ENGINE DETAIL
The International Harvester 485 features a robust D-179 diesel engine with a displacement of 2.9L and a gross power output of 53.6hp, making it suitable for moderate farm tasks and light agricultural work. Its direct injection fuel system enhances fuel efficiency and performance, particularly at the rated torque of 140.4lb-ft achieved at 1400 RPM, suitable for tasks requiring consistent pulling power. However, the design limits power output for large-scale applications, making it less ideal for high-demand operations but effective for smaller, localized farming activities.

TRANSMISSIONS OVERVIEW
The International Harvester 485 tractor features an 8-speed synchromesh transmission, allowing for smooth gear shifts and efficient handling in various field conditions. The optional 16-speed two-speed power shift enhances versatility, offering more precise control over speed and torque for tasks such as plowing or transporting loads. While the power shift system provides advantages in productivity, it may lead to increased repair complexity and maintenance requirements compared to simpler transmission systems.

TRANSMISSION 1
The International Harvester 485 tractor features a synchromesh transmission with 8 forward and 4 reverse gears, providing efficient power management across varying terrains. The two-range gear design enhances adaptability for both low-speed tasks, such as tilling, and high-speed applications, like transport. However, the complexity of the synchromesh system may require more maintenance and technical knowledge for optimal performance compared to simpler transmission types.
| Type | synchromesh |
| Gears | 8 forward and 4 reverse |
| Description | Four gears (1-4) in two ranges (low/high) plus reverse range |
TRANSMISSION 2
The International Harvester 485 tractor features a two-speed power shift transmission with a unique torque amplifier, enabling smooth gear transitions and enhanced control under varying load conditions. With 16 forward and 8 reverse gears, it offers versatility for a range of tasks, making it suitable for both fieldwork and transport. However, the complexity of the transmission may require specialized maintenance and understanding for optimal operation.
