ENGINE DETAIL
The Steiger Tiger III ST-470 features a robust Cummins KTA-1150 engine, offering 470 horsepower at 1700 RPM, making it suitable for heavy field work under demanding conditions. Its impressive torque of 1580 lb-ft at 1500 RPM provides excellent pulling power, essential for tasks like tilling or heavy hauling. However, the substantial oil (76 qts) and coolant (112 qts) capacities imply that maintenance routines may be resource-intensive, necessitating careful monitoring to ensure optimal performance and longevity.
