ENGINES OVERVIEW
The International Harvester 460 tractor is equipped with a choice of three power units: a 3.6L 6-cylinder gasoline, a 3.9L 6-cylinder diesel, or a 3.6L 6-cylinder LP gas engine. The diesel variant offers better fuel efficiency and higher torque for heavier loads, making it ideal for farming tasks such as plowing and tilling. However, the gasoline and LP versions may provide easier starting in cold conditions, which is a consideration for operators in variable climates.

ENGINE OIL
The International Harvester 460 tractor has an oil capacity of 9 quarts (8.5 liters), which is essential for maintaining optimal engine performance and longevity. Regular oil changes are crucial due to the moderate oil capacity; using high-quality oil can enhance lubrication and overall efficiency. An advantage of this capacity is practical maintenance, allowing for easier oil checks and changes, but it may require more frequent top-ups if operating under heavy loads.
ENGINE DETAIL 3
The International Harvester 460, powered by the C-221 LP gas engine, offers a solid 61hp at a rated RPM of 1800, ideal for medium-duty agricultural tasks. Its 8.75:1 compression ratio combined with the 180 lb-ft torque at 1300 RPM provides efficient low-end power, advantageous for plowing and pulling applications. The oil bath air cleaner contributes to engine longevity, but the reliance on LP gas may limit fuel availability in certain areas, which is a consideration for operational logistics.

TRANSMISSIONS OVERVIEW
The International Harvester 460 tractor features a versatile 5-speed or optional 10-speed transmission, optimizing power delivery for various field operations. The 10-speed option enhances efficiency in different terrain types and load requirements, providing better control during tasks like plowing or hauling. However, potential challenges include a steeper learning curve for operators less familiar with multi-speed systems, which could impact productivity in the short term.
| Description |
