Introduction
Steiger Panther III PTA-310: Heavy-Duty 4WD Tractor
The Steiger Panther III PTA-310 is a high-capacity four-wheel-drive tractor manufactured in Fargo, North Dakota, between 1980 and 1982. Designed for large-scale agricultural operations, this machine represents the heavy-duty engineering standard of the early 1980s.
Engine and Power
The tractor is powered by a Cummins NTA-855C liquid-cooled, inline 6-cylinder diesel engine. This unit features turbocharging and aftercooling, with a displacement of 855 cubic inches (14.0 liters). It delivers 310 horsepower at a rated engine speed of 2100 RPM, providing a peak torque of 980 lb-ft at 1400 RPM.
Transmission and Drivetrain
Power is transferred via an Allison HT-754 power shift transmission equipped with a torque converter. The drivetrain provides 10 forward and 2 reverse gears, allowing for precise speed control. The machine utilizes a four-wheel-drive system with articulated power steering and outboard planetary final drives to maximize tractive effort.
Hydraulics and PTO
The hydraulic system is an open-center configuration, delivering a pump flow of 28.6 gpm at a system pressure of 2250 psi. It supports 3 to 5 remote valves for implement control. The rear PTO is independent, offering selectable speeds of 540 or 1000 RPM to accommodate various implements.
Dimensions and Operator Environment
With a wheelbase of 132.5 inches and a total shipping weight of 28,400 lbs, the tractor is engineered for stability under heavy loads. It features the standard Safari Cab, which includes factory-installed air conditioning to enhance operator comfort during extended field operations. Braking is handled by hydraulic disc brakes.
Conclusion
The Steiger Panther III PTA-310 is a robust, high-horsepower tractor tailored for heavy tillage and large-scale traction requirements. Its combination of a high-torque Cummins engine and a multi-gear power shift transmission makes it a reliable asset for intensive agricultural environments.
