International Harvester 666

The International Harvester 666 is a utility tractor built from 1972 to 1976. It's a 2-wheel drive machine with a powerful 6-cylinder diesel engine. The engine is big for its class, with 312 cubic inches of displacement. It runs at 2000 rpm, which is slower than most tractors but helps save fuel.

This tractor weighs 7053 pounds, making it heavier than many similar models. It has a sliding gear transmission with 5 forward speeds and 1 reverse. The 666 comes with hydrostatic power steering for easy handling and dry disc brakes for good stopping power. It has a rear PTO that spins at 540 rpm, which is great for running farm tools. The tractor uses the IH Fast Hitch system and has a Category II hitch at the back. Farmers can choose between an open cab or a two-post ROPS for safety.
