Introduction
Case 1594 Utility Tractor
The Case 1594 is a utility tractor manufactured between 1985 and 1988. Designed for versatility in agricultural operations, it represents the continuation of the Case 94 series, offering reliable power and various configuration options to suit different field requirements.
Engine and Performance
The tractor is powered by a 5.4-liter, 6-cylinder liquid-cooled diesel engine manufactured by Case. It produces 97 horsepower at a rated engine speed of 2300 RPM. The engine delivers 242.7 lb-ft of torque at 1425 RPM, providing the necessary pulling power for standard agricultural tasks. It features a compression ratio of 16:1 and utilizes a dual-element air cleaner with a pre-cleaner for improved longevity in dusty environments.
Transmission and Drivetrain
Operators can choose between two transmission configurations: a 12-speed synchromesh gearbox or a 12-speed Hydra-Shift partial power shift transmission. Both variants provide 12 forward and 4 reverse gears. The tractor is available in a 4x2 2WD configuration, with an optional 4x4 MFWD (Mechanical Front Wheel Drive) system for enhanced traction in difficult terrain.
Hydraulics and Hitch
The Case 1594 utilizes an open-center hydraulic system operating at a system pressure of 2600 psi, with a dedicated steering flow of 7.7 GPM and a total hydraulic flow of 10.5 GPM. It is equipped with two hydraulic valves. The rear hitch is a Category II type, capable of lifting up to 7,440 lbs at the link ends, making it suitable for a wide range of mounted implements.
Dimensions and Handling
The machine features a 100-inch wheelbase and provides a ground clearance of 16 inches for the 2WD model. It is equipped with hydrostatic power steering and differential hydraulic wet disc brakes, ensuring controlled handling during field work and transport. The tractor can be fitted with various agricultural tire combinations to optimize performance based on the specific terrain.
Conclusion
The Case 1594 is a robust utility tractor engineered for durability and operational flexibility. Its combination of a 97-horsepower engine, multiple transmission options, and substantial hitch capacity makes it a practical choice for general farming duties and medium-duty tractive tasks.
