ENGINE DETAIL
The Case 4994 tractor features a powerful Saab-Scania turbocharged 8-cylinder diesel engine with a displacement of 14.2L, providing 400hp at 2100 RPM and an impressive torque of 1140 lb-ft at 1300 RPM, ideal for heavy-duty applications such as plowing and tilling. Its dual paper air cleaner enhances filtration efficiency, while a relatively high compression ratio of 15.5:1 can improve fuel efficiency but may require higher-quality diesel fuel to prevent knocking. Maintenance will need to consider the coolant capacity of 88 quarts, and valve clearances are crucial for optimal performance, particularly under operational stress or load conditions.

TRANSMISSION
The Case 4994 tractor features an electronically-controlled full power shift transmission with 12 forward and 2 reverse gears, providing versatile operation for various field conditions. The unique inching pedal design allows for smooth transitions from park/neutral but requires the tractor to be in motion for higher gear engagement, which enhances control during low-speed operations but may challenge new operators. With a substantial oil capacity of 63 quarts (or 59.6L), the system ensures effective lubrication and cooling, critical for maintaining performance during prolonged use.

| Gears | 12 forward and 2 reverse |
| Oil capacity | 63qts / 59.6L 59qts / 55.8L (without PTO) Case Powergard PTF |
| Description | Electronically-controlled Case powershift 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 |
