TRANSMISSION
The CaseIH 4894 features a partial power shift transmission providing 12 forward and 4 reverse speeds, optimizing operational efficiency across varied field conditions. The hydraulic wet disc clutch enhances durability and reduces slippage during heavy loads, but may require thorough maintenance to ensure optimal performance. Ideal for tasks requiring precise speed control, such as tilling or transporting heavy loads, the dashboard-mounted shift levers facilitate straightforward operation but may pose a challenge for operators new to H-pattern shifting.
| Type | partial power shift |
| Gears | 12 forward and 4 reverse |
| Clutch | hydraulic wet disc |
| Description | Four ranges (1-4) with three power shift gears (1-3) plus reverse in each range. Both shift levers mounted on the dashboard. Range shift lever is to the left in a H-pattern. Gear shift is an inline pattern on the right. |
