Introduction
Case IH STX375QT Articulated Crawler Tractor
The Case IH STX375QT is a high-horsepower articulated crawler tractor manufactured between 2002 and 2005 in Fargo, North Dakota, USA. Designed for heavy-duty agricultural applications, this machine utilizes a specialized track-drive system to maximize traction and reduce soil compaction during demanding field operations.
Engine and Performance
The tractor is powered by a 6-cylinder, 15.0-liter turbocharged and aftercooled diesel engine. It generates 375 horsepower (279.6 kW) at a rated speed of 2000 RPM. The engine produces a maximum torque of 1380 lb-ft (1871.3 Nm) at 1400 RPM, providing the necessary pulling force for large-scale implements.
Transmission and Drive
The STX375QT is equipped with a full power shift transmission offering 16 forward and 2 reverse gears. This system features an electro-hydraulic wet disc clutch, allowing for seamless gear changes under load. The machine utilizes an articulated crawler drive configuration with inboard planetary final drives to distribute power effectively to the 30-inch tracks.
Hydraulics and Hitch
The hydraulic system is of the pressure flow compensated (PFC) type, featuring a standard pump flow of 40 gpm (151.4 lpm), with an optional capacity of 55 gpm (208.2 lpm). It supports between 4 and 7 rear valves to operate various hydraulic implements. The rear hitch is a category IVN/III type with a lift capacity of 19,500 lbs (8,845 kg) measured at 24 inches behind the lift point.
Operator Environment
Standard equipment includes the Surveyor Cab, engineered to provide visibility and operator comfort during extended field shifts. The tractor utilizes hydrostatic power steering to manage its articulated frame and integrated hydraulic wet disc brakes to ensure controlled stopping performance.
Conclusion
The Case IH STX375QT is a robust, high-performance crawler tractor engineered for large-acreage farming. Its combination of high torque, track-based traction, and significant hydraulic capacity makes it suitable for heavy primary tillage and intensive cultivation tasks.
