ENGINE OIL
The CaseIH 4994 tractor has an oil capacity of 27 quarts (25.6 liters), which is relatively moderate for its class, allowing for adequate lubrication and cooling under typical operational loads. Ensure regular oil changes to maintain optimal engine performance and longevity, as insufficient oil can lead to increased wear and potential engine failures. This oil capacity is advantageous for extended operation periods but requires careful monitoring of oil levels, especially in demanding agricultural tasks.

TRANSMISSION
The CaseIH 4994 features a full power shift transmission with 12 forward and 2 reverse gears, offering smooth transitions and efficient power management. A hydraulic wet disc clutch enhances durability and reduces maintenance needs, while the electronically-controlled system simplifies gear selection with a single lever. However, operators must be aware that shifting out of neutral requires movement in first gear, which may challenge new users in adapting to the specific operational protocol.
| Type | full power shift |
| Gears | 12 forward and 2 reverse |
| Clutch | hydraulic wet disc |
| Oil capacity | 63qts / 59.6L 59qts / 55.8L (without PTO) Case Powergard PTF |
| Description | Electronically-controlled Case power shift transmission operated with single control lever and inching pedal. The inching pedal must be depressed to move from park/neutral into first gear. Tractor must be moving in first gear before higher gears can be selected. Gear changes made by pushing control lever into upshift or downshift position. Control lever can be held in upshift/downshift position for multiple gear changes |
