Case IH SPX4410, Patriot Sprayer Common Problems This Manual Covers
Case IH SPX4410 boom swings wildly or flies back uncontrollably immediately after manual forward movement
Inspect the main valve block's floating hexagonal orifices for rounded edges where the set screw seats. A worn hex lets the screw back out and the orifice rotate 90 degrees, jamming the function. Replace the orifice with a square edged fitting and confirm the pressure compensated pump holds 2750 psi (page 256) before retesting.
Manual Section: Hydraulic System DiagnosticsSprayer fails to build pressure or pressure drops inconsistent with system monitor reading p. 285
Check the suction line strainer and boom strainers first; a restricted strainer starves the pump before working pressure ever develops. Verify the product pump circuit relief valve holds 2500 psi on page 255, then confirm the boom pressure switch closes at 14 p.s.i. on page 285 once flow resumes. Clean strainers daily under heavy product use.
Manual Section: Spray System DiagnosticsSprayer starts spraying then abruptly shuts off around 20 meters of boom width
Locate the isolated kill switch in the battery box and verify it sits fully seated; a partially tripped switch cuts power to the control node mid pass. Check nozzle size against the rate controller's flow limit. If output also drops, test the boom pressure switch circuit, which should close at 14 p.s.i. per page 285, and clean inline filters.
Manual Section: SPX Application Electrical System Quick Reference to TroubleshootingUniversal Terminal or spray screen does not appear on the display, machine won't initialize
Verify the master power switch is on before chasing a controller fault; the display can't initialize without it energizing the control node. Confirm system voltage reads near 14 volts at the battery, matching the alternator output spec on page 225, then check the fuse feeding Product Control Node 2 and replace it if open before reseating connectors.
Manual Section: Controller System Troubleshooting GuidePump draws hard on the starter while cranking and slows noticeably near 2500 psi p. 276
Tee a gauge into the hydrostatic charge circuit; it should read 360 to 380 psig per the technical specifications on page 276. Charge pressure below that range points to internal pump leakage or cavitation, forcing the engine to labor against load while cranking. Inspect suction lines for collapsed hose or air leaks and clean strainers before retesting.
Manual Section: Hydraulic System DiagnosticsEngine cranks slowly or won't start at all during cold winter mornings p. 57
Work through the fuel injection troubleshooting chart on page 57 for cold start conditions before condemning the starter. Confirm the battery still meets its rated 950 CCA at 0°F (-17°C) per page 208, since cranking amps fall off fast in the cold. Drain the primary fuel filter if water or gelled fuel shows up in the bowl.

How to reset error code on Case IH SPX4410
To clear error codes on the Case IH SPX4410, hold the DIAG key for 5 seconds to display the codes. Then, press and hold the increase and decrease keys simultaneously for 5 seconds to erase them. Finally, press the PROG key and use the Increase or Decrease key to scroll to EXIT to return to the Hourmeter display.
Torque specs for final drive on Case IH SPX4410
For the C014 Main Assembly, which is part of the final drive, the mounting adapter bolts (14) should be tightened to 12 ft-lbs. This is done after gradually tightening the countersunk bolts to ensure even pressure on the Belleville Spring.
What are the common error codes for Case IH SPX4410
Common error codes for the Case IH SPX4410 include ICU Error Code 1015 for a stuck seat switch, and 3020 if GOV engine speed data is "ERROR" or "NOT AVAILABLE". CNH Engine Fault Codes include 146 for Coolant Temperature Sensor Circuit issues and 155 for Intake Manifold Air Temperature Sensor Circuit problems.
How to reset ECU on Case IH SPX4410
To reset the ECU (SX Controller calibration settings) on the SPX4410, first remove power by turning the ignition key "off". Unplug the FNR position sensor and maximum speed sensor (or J46 connector). Turn the ignition key "on" with the park brake off. After both error codes flash, turn power off, reconnect sensors, and the controller will be ready to accept new calibration constants.
