Introduction
Steiger Cougar III PTA-270 Four-Wheel Drive Tractor
The Steiger Cougar III PTA-270 is a heavy-duty four-wheel-drive tractor produced in Fargo, North Dakota, between 1980 and 1981. Designed for large-scale agricultural operations, this machine represents the high-capacity engineering typical of the era's articulated tractors.
Engine and Performance
The tractor is powered by a Caterpillar 3306TA, a 10.5-liter, six-cylinder turbocharged and aftercooled diesel engine. It generates a rated 270 horsepower at 2200 RPM and produces 775 lb-ft of torque at 1400 RPM. This power plant is liquid-cooled and features a 17.5:1 compression ratio, providing the sustained pulling capacity required for heavy tillage and field work.
Transmission and Drivetrain
Power is transferred through an Allison HT 754 transmission, which offers 10 forward and 2 reverse gears. The drivetrain features articulated power steering and outboard planetary final drives to manage the torque output. The tractor operates as a full-time four-wheel-drive unit, utilizing hydraulic disc brakes for stopping power.
Hydraulics and Hitch
The hydraulic system is an open-center design with a pump flow capacity of 29.2 gpm (110.5 lpm). It includes four valves and an SCV flow of 20 gpm (75.7 lpm), allowing for the operation of multiple hydraulic implements. An optional Category III rear hitch is available for heavy-duty implement attachment.
Dimensions and Operator Environment
With a wheelbase of 132.5 inches and a base operating weight of 25,500 lbs, the Cougar III PTA-270 is built for stability and traction. The operator is housed in the Safari Cab, which was supplied as standard equipment with integrated air conditioning to maintain comfort during extended field operations.
Conclusion
The Steiger Cougar III PTA-270 is a robust, high-horsepower tractor engineered for demanding agricultural environments. Its combination of a proven Caterpillar engine, articulated steering, and heavy-duty drivetrain makes it a suitable machine for large-acreage farming and heavy pulling applications.
