Introduction
Steiger Cougar IV KS-280: Heavy-Duty 4WD Tractor
The Steiger Cougar IV KS-280 is a high-horsepower four-wheel drive tractor manufactured between 1984 and 1985 in Fargo, North Dakota, USA. Designed for large-scale agricultural operations, this model represents a specialized segment of heavy-duty traction machines built for demanding field conditions.
Engine and Performance
The tractor is powered by a Cummins NT-855 liquid-cooled, inline 6-cylinder turbocharged diesel engine. With a displacement of 855 cubic inches (14.0 liters), it generates 280 horsepower at a rated speed of 2100 RPM. The engine produces 910 lb-ft of torque at 1400 RPM, providing the necessary pulling force for heavy tillage and draft work.
Transmission and Drivetrain
Power is transferred through an Allison HT 754CRD power shift transmission, offering 10 forward and 2 reverse gears. The drivetrain features articulated power steering and outboard planetary final drives, which are standard configurations for high-torque four-wheel drive articulated tractors of this era.
Hydraulics and Hitch
The machine utilizes an open-center hydraulic system operating at a pressure of 2250 psi. The pump delivers a flow rate of 28.6 gpm, supporting between 3 and 5 valves to manage various hydraulic implements. A Category III rear hitch is available to facilitate the attachment of heavy-duty farming equipment.
Operator Environment and Dimensions
The tractor is equipped with a standard cab that includes air conditioning. With a wheelbase of 132.5 inches and a shipping weight of 25,902 lbs, the machine is designed for stability. It can reach a maximum operational weight of 34,000 lbs, allowing for significant ballast to maximize traction in the field.
Conclusion
The Steiger Cougar IV KS-280 is a robust, high-capacity tractor engineered for demanding traction tasks. Its combination of a high-torque Cummins engine and an articulated 4WD chassis makes it a suitable machine for large-scale primary cultivation and heavy-duty field operations.
