ENGINES OVERVIEW
The International Harvester 606 tractor is equipped with three engine options: a 3.6L 6-cylinder gasoline engine, a 3.9L 6-cylinder diesel engine, and a 3.6L 6-cylinder LP gas engine, providing versatility for fuel selection based on operational needs. The gasoline variant offers a smoother operation for lighter tasks, while the diesel engine provides superior torque and fuel efficiency for heavy-duty applications, making it suitable for tilling and hauling. However, the choice of fuel may affect maintenance needs, with diesel engines generally requiring more rigorous servicing and potentially higher initial costs.

TRANSMISSIONS OVERVIEW
The International Harvester 606 tractor features a 10-speed transmission for enhanced versatility, allowing for precise speed adjustments across various terrains and applications. Its 5-speed variant offers simplicity and ease of use, ideal for operators who prioritize straightforward operation over complexity. Consider the operational needs and terrain types when selecting between the two to maximize efficiency and performance.
| Description |
10-speed/5-speed |
TRANSMISSION 1
The International Harvester 606 features a Torque Amplifier (TA) that enhances its versatility by offering a powershift from direct drive to lower speeds, which is advantageous for heavy-duty tasks requiring additional torque. With 10 forward and 2 reverse gears, including a high-speed option that increases first gear speed by 40%, this tractor can efficiently adapt to various field conditions and implements. However, the relatively limited oil capacity of 52 quarts may necessitate regular monitoring to prevent overheating during prolonged operations.
