ENGINE DETAIL
The CaseIH STX480 tractor features a robust Cummins QSX15 engine, delivering 480hp at a relatively low rated RPM of 2000, which optimizes torque performance for heavy-duty applications. Its large displacement of 14.9L combined with a dual paper element air cleaner aids in maintaining engine efficiency under high-load conditions, although the complexity of the aftercooled turbocharged system may require careful monitoring for maintenance. Ideal for large agricultural operations, this tractor offers high power but may present challenges in fuel efficiency and increased operational costs compared to lower-horsepower counterparts.
