INTERNATIONAL HARVESTER 724 POWER
ENGINE DETAIL
The International Harvester 724 features a D-239 diesel engine with a 3.9L displacement, generating 67hp at 2200 RPM, allowing for moderate power output suitable for various agricultural applications. Its direct injection and high compression ratio (16:1) enhance fuel efficiency, while the torque peak at 1600 RPM (165 lb-ft) supports heavy loads during low-speed operations. However, the limited idle RPM range (650-2420) may challenge adaptability for varying tasks, necessitating operator skill for optimal engine performance.

INTERNATIONAL HARVESTER 724 ENGINE
The International Harvester 724 tractor features a robust 3.9L 4-cylinder diesel engine, ensuring efficient fuel consumption and reliable torque for various agricultural tasks. With an 18.5-gallon fuel tank, operators can benefit from extended runtimes, minimizing downtime during demanding operations. However, the relatively small engine displacement may limit its performance in heavy-duty applications, making it ideal for medium-duty farming rather than intensive industrial uses.

TRANSMISSIONS OVERVIEW
The International Harvester 724 tractor features an 8-speed or 12-speed partial power shift transmission, allowing for smooth gear transitions and precise control over speed and torque, which is advantageous for various agricultural tasks. This transmission type enhances operational efficiency in varying field conditions but may require some operator training to optimize performance. In scenarios involving heavy load or changing terrain, the partial power shift helps maintain engine RPM and improve fuel efficiency.

TRANSMISSION 1
The International Harvester 724 features a partially synchronized transmission with a total of 8 forward and 4 reverse gears, allowing for versatile operational flexibility across various field conditions. The need to stop the tractor for range shifting can be a drawback in time-sensitive tasks, but the synchronization improves gear engagement, which enhances drive stability. This transmission design is ideal for tasks that require consistent speed and power, such as plowing or haymaking, yet may reduce efficiency in applications requiring frequent gear changes.

| Gears |
8 forward and 4 reverse |
| Description |
Four gears (1-4) in high, low, and reverse ranges. Gear shifting is synchronized using the clutch. Tractor must be stoppped to shift range. |

TRANSMISSION 2
The International Harvester 724 tractor features a partial power shift Agriomatic S transmission, offering 12 forward and 4 reverse gears, enhancing operational flexibility. The right-hand power shift lever allows for seamless transitions between high, low, and Agriomatic ranges, facilitating efficient speed adjustments for various field conditions. A potential challenge may arise in mastering the power shuttle function in reverse, which, while providing versatility, may require additional operator familiarity for optimal performance.

| Description |
The Agriomatic S provides an additional four forward speeds selected by a right-hand power shift lever. Pushing the lever forward engages the Agriomatic range, while rearward uses the conventional range. The Agriomatic speeds are between high and low ranges, so this provides an undershift in high range and an overshift in low range. In reverse range it operates as a power shuttle. |

MECHANICAL
The International Harvester 724 tractor features a robust 4x2 2WD or optional 4x4 MFWD configuration, providing versatility for varied terrain and task requirements. Its 8-speed/12-speed partial power shift transmission enhances operational efficiency by enabling smoother transitions between gears, although the manual steering can be challenging in tighter maneuvering situations. The open operator station offers good visibility and airflow but may lack comfort and protection against the elements compared to enclosed cabs.

INTERNATIONAL HARVESTER 724 TIRES
The International Harvester 724 tractor is equipped with two tire configurations, varying by 2WD or 4WD setup. The 2WD option with 7.50-16 front and 13.6-38 rear tires prioritizes agility and lower maintenance costs, making it suitable for lighter agricultural tasks on dry terrain. Conversely, the 4WD configuration with 11.2-24 front tires enhances traction and stability, ideal for challenging conditions such as muddy or hilly landscapes, but may incur higher operational costs and increased tire wear.
