Case IH HYDRO-84 Tractor Parts

Hydro 84 parts and accessories

The Case IH Hydro 84, manufactured from 1981 to 1984, was a popular choice for farmers seeking a versatile and reliable tractor. Powered by a 52 horsepower diesel engine and boasting a PTO horsepower of 45, the Hydro 84 provided ample power for various agricultural tasks. Its hydrostatic transmission made it particularly well-suited for operations requiring precise speed control, further cementing its place as a trusted workhorse on farms across the country.

The Case IH Hydro 84 was introduced in 1981 as part of the 84 series, which aimed to offer a modern and efficient line of tractors. Production continued until 1984. Under the hood, the Hydro 84 features an International Harvester D-239 4-cylinder diesel engine, producing approximately 52 horsepower with a displacement of 239 cubic inches. A key feature was its hydrostatic transmission, offering infinite speed control within its ranges, a significant advantage over geared transmissions for tasks requiring fine adjustments. The PTO delivers around 45 horsepower at 540 RPM. Hydraulics provide a flow rate of approximately 13.5 GPM, feeding two remote valves. The 3-point hitch is a Category II, with a lift capacity of around 3,500 lbs. Common farming applications for the Hydro 84 included row crop work like planting and cultivating, hay production, livestock feeding, and light tillage. It differentiated itself from other models in the lineup through its hydrostatic transmission and its focus on providing a balance of power, efficiency, and operator comfort. While other 84 series tractors offered gear transmissions, the Hydro 84 catered to farmers who valued ease of operation and precise control.
