Step-by-Step Guide on How to Sharpen Lawn Mower Blades
Now that you know why it is important to sharpen your lawn mower blades and when to do it, let’s go over the steps on how to sharpen them.
Before starting, make sure to turn off the lawn mower and unplug the spark plug to avoid accidental start-up.
Remove the Blades
To access the blades, you need to remove them from the mower. Depending on the type of mower you have, you may need to turn the mower on its side or remove a protective cover to access the blades. Make sure to follow the instructions in your mower’s manual.
Clean the Blades
Once you have removed the blades, clean them thoroughly with a stiff brush and soapy water. This will remove any dirt and debris that has accumulated on them.
Inspect the Blades
Check the blades for any cracks, chips or other damages. If the blades are severely damaged, it may be best to replace them instead of sharpening them.
Sharpen the Blades
You can sharpen the blades using a file or a grinding wheel. If you are using a file, start at the edge of the blade and file it at a 45-degree angle. Make sure to file evenly across the entire blade. If you are using a grinding wheel, follow the instructions in your mower’s manual and use protective gear.
Balance the Blades
After sharpening the blades, make sure to balance them. You can do this by hanging the blade on a nail or a piece of wire. If one end is heavier than the other, you may need to remove some metal from the heavier end to achieve a balance.
Reinstall the Blades
Once the blades are sharpened and balanced, reinstall them on the lawn mower. Make sure to follow the instructions in your mower’s manual and tighten the bolts securely.
