Introduction
Steiger Tiger III ST-470 Four-Wheel Drive Tractor
The Steiger Tiger III ST-470 is a heavy-duty four-wheel-drive tractor manufactured in Fargo, North Dakota, between 1980 and 1982. Designed for large-scale agricultural operations, this machine represents a significant era in high-horsepower tractor engineering, focusing on traction, durability, and raw power output.
Engine and Performance
The tractor is powered by a Cummins 6-cylinder, liquid-cooled inline engine with a displacement of 1150 cubic inches (18.8 liters). It produces a rated output of 470 horsepower. The engine is characterized by a high torque capacity, delivering 1580 lb-ft (2142.5 Nm) at 1500 RPM, which provides the necessary force for heavy-duty pulling and field work.
Transmission and Drivetrain
Power is managed through an Allison CLT 5965 transmission, a full power-shift unit offering 6 forward gears and 1 reverse gear. It features a locking torque converter that automatically engages once the transmission reaches 1700 RPM, optimizing power delivery to the wheels under load. The tractor utilizes a four-wheel-drive system with articulated power steering for improved maneuverability.
Hydraulics and Operator Environment
The hydraulic system is of the open-center type, featuring a pump flow capacity of 38 gallons per minute (143.8 lpm) at a operating pressure of 2250 psi. It is equipped with five valves to support various implements. The operator is housed in a standard Safari Cab, which includes factory-installed air conditioning to maintain comfort during extended field operations.
Dimensions and Weight
With a wheelbase of 150 inches (381 cm) and an overall length of 289 inches (734 cm), the ST-470 is a substantial machine. Its base weight is 45,360 lbs (20,575 kg), with a maximum weight capacity of 50,000 lbs (22,680 kg). It is fitted with 30.5x32 tires on both front and rear axles to manage its mass and provide necessary flotation.
Conclusion
The Steiger Tiger III ST-470 is engineered for demanding agricultural tasks that require high torque and reliable four-wheel-drive traction. Its robust mechanical construction and specialized transmission make it a suitable choice for large-acreage farming and heavy-duty primary tillage applications.
