Introduction
Steiger Panther III ST-310: Heavy-Duty Articulated Tractor
The Steiger Panther III ST-310 is a high-horsepower four-wheel-drive articulated tractor produced between 1976 and 1983 in Fargo, North Dakota. Designed for large-scale agricultural operations, this machine focuses on high traction capacity and robust mechanical reliability.
Engine and Performance
The tractor is powered by a Cummins NTA-855C liquid-cooled, six-cylinder turbocharged and aftercooled diesel engine. With a displacement of 14.0 liters, it produces 310 horsepower at a rated speed of 2100 RPM. The engine delivers significant torque of 980 lb-ft at 1400 RPM, providing the necessary pulling force for heavy tillage and large implement operation.
Transmission and Drivetrain
The drivetrain utilizes a four-wheel-drive system with articulated power steering for maneuverability. Transmission options include a standard 10-forward and 2-reverse Spicer SST 1010 configuration, or an optional 20-forward and 4-reverse Dana-Spicer 1010-3B setup featuring a two-speed transfer case. Both systems employ hydraulic dry disc clutches for power delivery to the Raba 598 front and rear axles.
Hydraulics and Hitch
The tractor is equipped with an open-center hydraulic system with a pump flow rate of 28.6 gpm at 2250 psi. This system supports 3 to 5 remote valves, allowing for the operation of multiple hydraulic implements. The rear hitch is a Category III type, providing compatibility with a wide array of heavy agricultural equipment.
Operator Environment and Dimensions
The Panther III ST-310 features the standard 'Safari Cab,' which includes factory-installed heating and air conditioning to maintain operator comfort. The machine measures 128 inches in wheelbase with a total length of 252 inches. Its operational weight can reach 34,000 lbs, supported by 23.1-34 agricultural tires to ensure stability in field conditions.
Conclusion
The Steiger Panther III ST-310 serves as a heavy-duty platform suited for primary cultivation and large-acreage farming. Its combination of high-torque Cummins power, multiple transmission configurations, and articulated chassis makes it a reliable choice for professional agricultural tasks requiring significant drawbar pull.
