Are Lawn Mower Blades Reverse Thread?

Lawn mower blades are a common source of confusion for many people. The main reason for this is because there are so many different types and sizes of lawn mowers on the market. Lawn mower blades are typically either right-handed or left-handed threads.

How Do You Know If Your Lawn Mower Blade is Reverse Thread?

If you’re unsure whether your lawn mower blade is reverse thread, there are a few things you can check. First, consult your mower’s owner’s manual. If the manufacturer does not specifically state that the blade is reverse thread, it likely isn’t.

You can also try unscrewing the blade with your hands. If it feels like the blade is tightening instead of loosening, it’s probably reverse thread. Finally, take a close look at the threads on the bolt that secures the blade to the mower deck.

If they appear to be running in the opposite direction from what you’d expect (i.e., clockwise instead of counterclockwise), then your lawn mower likely has a reverse-threaded blade.
