Part of the Case IH Operator Manuals.
All 133 pages of this Case IH Maxxfarm 40 Operator Manual (OEM #52105404) cover one machine and one job: keeping your tractor running right, day after day. Inside, you get a full safety section covering cold-weather starts, implement connection, and fuel handling, plus a detailed instrument panel walkthrough for every switch and lever: HST forward/reverse pedal, cruise control, PTO engagement, and differential lock. The hydraulic system diagram shows complete fluid routing for your lift and remote circuits. When the warning light blinks, the maintenance chart tells you exactly what interval you missed. Set the 36 L fuel tank above reserve, confirm the 7.0 L engine sump, and top the 43 L transmission before any field run. No more guessing which fluid goes where. Jump to any section by keyword or bookmark, pull it up on your tablet, and get back to work.

Case IH MAXXFARM 40, MAXXFARM 50 Common Problems This Manual Covers
Case IH Maxxfarm engine cranks but won't start or starts then stalls immediately p. 123
Check fuel level in the 36 L (9.5 U.S.gal.) tank first. Verify the key switch is in the correct start position and the shuttle lever is in neutral. In cold conditions, confirm the cold start aid indicator is ON before cranking. If the engine fires then dies, inspect the fuel sediment bowl for water or debris. See the engine troubleshooting guide starting on page 123.
Manual Section: Engine TroubleshootingOil pressure warning indicator stays on after engine reaches operating temperature p. 90
Stop the engine immediately and check oil level. The engine holds 7.0 L (1.9 U.S.gal.) of oil; top off if below the MIN mark on the dipstick. Verify the oil filler cap is sealed. If the light stays on with correct oil level, do not continue operating. Review the warning indicator reference in the maintenance section on page 90 before resuming work.
Manual Section: Lubrication and MaintenanceClutch pedal feels soft, slips under load, or does not fully disengage when pressed p. 124
Measure clutch pedal free play at the pedal pad. Correct play is 20–30 mm (0.79–1.18 in.) as specified on page 103. If play is outside this range, adjust per the clutch troubleshooting guide on page 124. Check transmission oil level on page 95; the system holds 43 L (11.4 U.S.gal.) and low fluid can affect clutch feel.
Manual Section: Clutch TroubleshootingTractor pulls to one side when braking, or brake pedal sinks to floor without stopping p. 125
Check brake pedal free play on both pedals: correct range is 50–60 mm (1.97–2.36 in.) per page 105. Unequal play between left and right pedals is the most common cause of one-sided braking. Verify transmission oil level (43 L / 11.4 U.S.gal.) is within range. Refer to brake system troubleshooting on page 125 for a step-by-step check of pedal return and linkage condition.
Manual Section: Brake System TroubleshootingThree-point hitch linkage won't raise implements or drops under load during operation p. 125
Verify hydraulic oil level is between MIN and MAX marks on the sight glass; the transmission and hydraulic system share 43 L (11.4 U.S.gal.) of fluid per page 95. Check that the hydraulic lift control lever is fully engaged and not in the float position. Listen for the relief valve sounding off, which indicates the system is working but overloaded. For full symptom mapping, see hydraulic lift system troubleshooting on page 125.
Manual Section: Hydraulic Lift System TroubleshootingSteering wheel requires heavy effort to turn or feels jerky and unresponsive at low speed p. 126
Check transmission oil level first; the hydraulic steering circuit draws from the shared 43 L (11.4 U.S.gal.) reservoir on page 95. Inspect the hydraulic schematic on page 58 to locate the steering circuit components. Confirm the engine is at operating RPM before making steering inputs; steering assist is engine-driven and will be stiff at idle. See steering system troubleshooting on page 126 for hard-steer and abnormal noise conditions.
Manual Section: Steering System TroubleshootingFrequently Asked Questions
How to reset transmission on CASE IH MAXXFARM 40 after fault?
If the HST transmission oil temperature is too high, the solution is to stop the engine to cool the oil, and then restart the engine. This action effectively resets the system after this specific fault.
