ENGINE DETAIL
The Steiger Cougar IV CM-250 features a Caterpillar 3306 turbocharged diesel engine that delivers robust power of 250 hp at 2100 RPM and an impressive torque of 860 lb-ft at 1300 RPM, making it well-suited for demanding agricultural applications. Its large displacement of 10.5L provides significant load-carrying capacity, while the oil and coolant capacities of 29 and 56 quarts respectively ensure effective temperature management during extended operations. However, the engine's operating range of 1700-2100 RPM requires careful matching to implement demands, as exceeding this could lead to decreased efficiency or potential engine strain.
