5-roller track frame, with the original 4-roller version optional. Also the original 2-tone red and white color scheme was changed to a solid color, usually yellow for tractors destined for industrial use and red for agricultural tractors. In 1967 the T-340 series was replaced by the 500 series.
