TRANSMISSION 4
The John Deere 4430 with a Syncro-Range Creeper transmission offers 13 forward and 4 reverse speeds, enhancing versatility for various tasks, particularly in tight spaces or when precision is required. The optional creeper range provides additional gearing options within the first five gears, which can be advantageous for operations like planting or tilling at low speeds. However, the interlock mechanism limiting shifts into higher gears while engaged must be considered, as it may restrict speed changes during operations needing quick adjustments.
| Transmission | Syncro-Range Creeper |
| Type | creeper |
| Gears | 13 forward and 4 reverse |
| Description | Optional creeper range adds additional speeds to the first five gears of the Syncro-Range transmission. An interlock prevents shifting into gears 6 through 8 while the creeper is engaged |
