ENGINE DETAIL
The Steiger Panther III ST-350, powered by a Cummins VT-903 turbocharged diesel engine, offers a substantial power output of 350 hp at a rated RPM of 2600, alongside a high torque value of 848 lb-ft at 1800 RPM, ideal for heavy-duty field tasks. Its considerable displacement of 14.8L and a robust compression ratio of 15.5:1 enhance fuel efficiency and performance under heavy loads. However, the tractor's large oil and coolant capacities (38qts and 68qts respectively) highlight the need for diligent maintenance and monitoring to optimize engine longevity and prevent overheating during prolonged operations.
