INTERNATIONAL HARVESTER 484 ENGINE
The International Harvester 484 is powered by a robust 2.9L 3-cylinder diesel engine, offering a balance of efficiency and torque for various agricultural tasks. Its compact design enhances maneuverability in tighter fields, while the diesel engine provides lower fuel consumption compared to larger models, beneficial for long hours of operation. However, the 3-cylinder configuration may result in less power output compared to 4-cylinder counterparts, which could limit its performance in heavy-duty applications.
