The International 544 Hydro was a hydrostatic drive utility tractor built by International Harvester from 1968 to 1973 in the USA.

Model historyEdit

Main article: International Harvester

For gear drive version see: International 544. For industrial model see: International 2544 Hydro. For row crop model see: Farmall 544 Hydro.

The International 544 Hydro was the same as the 544 gear drive model 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

The gasoline-powered International 544 Hydro had little direct competition. The Case 730CK Special Case-o-matic was a larger, taller, standard tractor with a more powerful engine and the Case-o-matic 8-speed manual transmission with torque converter. Ford offered the Select-O-Speed 10-speed power shift transmission in its tractors. In 1968 the 4000 All Purpose was less powerful than the International and the 5000 was more powerful. In 1969 the 4000 got a bigger engine, bringing it closer to the power of the International.

Tractor Comparison, tractors with diesel engines and automated transmissions (hydrostatic, power shift, or torque converter)Edit

The diesel-powered International 544 Hydro had little direct competition. The Case 730CK Special Case-o-matic had about the same power but in a taller, heavier standard tractor. In 1968 the Ford 5000 All Purpose Select-O-Speed had about the same power and weight but in 1969 it got a larger engine and moved into a different power class. The smaller Ford 4000 All Purpose also got more power but it still wasn't a match for the International.
