Introduction
Case 4490: High-Capacity Four-Wheel Drive Tractor
The Case 4490 is a high-horsepower four-wheel drive tractor produced by J.I. Case in Racine, Wisconsin, between 1979 and 1983. Designed for large-scale agricultural operations, this model emphasizes traction, heavy-duty lifting, and operator comfort.
Engine and Performance
The tractor is powered by a 504 cubic inch (8.3 L) 6-cylinder turbocharged diesel engine. It operates at a rated speed of 2200 RPM and produces 210 horsepower (156.6 kW). The engine utilizes a liquid-cooling system and a dual-element paper air cleaner to maintain performance under demanding conditions, supported by a 15.8:1 compression ratio.
Transmission and Drive System
The drivetrain features a three-speed power shift transmission providing 12 forward and 4 reverse gears. It utilizes a hydraulic wet disc clutch to facilitate smooth gear transitions. The machine is a 4x4 four-wheel drive system equipped with power four-wheel steering and outboard planetary final drives, ensuring significant pulling power and maneuverability in the field.
Hydraulics and PTO
The hydraulic system is of a closed-center type, providing a pump flow of 31 gpm (117.3 lpm) and an SCV flow of 24 gpm (90.8 lpm) at 2250 psi. It supports between 2 and 4 valves for implement control. The rear PTO is an independent unit operating at 1000 RPM (1.375 inch shaft), suitable for high-demand power-take-off implements.
Operator Environment and Dimensions
The tractor is equipped with the Silent Guardian cab as standard, which includes air conditioning to manage the operator environment during long shifts. With an operating weight of 20,840 lbs (9,453 kg) and a ballasted weight reaching up to 22,450 lbs (10,183 kg), it provides the stability required for heavy draft work. The wheelbase measures 102 inches, and the rear Category III hitch offers a lift capacity of 11,000 lbs (4,989 kg).
Conclusion
The Case 4490 is a robust, heavy-duty tractor engineered for significant traction and implement management. Its combination of a 210-horsepower engine, four-wheel steering, and high-capacity hydraulic system makes it a well-suited machine for large-acreage farming and heavy tillage applications.
