Frequently Asked Questions (FAQs)

1. How do I know if my clutch is bad on my riding mower?

If the clutch is damaged, you may hear it slipping while it tries to engage, or you might hear your PTO engage and then stop right away, as it is designed for the fuse to fail first if it cannot turn the clutch.

2. Are all PTO clutches the same?

PTO clutches are designed to run in one direction only. Two clutches that look alike may be mounted on the engine differently. When the pulley is closest to the engine, or if the pulley is mounted away from the engine, the internal clutch rotation changes.

3. Should mower clutch spin freely?

Yes, the clutch pulley should turn freely when not engaged. It may have an electrical issue as well as bearing issue causing it to stall with no load and vibrate under a load.

4. How do you check an electric clutch on a lawn mower?

Start the engine and let it warm up. Activate the lever to engage the clutch. From a distance, look underneath the deck and check for mower blade operation. If you hear a squealing noise, shut the engine off and remove the ignition key.
