My Riding Lawn Mower Blades Won't Engage

The main indication of a lawn mower blade not turning is when you've made a few passes on the riding mower, but you can't smell any fresh cut grass. Something is clearly wrong. The best feature of zero turn mowers is that you can disengage the blades going over curbs and other things you don't want to cut. But when your riding mower blades won't spin, you might as well be driving a forklift or a dune buggy. So, what's the answer for fixing mower blades that won't engage? Repair Clinic is here to help you regain your neighborhood title as Lord of Lawn Care. We'll help you diagnose the problem, sell you the right parts for your model, and show you how to install them. Then, you'll henceforth be known as the DIY Lord of Lawn Care.

Common solutions for: Lawn mower blades won't engage
Solution 1:
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.

Solution 2:
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.
