If your Murray lawn mower blades won't engage, the problem usually starts with the PTO clutch. The PTO clutch transfers engine power to the deck through the drive belt, so if the clutch is not getting power, the clutch solenoid has failed, or the clutch is simply worn out, the mower blades won't engage and the blades will not rotate. On many Murray riding mowers, the next most likely cause is a bad PTO switch. If the PTO switch is defective, it may not send power to the clutch, which leads to a mower PTO clutch not working even though the engine runs normally. A multimeter continuity test can help confirm whether the switch is the issue. Since the PTO clutch is not repairable, a failed clutch will need to be replaced. If your riding mower blades are not engaging or your riding mower deck blades will not turn, RepairClinic.com makes it easier to track down the fault and get the right replacement part fast.

The PTO switch provides power to the PTO clutch. If the switch is defective, it may not supply power to the PTO clutch. As a result, the clutch won’t engage, and the lawn mower blades won’t rotate. To determine if the switch is defective, use a multimeter to test it for continuity. If the PTO switch is defective, replace it.
