TRANSMISSION 2
The International Harvester 806 features a two-range Torque Amplifier (TA) that significantly enhances its operational flexibility by allowing clutchless downshifting for each gear, facilitating smoother transitions under varying loads. With 16 forward and 8 reverse gears, the partial power shift transmission offers excellent versatility for diverse farming tasks, although mastering the TA operation may require additional training for optimal performance. This system is particularly advantageous in scenarios requiring quick adjustments in speed without losing momentum, such as during heavy towing or in challenging field conditions.
