Case IH 784 Tractor Parts

784 parts and accessories

The Case IH 784 tractor, manufactured from 1978 to 1984, was a versatile workhorse for farmers. Powered by a robust 55-horsepower diesel engine, and boasting around 50 PTO horsepower, it provided ample power for a variety of tasks. Its reliability and straightforward design made it a popular choice for farmers needing a dependable utility tractor.

The Case IH 784 was part of the International Harvester/Case IH line of tractors produced from 1978 to 1984. It succeeded earlier models, incorporating improvements in engine technology and operator comfort. The 784 was equipped with an International Harvester D-239 diesel engine, a 239 cubic inch (3.9L) 4-cylinder engine producing approximately 55 horsepower. The transmission was typically a gear-drive, offering 8 forward and 4 reverse speeds, providing suitable speed ranges for various farm operations. PTO horsepower was around 50 HP, available at the standard 540 RPM. Hydraulic capacity was adequate for operating implements, with a typical flow rate around 8-10 GPM and often featuring one or two remote valves. The 3-point hitch was Category II, capable of lifting around 3300 lbs. Common applications included row crop work, haying, livestock operations (feeding, manure handling), and light tillage. What set the 784 apart was its simple design and its ability to perform well in a wide range of farming activities, making it a very versatile tractor for its time. It was smaller and more maneuverable than the larger Case IH models like the 986, but offered more power and capabilities than the compact 584.
