Overview

The International Harvester 1066 is a robust row-crop tractor produced by International Harvester from 1971 to 1976. It was available with several drive configurations: standard 2WD or an optional 4WD version, catering to various farming needs. The powertrain consisted of multiple options including a gear-drive transmission with 8 forward and 4 reverse speeds, a two-speed power shift transmission offering 16 forward and 8 reverse speeds, and an infinite two-range hydrostatic transmission offering exceptional control over speed and torque.

The liquid-cooled engine ensures reliable operation across various conditions while the turbocharge feature provides a boost in engine performance. Standard features for the 1066 model included hydrostatic power steering and self-adjusting double dry disc brakes, enhancing the operator's control and safety.
