ENGINE DETAIL

The Farmall 1456 features a robust International Harvester DT407 turbocharged diesel engine with a displacement of 6.7L, providing ample power for heavy-duty agricultural tasks, especially at its rated RPM of 2400. Its high compression ratio of 17:1 contributes to improved efficiency and torque output, while the dual dry element air cleaner enhances filtration and engine longevity. However, with an oil capacity of 13 quarts, maintenance intervals must be closely monitored to prevent engine wear, and the relatively large coolant capacity of 24 quarts indicates a significant cooling requirement, especially under strenuous operations.
