Introduction
Steiger Bearcat II ST-225 Agricultural Tractor
The Steiger Bearcat II ST-225 is a heavy-duty four-wheel drive tractor manufactured in Fargo, North Dakota, between 1974 and 1976. This machine was designed to provide high-traction performance for large-scale agricultural operations.
Engine and Powertrain
The tractor is powered by a Caterpillar 3208 liquid-cooled diesel engine. This 8-cylinder unit features a displacement of 636 cubic inches (10.4 liters) and produces 225 horsepower at a rated engine speed of 2800 RPM. It delivers 485 lb-ft of torque at 1400 RPM, providing the necessary force for heavy draft applications. Power is managed through a Dana-Spicer ST-1010 gear transmission offering 10 forward and 2 reverse speeds, coupled with a 355.6 mm cerametallic clutch.
Hydraulics and Hitch
The hydraulic system utilizes an open-center design with a pump flow capacity of 22 gallons per minute (83.3 lpm) and an operating pressure of 2000 psi. The system includes a 30-gallon (113.6 L) reservoir and supports three valves for implement control. Steering is assisted by a dedicated circuit operating at 1500 psi. A Category III rear hitch is available as an optional feature to accommodate heavy implements.
Mechanical Configuration and Dimensions
Built on an articulated chassis, the Bearcat II ST-225 employs articulated power steering for maneuverability despite its 118-inch (299 cm) wheelbase. The tractor features hydraulic disc brakes and outboard planetary final drives. The total machine weight is 21,500 lbs (9,752 kg), with an overall length of 228 inches (579 cm) and a width of 96 inches (243 cm) when equipped with 23.1 tires.
Conclusion
With its robust Caterpillar engine and articulated four-wheel drive architecture, the Steiger Bearcat II ST-225 is engineered for high-demand field work. It remains a notable example of 1970s American tractor design, prioritizing raw tractive power and structural durability for large farming enterprises.
