TRANSMISSIONS OVERVIEW
The International Harvester 523 tractor features an 8-speed/12-speed partial power shift transmission, allowing for smooth gear transitions and improved efficiency during operations. This transmission type enhances traction and performance across varying terrains, making it suitable for heavy-duty applications. However, operators may need to adapt to the learning curve associated with partial power shift systems for optimal performance.

TRANSMISSION 1
The International Harvester 523 tractor features an 8-speed forward and 4-speed reverse transmission, allowing for versatile speed settings suitable for various agricultural tasks. The 279.4mm dry disc clutch provides robust engagement, but may require more maintenance than wet systems, particularly in heavy-duty operations. With an oil capacity of 35.1 quarts, sufficient lubrication is crucial for optimal performance and longevity, especially in prolonged usage scenarios.

TRANSMISSION 2
The International Harvester 523 tractor features a partial power shift Agriomatic S transmission, which offers 12 forward and 4 reverse gears, enhancing operational flexibility. The ability to engage additional forward speeds allows for precise speed control, making it advantageous for varied agricultural tasks and terrain conditions. However, operators should be aware of the learning curve associated with mastering the power shift mechanism, especially when transitioning between ranges for efficient operation.

| 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 523 tractor offers versatile traction options with its 4x2 (2WD) and 4x4 (MFWD) configurations, providing adaptability for various terrains. Its mechanical rear differential lock enhances traction in challenging conditions, while the open operator station facilitates ease of access but may expose the operator to environmental elements. The availability of an 8-speed to 12-speed partial power shift transmission allows for precise speed management, making it well-suited for both fieldwork and transport tasks.
