| Type | partially synchronized |
| Gears | 12 forward and 3 reverse |
| Clutch | hydraulic wet disc |
| Description | Three speeds (1-3) in four ranges (A-D). Synchronized shifting between speeds |
TRANSMISSION 2
The John Deere 8760 features the PowrSync transmission, offering 24 forward and 6 reverse gears, which ensures versatility in various field operations and transport applications. The hydraulic wet disc clutch enhances durability and provides smooth engagement, reducing operational wear. However, while the partial power shift allows for efficient power management, it may require additional driver skill to optimize gear selection during demanding tasks.
