Introduction
Steiger Panther III PT-350 Four-Wheel Drive Tractor
The Steiger Panther III PT-350 is a high-horsepower, four-wheel drive tractor produced between 1977 and 1981. Manufactured in Fargo, North Dakota, this machine was designed for large-scale agricultural operations requiring significant traction and heavy-duty performance.
Engine and Performance
The tractor is powered by a Cummins VT903, a turbocharged 14.8-liter V-8 diesel engine. It generates 350 horsepower at a rated speed of 2600 RPM. The liquid-cooled unit features a compression ratio of 15.5:1, providing the torque necessary for deep tillage and heavy pulling tasks.
Transmission and Drivetrain
The powertrain utilizes a constant mesh transmission offering 20 forward and 4 reverse gears. It incorporates a five-speed main transmission with two ranges and a two-speed transfer case. The system uses a hydraulic cerametallic dry disc clutch, requiring the tractor to be fully stopped before shifting between ranges.
Hydraulics and PTO
The hydraulic system is an open-center design providing a pump flow of 20 gpm (75.7 lpm) at a pressure of 2250 psi. Equipped with 4 or 5 valves, it supports various implements. The optional rear independent PTO provides 540 and 1000 RPM speeds, controlled by a hydrostatic-drive clutch.
Chassis and Operator Environment
The tractor features an articulated power steering system for maneuvering its substantial frame, which rests on a 132.5-inch wheelbase. Braking is handled by hydraulic disc brakes. The operator occupies a standard Safari Cab, which includes air conditioning as factory equipment to maintain climate control during long operational periods.
Conclusion
The Steiger Panther III PT-350 is a robust, heavy-frame tractor engineered for demanding field work. With its significant weight and articulated 4WD configuration, it remains a notable example of late 1970s agricultural engineering, suited for primary cultivation and large-acreage farming.
