Case IH HYDRO-86 Tractor Parts
The Case IH Hydro 86 was a popular tractor manufactured from 1981 to 1984, known for its smooth hydrostatic transmission. Powered by a reliable 82 HP diesel engine, it delivered approximately 68 PTO horsepower. Farmers appreciated its ease of use and versatility in various agricultural tasks, making it a valuable asset for row crop and livestock operations.
The Case IH Hydro 86, produced between 1981 and 1984, was part of the 86 series, known for their advancements in operator comfort and efficiency. It featured an International Harvester (IH) D-358 5.9L 6-cylinder diesel engine, producing approximately 82 engine horsepower. This engine's displacement ensured ample power for a variety of tasks. A key feature was its hydrostatic transmission, offering infinite speed control and ease of operation, a departure from traditional gear-driven tractors. The Hydro 86 provided approximately 68 PTO horsepower, available in the standard 540 RPM configuration. Its hydraulic system delivered around 15 GPM of flow, with typically two remote valves for implements. The 3-point hitch was a Category II, offering a lift capacity of around 4,700 lbs. Common applications included row crop work like planting and cultivating, hay baling and moving, livestock feeding and manure handling, and light tillage. Compared to gear-driven 86 series tractors, the Hydro 86 offered superior ease of use, especially for tasks requiring frequent speed changes or precise control. However, it sometimes lacked the raw pulling power of its gear-driven counterparts in very heavy tillage applications.

Maintenance Tips
- Engine Oil & Filter: Change the engine oil and filter every 250 hours of operation using a high-quality diesel engine oil that meets API CH-4 or better specifications.
- Hydraulic System Maintenance: Check the hydraulic fluid level regularly and change the hydraulic filters every 500 hours of operation. Use only fluids meeting Case IH specifications to prevent damage to the hydrostatic transmission.
- Fuel System Care: Use clean, high-quality diesel fuel and replace the fuel filters every 250 hours to prevent fuel system problems. Consider using a fuel additive to prevent gelling in cold weather.
- Seasonal Storage: Before storing the tractor for the off-season, completely fill the fuel tank to prevent condensation. Change the engine oil and filter, grease all fittings, and disconnect the battery. Store the tractor in a dry location to prevent rust and corrosion.
