Case IH Farmall 75U–115U Common Problems This Manual Covers
Case IH Farmall hydraulic system warning light activates, implements stop responding mid-field p. 271
Check hydraulic fluid level in the sight glass (between MIN and MAX marks) and inspect the filter for clogging. When replacing the filter, tighten only 3/4 turn by hand after contact. If fluid is low, top up to 60 liters (15.85 US gal) with Power Shuttle. Run through the fault checklist on page 271 before calling your dealer.
Manual Section: Hydraulic System TroubleshootingEngine high-temperature warning light flashes red, tractor loses power and shuts down p. 44
Stop the tractor immediately and shut down the engine when the red temperature warning activates. Let it cool before checking coolant level; the system holds 16 liters (4.22 US gal) with cab. Inspect radiator fins for packed debris and verify the cap seats fully. If the cause isn't obvious, contact your authorized dealer (page 44).
Manual Section: Engine TroubleshootingTransmission fault code shows on display, gears won't engage smoothly under load p. 114
Record the fault code number from the instrument panel display (pages 114, 261) and check the error code reference. Verify the operator seat switch is engaged (pages 62, 114) and the handbrake is fully released (pages 43, 261) before shifting. Check clutch pedal travel: 162 mm (6.3779 in.) from the cab platform (page 210). If the code returns after these checks, contact your dealer for calibration (pages 257, 259).
Manual Section: General Information, Controls and InstrumentsSteering wheel requires excessive force to turn, front axle feels stiff or jerky p. 181
Inspect hydraulic fluid level first; the steering system draws from the main reservoir. Check front tire pressure and look for visible damage to the steering linkage. If the problem started after rough terrain or an impact, verify the axle turning stop clearance is at 20 mm (0.79 in.) per page 181. Contact your dealer if stiffness continues.
Manual Section: Field OperationBattery charge warning light stays on after startup, alternator output reading incorrectly p. 294
Check battery terminals for corrosion and ensure both connections are tight. Inspect the alternator drive belt for cracks or slipping. This tractor runs a 12 V electrical system with a 120 A alternator (page 294). If the charge warning stays on after the engine runs above idle for several minutes, contact your dealer for a charging system test.
