Introduction
Steiger Panther III ST-325: Heavy-Duty Articulated 4WD Tractor
The Steiger Panther III ST-325 is a high-horsepower four-wheel-drive tractor manufactured in Fargo, North Dakota, between 1976 and 1983. Designed for large-scale agricultural operations, this machine focuses on high-torque traction and heavy-duty field performance.
Engine and Performance
The tractor is powered by a Caterpillar 3406DIT, a 14.6-liter, 6-cylinder turbocharged diesel engine. It generates 325 horsepower at a rated speed of 2100 RPM. The engine is tuned for high torque output, providing 1015 lb-ft at 1200 RPM, which allows the machine to maintain consistent speed under heavy draft loads.
Transmission and Drive
The drivetrain features an articulated steering system for improved maneuverability. Power is delivered to the wheels through a choice of transmission configurations: a standard 10-speed or an optional 20-speed transmission, both incorporating a two-speed transfer case. Braking is managed by hydraulic disc brakes, and final drives utilize an outboard planetary design to handle the high torque requirements.
Hydraulics and Hitch
The tractor is equipped with an open-center hydraulic system providing a pump flow of 31.9 GPM (120.7 lpm) at a pressure of 2250 psi. This system supports three to five control valves, allowing for the operation of complex implements. A Category III rear hitch is available as an option to interface with various heavy-duty agricultural tools.
Dimensions and Operator Environment
The Panther III ST-325 features a wheelbase of 128 inches and a shipping weight of 26,900 lbs, which can reach a maximum weight of 34,000 lbs depending on ballast. The operator operates within the standard 'Safari Cab,' which includes factory-installed heating and air conditioning to maintain comfort during extended field operations.
Conclusion
The Steiger Panther III ST-325 serves as a robust platform for farmers requiring significant pulling power for primary tillage and large-scale cultivation. Its mechanical simplicity, combined with the high-torque Caterpillar engine, makes it a reliable choice for heavy agricultural applications from the late 1970s and early 1980s.
