Introduction
Case 4494 Four-Wheel Drive Tractor
The Case 4494 is a heavy-duty four-wheel drive tractor produced by J.I. Case in Racine, Wisconsin, between 1984 and 1987. As part of the 4494 series, this machine was engineered for demanding agricultural applications, prioritizing high torque output and structural stability.
Engine and Performance
The tractor is powered by a 6-cylinder, 8.3-liter (504 ci) turbocharged diesel engine. This unit generates a rated output of 213 horsepower (158.8 kW) at 2200 RPM. It is characterized by a significant torque peak of 560 lb-ft (759.4 Nm) achieved at 1650 RPM, which provides the necessary lugging ability for heavy draft operations. The engine utilizes a liquid-cooling system and a dual-element paper air cleaner to maintain operational efficiency under field conditions.
Transmission and Drivetrain
Power is transferred through a partial power shift transmission offering 12 forward and 4 reverse gears. The system consists of four ranges with three power shift gears in each range, managed by dashboard-mounted levers. A hydraulic wet disc clutch facilitates gear changes. The tractor features a 4WD configuration, supported by hydraulic steering capable of front, rear, or four-wheel crab steering modes to improve maneuverability.
Hydraulics and Hitch
The Case 4494 employs a closed-center hydraulic system with a total flow capacity of 31 gpm (117.3 lpm) at a system pressure of 2350 psi (162.0 bar). It supports between two and four remote valves. The rear Category III hitch provides a lift capacity of 12,750 lbs (5783 kg) at 24 inches behind the hitch point, allowing for the attachment of heavy implements.
Dimensions and Operator Environment
Designed for stability, the tractor has a wheelbase of 102 inches and an operating weight of 20,840 lbs (9453 kg), which can be increased to 22,450 lbs (10183 kg) with ballast. The operator environment includes the standard 'Silent Guardian' cab, designed to reduce noise and vibration during long shifts. Braking is provided by hydraulic dry disc brakes.
Conclusion
The Case 4494 is a robust, high-horsepower tractor tailored for large-scale farming operations requiring consistent drawbar power and hydraulic versatility. Its combination of a high-torque engine and flexible steering options makes it a capable solution for primary tillage and heavy implement work.
