Introduction
Case IH STX275 Four-Wheel Drive Tractor
The Case IH STX275 is a high-horsepower four-wheel drive tractor produced between 2000 and 2005 at the Case IH manufacturing facility in Fargo, North Dakota, USA. Designed for large-scale agricultural operations, this machine is engineered for heavy-duty field work and high-capacity pulling requirements.
Engine Performance
The tractor is powered by an 8.3-liter, 6-cylinder turbocharged and aftercooled diesel engine. It delivers a rated power of 275 horsepower at 2000 engine RPM. The engine produces a peak torque of 1022 lb-ft at 1400 RPM, providing the necessary lugging ability for demanding tillage and heavy hauling applications. It utilizes a liquid-cooling system and dual paper element air cleaners to ensure reliability in dusty field environments.
Transmission and Drivetrain
The STX275 offers versatile drivetrain configurations to suit varying operational needs. Operators can choose between a 16-speed full power shift transmission or a 24-speed fully synchronized Synchroshift transmission. Both options utilize an electro-hydraulic wet disc clutch. Power is delivered to the ground through a four-wheel drive system featuring inboard planetary final drives and hydrostatic power steering for maneuverability.
Hydraulics and Hitch
The hydraulic system is of the pressure flow compensated (PFC) type, designed to provide efficient power to external implements. It delivers a total flow of 40 gpm (151.4 lpm), with an SCV flow capacity of 35 gpm (132.5 lpm). The rear hitch is a category IVN/III system, capable of lifting up to 14,500 lbs (6,577 kg) at 24 inches behind the lift point, allowing for the operation of heavy mounted equipment.
Operator Environment and Dimensions
The machine features the Surveyor Cab as standard equipment, focusing on operator visibility and comfort during extended field operations. With a wheelbase of 139 inches and an overall length of 295.5 inches, the tractor provides a stable footprint. The rear tread width is adjustable between 60 and 176 inches to accommodate various row spacings and stability requirements.
Conclusion
The Case IH STX275 is a robust 4WD tractor built for professional agricultural environments. Its combination of high-torque engine performance, flexible transmission options, and substantial hydraulic capacity makes it a suitable machine for large-acreage primary tillage and high-output seeding operations.
