Case IH 785 Tractor Parts
785 parts and accessories
The Case IH 785 tractor, manufactured from 1985 to 1990, was a versatile workhorse powered by a reliable diesel engine producing around 76 horsepower. Known for its robust build and user-friendly operation, the 785 offered a PTO horsepower rating suitable for a variety of implements, making it a popular choice for mixed farming operations.
The Case IH 785 was introduced in 1985 as part of the Case IH 85 series, replacing earlier International Harvester models. Production continued until 1990. It was designed to be a reliable and versatile tractor suitable for a wide range of farming tasks. The 785 is powered by an International Harvester D-239 diesel engine, a 239 cubic inch (3.9L) 4-cylinder engine, producing approximately 76 horsepower. The tractor features a mechanical transmission with multiple speed options. These typically included a synchronized gear transmission with several forward and reverse speeds, allowing for precise speed control in the field. The PTO delivers around 68 horsepower at 540 RPM. The hydraulic system provides around 11.5 GPM flow, sufficient for operating various implements, with available remotes. It has a Category II 3-point hitch. The 785 found applications in row crop farming, hay production, livestock operations, and light tillage. It distinguished itself with its balanced power, simple mechanics, and dependability compared to larger or more complex models within the Case IH lineup.
