TRANSMISSION 1
The John Deere 4930 features a Quad-Range transmission that offers 16 forward and 6 reverse gears, providing versatility across various field conditions and crop requirements. Its hydraulic wet disc clutch system enhances durability and control during gear changes, while the synchronized shift between gears 2-3 facilitates smoother transitions without needing to stop. However, the necessity to halt the tractor to shift ranges may limit operational efficiency in dynamic tasks requiring frequent gear changes.
| Transmission | Quad-Range |
| Type | partial power shift |
| Gears | 16 forward and 6 reverse |
| Clutch | hydraulic wet disc |
| Description | Four gears (1-4) in four ranges (A-D). Power shift between pairs 1-2 and 3-4 in each range, with synchronized shift between 2-3. Two reverses in ranges A-C. Tractor must be stopped, and clutch used, to shift ranges. Power shift is provided hy a hydraulically-controlled planetary that provides an under-drive to each gear |
