Case IH DX18E–DX25E, MWX154S/160S Common Problems This Manual Covers
Case IH DX18E with MWX154S mower deck exhibits heavy vibration and sudden loss of blade drive. p. 125
Inspect the driveline universal joints for wear or seizing. Rebuild the driveline as necessary according to the troubleshooting procedures on page 125. Check the mower blades for interference with grass buildup and verify the deck cutting width matches the 1372 mm (54 in) specification.
Manual Section: MWX154S, MWX160S Mower DeckEngine RPM drops significantly and mower deck heavily loads the tractor when engaging the PTO. p. 74
Inspect the fan belt tension midway between the pulleys. Adjust the alternator position until the belt deflection measures 10 - 15 mm (7/16 - 9/16 in) as shown on page 74. Clear any excessive grass buildup from under the deck and verify ground speed is appropriate.
Manual Section: Lubrication and MaintenanceTractor hydraulic and engine systems overheating during continuous mowing sessions and triggering the safety shutdown. p. 133
Drain and flush the cooling system, then refill with exactly 3.5 L (3.7 US qts.) of approved coolant mixture. Inspect the radiator cap and verify it holds 0.9 bar (13.1 PSI) of pressure as listed on page 133. Clean all debris from the hydraulic cooler.
Manual Section: SpecificationHydraulic power lift operates slowly and transmission slips under load while operating the mower deck. p. 70
Check the rear axle and transmission oil dipstick. Drain the old fluid and fill the system with 13 L (13.8 US qts.) of clean hydraulic oil as specified on page 70. Replace the hydraulic system oil filter and verify the two-spool control valve operates smoothly.
Manual Section: Lubrication and MaintenanceFrequently Asked Questions
What are the torque specs for the main bolt on Case IH MWX160S mower deck?
For the MWX160S mower deck, the blade retaining bolt should be torqued to 98 – 118 N⋅m (72 – 87 ft-lb) during installation. It is important to recheck and re-torque these fasteners after the first hour of mower operation, and daily thereafter, to ensure proper security and prevent damage.
