How to Keep Lawn Mower Blades Sharp

Keeping you mow blades sharp is a crucial aspect of cutting grass. By putting in the time and doing regular blade maintenance you can keep your lawn mower cutting like the day you bought it. Before jumping into the actual review ToolShelf would like to point out a few key points to keep your mower blades sharp.

Preventing Dull Blades

Many things can potentially dull your blade, and fast. Before mowing your lawn always do a routine check for rocks, big sticks, toys, and any other foreign objects that might damage the blades. Also mow your lawn when its dry and not wet. Wet grass will not only stress the grass but will also cause your blades to dull much quicker.

How to Identify a Dull Blade

After you mow the lawn a good way to check if you have a dull blade or not is to look at the grass. If your cuts don’t look clean, there is a good chance your blades could use sharpening or replacing. Keeping a clean blade not only makes cuting grass easier but again it will ensure a much healthier lawn.

How to Sharpen a Dull Blade

Sharpening your blades twice a season is a good benchmark to keeping your blades sharp. Safety is very important so always shut down the lawn mower before attempting to sharpen the blades. Once the machine is safe for work, remove the blade, clean it off and sharpen it. A easy way to sharpen the blade is to put it in a vice to hold it down, then sharpen both sides with a file. For more details on sharpening lawn mower blades with a file, you can check out the video at the bottom of the post.

A great alternative to using the file is to purchase a blade sharpening bit. However, it requires a Proper drill and without one, this is simply not an option. If you do own a drill this is not only a fast and easy alternative, but it also guarantees the blade is being sharpened at a proper angle.
