The Case IH 685 was introduced in 1981 as part of the International Harvester lineup, later transitioning to the Case IH brand during the merger. Production ran until 1984. The heart of the 685 is an International Harvester D-239 diesel engine, a 239 cubic inch (3.9L) displacement, producing approximately 68 engine horsepower. The PTO horsepower is rated around 60 HP. The standard transmission was a gear-type transmission, typically offering 8 forward and 4 reverse speeds, though some models offered a creeper gear option for specialized applications. The open-center hydraulic system delivers around 12 GPM, powering two rear remotes. It features a Category II 3-point hitch with a lift capacity of approximately 3,500 lbs. Farmers commonly used the 685 for tasks like hay baling, mowing, light tillage, and livestock feeding. It distinguished itself with its robust construction and reliable engine, offering a balance of power and maneuverability, making it a solid all-around utility tractor.
