Introduction

J.I. Case 4890 Four-Wheel Drive Tractor

The J.I. Case 4890 is a heavy-duty four-wheel drive tractor produced between 1979 and 1983 in Racine, Wisconsin. Designed for large-scale agricultural operations, this model represents a significant entry in the Case 4800 series, known for its high power output and structural durability.

Engine and Performance

The tractor is powered by a Saab-Scania 6-cylinder turbocharged diesel engine. With a displacement of 674 cubic inches (11.0 liters) and a compression ratio of 14.7:1, it generates 300 horsepower at a rated engine speed of 2200 RPM. The liquid-cooled system ensures thermal stability during sustained heavy-load operations, supported by a 44-quart coolant capacity.

Transmission and Drivetrain

The 4890 utilizes a partial powershift transmission providing 12 forward and 4 reverse gears. It features four distinct ranges with three power shifts available within each range, allowing for efficient speed adjustments under load. The drivetrain is a 4x4 system, paired with a hydraulic dry disc clutch for power engagement.

Hydraulics and Hitch

Equipped with a closed-center Pressure Flow Compensating (PFC) hydraulic system, the tractor delivers a total flow of 31 gallons per minute (117.3 lpm) at a pressure of 2250 psi. It includes 2 to 4 valves for implement control. The rear hitch is a Category III type with a lift capacity of 12,750 lbs (5,783 kg), making it compatible with a wide range of heavy implements.

Operator Environment and Steering

The operator is housed in the Silent Guardian cab, which comes standard with air-conditioning to mitigate environmental stress. Steering is managed by a hydraulic system capable of front, rear, or four-wheel crab steering, providing the maneuverability required for a machine with a 110-inch wheelbase.

Conclusion

"With an operating weight of 25,750 lbs and the ability to be ballasted up to 28,460 lbs, the J.I. Case 4890 is designed for heavy traction and intensive field work. Its combination of high-capacity hydraulics, multi-mode steering, and robust engine performance makes it a substantial asset for large-acreage farming applications."
