The Hydro 1066, initially called 1066 Hydro, had a hydrostatic drive, but it was later renamed Hydro 100 due to confusion about its drawbar horsepower. The hydrostatic drive needed a lot of power to operate, and the 1066 Hydro had less power than the gear-driven 1066. In 1973, changes were made to increase its horsepower.
The International Harvester 1066 Row-Crop Tractor had an engine called the International Harvester DT414 turbocharged diesel 6-cylinder liquid-cooled engine, which delivered 108 horsepower at 2400 rpm.
