Introduction
Steiger Panther II ST-310: Heavy-Duty Articulated Tractor
The Steiger Panther II ST-310 is a four-wheel drive tractor manufactured by Steiger in Fargo, North Dakota, between 1974 and 1976. Designed for large-scale agricultural operations, this machine belongs to the high-horsepower segment of its era, prioritizing traction and pulling power.
Engine and Performance
The tractor is powered by a Cummins NT-855-C310 turbocharged liquid-cooled diesel engine. This 6-cylinder unit features a 14.0-liter displacement with a 14:1 compression ratio. It produces 310 horsepower at a rated speed of 2100 RPM, with a peak torque of 890 lb-ft (1206.8 Nm) at the same engine speed, providing consistent power delivery for heavy tillage and traction tasks.
Transmission and Drivetrain
The drivetrain utilizes a Dana-Spicer 1010 transmission system, offering a total of 10 forward gears and 2 reverse gears distributed across two ranges. Power is transmitted to all four wheels through an articulated steering system, complemented by outboard planetary final drives. Braking is handled by hydraulic disc brakes, ensuring control for a machine with a maximum weight capacity of 29,000 lbs (13,154 kg).
Hydraulics and Dimensions
The hydraulic system is an open-center configuration with a pump flow rate of 20.6 gpm (78.0 lpm) at a pressure of 2000 psi. A separate circuit provides 23.5 gpm for the articulated power steering. The tractor features a 122-inch wheelbase and a total length of 235 inches, providing a stable platform for field operations. The standard cab includes heating and optional air conditioning to support operator endurance.
Conclusion
With its robust Cummins engine, substantial weight, and articulated four-wheel drive architecture, the Steiger Panther II ST-310 is engineered for heavy-duty field work and large-scale agricultural traction requirements.
