Lawn Boy Lawn mower blades won't engage
If your Lawn Boy lawn mower blades won't engage, start with the PTO clutch, since that is the most common reason the deck blades will not turn. The PTO clutch connects engine power to the mower blade system, and if the clutch solenoid is not getting power or the clutch itself is worn out, the blades will not spin. The next likely cause is a bad PTO switch. A faulty mower PTO switch problem can keep power from reaching the clutch, so even if the clutch is still good, the riding mower blades not engaging symptom will remain. You can check the PTO switch with a multimeter for continuity, but the PTO clutch itself is not repairable and must be replaced if defective. On some models, related parts like the drive belt and blade engagement components can also matter, but the PTO clutch and PTO switch are the first places to look based on this Lawn Boy symptom. If you need the exact replacement PTO clutch, PTO switch, mower blade, or other Lawn Boy lawn mower parts, enter your model number on RepairClinic.com to find parts that fit your machine.
01 - Lawn Boy Lawn Mower PTO Clutch
The PTO (Power Take Off) clutch provides a means of manually disconnecting the engine from the blades. When the clutch solenoid is energized, the clutch engages the drive belt to drive the rotation of the lawn mower blades. If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it.

02 - Lawn Boy Lawn Mower PTO Switch
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.
