ENGINE DETAIL
The Steiger Cougar III PT-250 is powered by a robust Caterpillar 3306T turbocharged diesel engine, offering 250hp at a rated RPM of 2200, making it well-suited for heavy-duty agricultural tasks. With a displacement of 10.5L and impressive torque, it can manage challenging terrains, though its relatively high compression ratio of 17.5:1 requires high-quality diesel to avoid knocking. Key maintenance considerations include its oil and coolant capacities of 26 quarts and 52 quarts, respectively, to ensure optimal performance and longevity.

STEIGER COUGAR III PT-250 TIRES
The Steiger Cougar III PT-250 features Ag front tires of 23.1x30 and a versatile range of rear tire options, allowing for customization based on specific operational needs and soil conditions. The larger rear tire options, like 30.5x32 and 20.8x38, can enhance traction and stability in challenging terrains but may increase soil compaction. Consider your typical field conditions and required stability to optimize tire selection for effective performance.
