How To Sharpen Lawn Mower Blades
A lawn mower blade should be aggressively sharp but not as precise as a razor's edge. A good basis for the sharpness of the lawn mower blade is that you can touch it with your hand without getting cut.
A lot of people have a misconception that razor-sharp lawn mower blades will cut the grass better. Unfortunately, blades that are too sharp tend to roll over the grass and chip the tips off, making the grass' edge look ragged.
Sharpening lawn mower blades is important, and you can do it either with a manual file or an electric grinder. Depending on the tool that you'd like to use, make sure that you don't over-sharpen your blades. Here's how you can do the task:
Sharpening Using a Manual File
- Remove the lawn mower blade according to your manual. Make sure to mark the blade's correct side so you can put it back in the right position after sharpening.
- Using a vise, clamp the lawn mower blade securely.
- Hold the mill file at the same cutting angle as the blade. Start by filing from the inside of the blade, moving towards the outside. Remember to keep following the blade's cutting edge.
- Make sure to smoothen out any rough spots or nicks on your blade. Your blade should be about as sharp as a butter knife's edge.
- After sharpening, make sure to use a blade balancer to check your lawn mower blade before putting it back.
Sharpening Using an Electric Grinder
- Follow your manual and remove the lawn mower blade properly from your machine. Make sure to mark your blade to ensure that you can put it back correctly after sharpening.
- Clamp the lawn mower blade securely using a vise. Prepare for sharpening by wearing the appropriate safety gear when using electric tools like the grinder.
- Before starting, hold your electric grinder against the lawn mower blade. Tip the grinder up and down until you feel that the disc is aligned with the angle of the blade.
- Hold your electric grinder at this angle and move it across the metal using light pressure. Make sure that you don't overheat the blade because it will cause the blade to become brittle. Do not grind away too much metal because it will cause the blade to become unbalanced.
- Make several passes on your blade with your grinder, occasionally checking for the sharpness. To remove the nicks from your blade, hold the grinder at a right angle and make a few passes until the nicks are gone.
- Balance your blade using a precision balancer. If one side tips lower over the other, make a few more passes until the blade passes the balance test. Put back the blade onto your machine, and you can now mow your lawn.
Mowing a lawn is hard, but it is the only way to keep the house looking neat and clean. Mowing the lawn can be made easy with perfectly sharpened lawn mower blades that not only makes the grass look greener but it makes the job a whole lot faster.
