Introduction
Case IH STX440QT Articulated Crawler Tractor
The Case IH STX440QT is a high-horsepower articulated crawler tractor manufactured in Fargo, North Dakota, between 2002 and 2005. It belongs to the STX series, designed for heavy-duty agricultural operations requiring high tractive effort.
Engine and Performance
The machine is powered by a 14.9-liter, 6-cylinder turbocharged and aftercooled diesel engine. It delivers a rated power of 440 hp at 2000 RPM. The engine is tuned for high-torque applications, providing 1650 lb-ft of torque at 1400 RPM, which is essential for deep tillage and heavy pulling tasks.
Transmission and Drive
The tractor features a full power shift transmission with 16 forward and 2 reverse gears, allowing for on-the-go shifting without interrupting power delivery. The drive system consists of an articulated crawler configuration, utilizing inboard planetary final drives to manage the high torque output efficiently.
Hydraulics and Hitch
Equipped with a closed-center load-sensing hydraulic system, the STX440QT provides a pump flow of 40 gpm. It includes 4 to 7 rear remote valves to operate various implements. The rear hitch is a Category IVN type, capable of a lift capacity of 19,500 lbs at 24 inches behind the lift point.
Operator Environment and Controls
The tractor is equipped with the Surveyor Cab as standard, designed for long-duration operation. Steering is managed by a hydrostatic power system, and stopping power is provided by integrated hydraulic wet disc brakes, ensuring controlled operation of the 23,285 kg machine.
Conclusion
The Case IH STX440QT is engineered for large-scale farming environments where high tractive efficiency and heavy-duty implement management are required. Its combination of an articulated crawler chassis and high-torque engine makes it suitable for demanding field conditions.
