ENGINE DETAIL
The International Harvester A-414 features a robust AD-154 diesel engine with a high compression ratio of 22:1, delivering 40 hp at 2000 RPM, and a strong torque of 115 lb-ft at 1300 RPM, making it suitable for high-load applications such as plowing and tilling. Its compact 2.5L displacement and liquid cooling system enhance thermal efficiency, though the oil capacity of 4.64 quarts suggests regular maintenance will be essential to avoid engine wear. Ideal for small to medium farms, the tractor balances power and efficiency, but its 12-volt starting system might necessitate battery management to ensure reliability during extended use.
