Case IH 4690 Tractor Parts

4690 parts and accessories

The Case IH 4690 tractor, manufactured from 1978 to 1981, was a powerful articulated four-wheel drive machine popular with farmers needing high horsepower for demanding tasks. Featuring a robust 300 HP turbocharged diesel engine, and delivering around 240 PTO horsepower, the 4690 was prized for its ability to handle large implements and cover ground quickly.

The Case IH 4690 was introduced in 1978 as part of the expansion of Case IH's large frame four-wheel drive tractor lineup. Production continued until 1981. It was designed to provide substantial power for large-scale farming operations. The tractor is powered by a Cummins V-8 diesel engine producing around 300 horsepower. Engine displacement is around 855 cubic inches. This model features a robust 12-speed manual transmission, offering a wide range of speeds for various field conditions. The PTO horsepower is rated at approximately 240 HP, available at 1000 RPM. Hydraulic capacity is significant, providing ample flow for large implements, typically around 45 GPM with multiple remote valves. While not equipped with a standard 3-point hitch, it could be outfitted with an optional hitch, typically a Category III. Common applications included primary tillage, pulling large planters and air seeders, and heavy row crop work. What distinguishes the 4690 from other models in the Case IH lineup of the time was its blend of raw power and relatively simple mechanical design, making it a reliable workhorse for its era.
