Introduction
Case IH 4994, 4WD High-Horsepower Tractor
The Case IH 4994 is a heavy-duty four-wheel-drive tractor produced between 1984 and 1987 in Racine, Wisconsin. Designed for large-scale agricultural operations, this model represents the high-power segment of the 4000 series, offering substantial drawbar performance and advanced operator features for its era.
Engine and Performance
The tractor is powered by a liquid-cooled, 8-cylinder engine with a displacement of 866 cubic inches (14.2 liters). It produces a rated power of 400 hp (298.3 kW) at 2100 RPM and delivers a peak torque of 1,140 lb-ft (1545.8 Nm) at 1300 RPM. The engine cooling system has a capacity of 83.3 liters, and it utilizes a dual paper element air cleaner system to maintain combustion efficiency in dusty field conditions.
Transmission and Driveline
The 4994 features a full powershift transmission providing 12 forward and 2 reverse gears, branded as the Case Powergard PTF. It is operated via a single control lever and an inching pedal, which is required for engagement from neutral. The system includes hydraulic wet disc clutches and requires 59.6 liters of oil for operation. Power is delivered to the ground through a 4x4 all-wheel-drive system.
Hydraulics and PTO
The hydraulic system utilizes a closed-center design with a total flow capacity of 35 gpm (132.5 lpm), providing 2000 psi (137.9 bar) of pressure. It is equipped with four valves to manage various implements. An independent rear PTO is available as an option, delivering 1000 RPM at an engine speed of 2100 RPM.
Dimensions and Handling
Built on a 316 cm wheelbase, the tractor has an overall length of 664 cm and a height of 351 cm to the top of the exhaust. The steering system is fully hydraulic, supporting front, rear, or four-wheel crab steering modes, which enhances maneuverability for a machine of this scale. The operator is housed within the standard Silent Guardian cab, designed for increased comfort during extended operation.
Conclusion
With only 224 units manufactured, the Case IH 4994 remains a significant machine for collectors and large-acreage farmers requiring high-traction capabilities. Its combination of a 400 hp engine and versatile steering configurations makes it suitable for heavy primary tillage and demanding field work.
