Case IH 856 Tractor Parts
856 parts and accessories
The Case IH 856 tractor, manufactured from 1977 to 1983, was a popular choice for farmers needing a reliable workhorse. Powered by a 76 horsepower diesel engine, the 856 delivered ample power for various field tasks. Its practical design and strong PTO horsepower made it well-suited for hay baling, tillage, and general farm work, solidifying its place in agricultural history.
The Case IH 856 tractor was produced from 1977 to 1983, building upon the legacy of International Harvester's reliable designs before the Case IH merger. It featured an International Harvester D-358 6-cylinder diesel engine, delivering approximately 76 horsepower. The engine's displacement was around 358 cubic inches. The 856 utilized a gear-type transmission, typically with 8 forward and 4 reverse speeds, providing a range of options for different field conditions. The PTO horsepower was rated at approximately 67 HP with a 540 RPM PTO speed. The hydraulic system offered around 14.5 GPM, powering implements and steering with adequate flow. The 3-point hitch was a Category II, capable of lifting around 4,000 lbs. Farmers commonly used the 856 for a variety of tasks including row crop cultivation, hay production (mowing, baling), livestock feeding operations, and light tillage work. The 856 distinguished itself from smaller models with its increased power and hydraulic capacity, while remaining more affordable than larger, more complex tractors in the Case IH lineup, making it a versatile and cost-effective option for medium-sized farms.
