The International 2544 Hydro was an industrial tractor built by International Harvester from 1968 to 1973 in the USA.

Model history[edit | edit source]

Main article: International Harvester

For gear drive version see: International 2544 Hydro. For regular utility model see: International 544.

The International 2544 Hydro was the same as the gear drive International 2544 except for its 2-range hydrostatic transmission and increased engine speed of 2400 rpm (to increase engine power and compensate for losses in the hydrostatic pump and drive unit.

Tractor Comparison, tractors with gasoline engines and automated transmissions (hydrostatic, power shift, or torque converter)[edit | edit source]

The Massey Ferguson MF30 and White 2-62, both with torque converter drive, were the closest competitors for the hydrostatic drive International 2544 Hydro, in both gasoline and diesel versions. The similar-sized Ford 4400, with its Select-O-Speed power shift transmission, was considerably less powerful in 1968 but a larger engine in 1969 brought it closer to the International.

As with the gasoline-powered version, the diesel International 2544 competed directly with the John Deere JD400 and JD401, Massey Fergusom MF30 (and earlier MF3165), and the improved Ford 4400 introduced in 1969. The diesel-powered Oliver 770 Industrial also had about the same power as the International. The 1968 Ford 4400 and the nearest models from Allis-Chalmers and Minneapolis-Moline had less power than the International.
