INTERNATIONAL HARVESTER 745 POWER
ENGINE DETAIL
The International Harvester 745 is powered by a D-239 diesel engine, delivering 72hp at 2300 RPM, with substantial torque of 185.1 lb-ft at a lower RPM of 1600, making it suitable for tasks requiring consistent power output, such as plowing or towing. The engine's displacement of 3.9L allows for efficient fuel combustion, although the 200-hour oil change interval necessitates diligent maintenance to ensure optimal performance and longevity. Operators should consider torque characteristics when matching the tractor to specific implements, as high torque at low RPM enhances pulling capacity and reduces strain on the drivetrain.

INTERNATIONAL HARVESTER 745 TIRES
The International Harvester 745 tractor features two tire configurations for different drive types: 2WD with standard agricultural tires (Front: 7.50-18, Rear: 16.9R34) and 4WD with enhanced traction (Front: 12.4R24, Rear: 16.9R34). The 4WD setup offers improved grip and stability, beneficial for challenging terrain and heavier loads, while the 2WD configuration may provide better fuel efficiency in lighter applications. Consider the operational context; for tillage or uneven fields, the 4WD is preferable, whereas for flat, well-prepared farms, the 2WD may suffice.
