Operating your mower with a dull blade can be hard on your lawn, leaving the grass tattered or torn rather than cut. This will cause it to look yellow and restrict healthy growth. Also, a damaged blade can be a danger to the operator or nearby people.
Replacing the blade isn't difficult and is a task that anyone should be able to complete in 15-30 minutes. There are some things to keep in mind as you start this project though. You will be working with a sharp object (the blade), so using a pair of heavy-duty gloves, removing the battery, and carefully blocking the blade are important safety measures to keep in mind as you start your work.
Once you've completed the replacement, I recommend mowing your yard right away and experience the satisfaction of your crisply mowed lawn!
