Introduction
Case 4994 Four-Wheel Drive Tractor
The Case 4994 is a high-horsepower four-wheel drive tractor manufactured by J.I. Case in Racine, Wisconsin, between 1984 and 1987. Designed for heavy-duty agricultural operations, this machine belongs to the 4994 series and represents a high-capacity solution for large-scale farming requirements.
Engine and Performance
The tractor is powered by an 8-cylinder, liquid-cooled engine with a displacement of 14.2 liters (866 ci). It produces a rated output of 400 horsepower (298.3 kW) at 2100 engine RPM. The engine delivers a significant torque of 1140 lb-ft (1545.8 Nm) at 1300 RPM, providing the necessary force for heavy traction tasks. The compression ratio is set at 15.5:1.
Transmission and Drive
Equipped with an electronically controlled full powershift transmission, the 4994 offers 12 forward and 2 reverse gears. The system is operated via a single control lever and an inching pedal, which is required to shift from park or neutral into first gear. The tractor features a 4x4 all-wheel-drive configuration and includes hydraulic dual caliper disc brakes for stopping power.
Hydraulics and Steering
The hydraulic system utilizes a closed-center design with a total pump flow of 35 gpm (132.5 lpm) and a system pressure of 2000 psi. It supports 2 to 4 valves for implement operation. The steering system is hydraulic and offers multiple modes, including front, rear, or four-wheel crab steering, providing enhanced maneuverability for a machine of this size.
Dimensions and Capacity
The Case 4994 features a wheelbase of 124.8 inches (316 cm) and a total length of 261.8 inches (664 cm). It is equipped with a rear hitch of category IV/IVN, capable of lifting up to 16,000 lbs (7257 kg) at 24 inches behind the lift point. The operator environment is provided by the standard Silent Guardian cab.
Conclusion
With only 224 units produced, the Case 4994 remains a notable example of 1980s heavy-duty agricultural engineering. Its combination of high engine torque, versatile steering modes, and substantial lift capacity makes it well-suited for demanding field work and heavy implement management.
