John Deere HPX Series Common Problems This Manual Covers
John Deere HPX 4X4 Gas engine runs poorly, stalls under heavy load, or fails to start completely.
Test the fuel delivery system as outlined on page 27. Disconnect the fuel line and verify minimum flow is 105 ml (3.5 oz) in 15 seconds. Check the fuel pump minimum pressure is 10 kPa (1.5 psi). Replace the pump if values fall below specifications.
Manual Section: Engine - Gas Troubleshooting p. 32Engine cranks hard, runs rough at idle, or experiences constant misfires during normal machine operation.
Inspect the ignition system components starting on page 32. Remove and inspect spark plugs for heavy carbon fouling. Set the spark plug gap to 0.80 mm (0.031 in.) using a feeler gauge as specified on page 27. Reinstall the plugs and tighten securely.
Manual Section: Engine - Gas Troubleshooting p. 32Gears grind heavily during shifting and shift lever frequently disengages while driving under a heavy load.
Inspect the shift linkage and shift cable for wear. Verify the transaxle shift adjustment is centered in the Neutral position as directed on page 465. Adjust the accelerator pedal free travel to 2-6 mm (0.080 - 0.240 in.) per page 40 to ensure proper engagement.
