INTERNATIONAL HARVESTER 743 POWER
ENGINE DETAIL
The International Harvester 743 features a robust D-329 diesel engine, providing 67 hp, making it suitable for medium-duty agricultural tasks. Its displacement of 3.9L and bore/stroke ratio indicate a torque-focused design, which enhances its performance in heavy pulling scenarios. However, at a rated RPM of 2300, its power delivery may limit high-speed operations, making it ideal for applications requiring endurance rather than speed.

INTERNATIONAL HARVESTER 743 TIRES
The International Harvester 743 tractor offers both 2WD and 4WD configurations, allowing versatility depending on terrain and workload; 4WD enhances traction in muddy or uneven ground, making it ideal for tough agricultural tasks. The tire size options—7.50-16 on the front and 16.9/14-30 on the rear for 2WD, and 9.5/9-24 front with 16.9/14-30 rear for 4WD—provide a good balance of stability and load-bearing capacity. However, 4WD may increase maintenance complexity and operational costs while providing the advantage of improved off-road performance.
