Introduction
CaseIH STX325: Four-Wheel Drive Tractor
The CaseIH STX325 is a high-horsepower four-wheel-drive tractor produced between 2000 and 2005. Manufactured in Fargo, North Dakota, USA, this model was designed for large-scale agricultural operations requiring significant traction and power for heavy field implements.
Engine and Performance
The tractor is powered by a 540 cubic inch (8.9 L) 6-cylinder liquid-cooled turbocharged aftercooled diesel engine. It generates a rated power of 325 hp (242.4 kW) at 2000 RPM. The engine provides a peak torque of 1150 lb-ft (1559.4 Nm) at 1400 RPM, ensuring consistent performance under heavy load conditions.
Transmission and Drive
The drivetrain offers two primary configurations: a 16-speed full power shift transmission or a 24-speed fully synchronized Synchroshift transmission. Both systems utilize an electro-hydraulic wet disc clutch. Power is delivered to all four wheels through inboard planetary final drives, supported by hydrostatic power steering and integrated hydraulic wet disc brakes.
Hydraulics and Hitch
The hydraulic system features a pressure flow compensated (PFC) design with a total flow capacity of 40 gpm (151.4 lpm), with an optional capacity of 55 gpm (208.2 lpm). It supports 4 to 7 rear valves for implement control. The rear hitch is a Category IVN/III system capable of a lift capacity of 14,500 lbs (6577 kg) measured at 24 inches behind the lift point.
Operator Environment and Dimensions
Equipped with the Surveyor Cab as standard, the tractor focuses on operator ergonomics for long work days. The machine features a 139-inch wheelbase and a total length of 295.5 inches. The rear tread width is adjustable from 60 to 176 inches to accommodate various row crop configurations.
Conclusion
The CaseIH STX325 is a robust, high-capacity tractor engineered for demanding agricultural environments. Its combination of high-torque engine output, multiple transmission options, and substantial hydraulic capability makes it a suitable machine for heavy-duty primary tillage and large-scale planting applications.
