Case IH 1086 Tractor Parts
1086 parts and accessories
The Case IH 1086 tractor, manufactured from 1976 to 1981, was a popular workhorse on farms across North America. Powered by a robust International Harvester DT-414 diesel engine producing around 131 horsepower, this tractor offered ample power for a variety of tasks. With a PTO horsepower of approximately 110, the 1086 was well-suited for powering implements and quickly became a favorite for its reliability and versatility.
The Case IH 1086 was introduced in 1976 as part of the '86 series, replacing earlier International Harvester models. Production continued until 1981, establishing it as a key player in the mid-sized tractor market. The heart of the 1086 is the International Harvester DT-414, a 414 cubic inch (6.8 L) turbocharged inline 6-cylinder diesel engine, generating approximately 131 engine horsepower. It features a robust gear-drive transmission, offering options like a standard 8-speed with TA, or optional partial powershift transmissions that provided more gear selections. The PTO delivers around 110 horsepower, typically at 540 RPM. The hydraulic system boasts a capacity of approximately 25 GPM, with two to three remote valves for implement control. The 3-point hitch is a Category II, offering a lift capacity of around 6,400 lbs. Commonly used for row crop operations, hay baling, livestock feeding, and light tillage, the 1086 distinguished itself from smaller models in the IH lineup with its increased power and hydraulic capacity. It offered a balanced combination of power and maneuverability, making it suitable for a wide range of farming applications.
