ENGINE DETAIL
The Steiger Bearcat III ST-225 is powered by a Caterpillar 3306DIT turbocharged diesel engine, providing robust performance with 225hp at 2100 RPM and impressive torque of 730 lb-ft at 1300 RPM, ideal for heavy-duty agricultural tasks. Its 10.5L displacement and high compression ratio of 15:1 enhance fuel efficiency and power delivery; however, maintenance of such a high-capacity engine can be challenging due to its complexity and oil capacity of 29 quarts. This tractor is well-suited for large-scale operations where reliable power and torque are essential for demanding tasks, like plowing or heavy lifting.
