How to Properly Test the Riding Lawn Mower’s Safety Switch

To ensure your riding lawn mower operates safely, it’s crucial to regularly test the safety switch. I’ve found that a systematic approach works best when checking this component.

Firstly, I make sure the mower is on a flat surface and turned off. Then, I sit in the seat and turn the key to the ‘ON’ position without starting the engine.

Next, I engage the safety switch mechanism—often by lowering the cutting deck lever or engaging the parking brake—and then attempt to start the engine.

If the mower doesn’t start, that’s a good sign; it means the safety switch is functioning properly as it should prevent the engine from firing up under these conditions.

However, if the engine does start, I know there’s an issue with the safety switch. In this case, I take the time to inspect the switch connections for any corrosion, loose wires, or damage.

I always follow the manufacturer’s troubleshooting guide, which is specifically tailored to my mower’s model.

It’s better to address any issues immediately rather than risking an unsafe operation, and I never bypass the safety features for convenience. Safety always comes first in my book.

What are the Other Safety Switches + How to Bypass Them
