A sharp lawn mower blade is essential for a beautiful, healthy lawn. Sharpening your mower blade is a surprisingly easy task you should do everyone to two months to keep your grass even and green. Here’s what you’ll need for this inexpensive project:
TOOLS & MATERIALS
- Metal File
- Wood Block
- Blade Balancer (Optional)
When taking on this DIY task to sharpen a lawn mower blade, be sure to equip yourself with the proper safety gear.
Disconnect power. Before beginning any part of this project, confirm your mower isn’t connected to a power source. Be sure to wear safety gloves and protective eye wear. If your mower is corded, make sure it’s unplugged. If it’s battery operated, remove the battery and set aside. If it’s gas powered, disconnect the spark plugs.
Remove lawn mower blade. Turn your mower on its side. Using a wrench, remove the screw holding the blade in place. If the blade keeps turning while you work, try wedging a piece of wood next to it for leverage.
Sharpen blade. Securely clamp your lawn mower blade to a stable surface. Using a metal file or grindstone, follow the angle of the existing edge and sharpen at a 45-degree angle, evening out any rough edges.
Reinstall blade. Your blade needs to be properly balanced for your mower to run smoothly. Check the balance by spinning it, evening out any rough spots. Reinstall the blade, securing it tightly to the mower deck with its original screw. Your project is complete.
