| Clutch | dual 225mm wet disc Perma Clutch |
| Oil capacity | 52.8qts / 50.0L |
| Description | The PowrReverser transmission adds a left-hand shuttle lever to the SynchroPlus transmission. Reverse gear is replaced with a fourth gear in each range. Reverse speeds slightly higher than the matching forward speed |
TRANSMISSION 3
The John Deere 6630 features a PowrQuad transmission with 16 forward and reverse gears, providing a versatile range of operating speeds to match various field conditions. The dual wet disc Perma Clutch enhances durability and offers smoother gear transitions, although manually shifting between ranges may slow operations compared to fully automatic systems. The optional creeper gear significantly increases low-speed control, making it ideal for tasks requiring precision, such as tilling or planting at very slow speeds.
