Neat Hack: My Grandpa’s Effortless Trick for Sharpening Lawn Mower Blades

Why Sharp Lawn Mower Blades Matter More Than You Think

Before we get to the trick, it’s important to understand why blade sharpness matters so much.

Sharp Blades vs. Dull Blades

A sharp blade:

• Cuts grass cleanly
• Promotes healthier lawns
• Reduces stress on the mower
• Uses less fuel or electricity
• Prevents disease in grass

A dull blade:

• Tears grass instead of cutting it
• Causes browning at the tips
• Makes lawns vulnerable to pests and disease
• Forces the engine to work harder

My grandpa used to say:

“A mower doesn’t need to be powerful—it needs to be sharp.”
