The blades of your lawn mower are one of the most important parts. If they are dull, it will be hard for them to cut grass, and you will have to push harder on the machine. This means that your blade can quickly become damaged or break off entirely with regular use. How do you know when it is time to sharpen your blades? How do you go about sharpening them? We’ll answer these questions and more in this blog post!

Find out what type of mower blade you have

The blades are one of the more important parts of your mower, as they’ll give you a good cut each time.

A blade should be replaced if there is any sign that it’s been worn down or damaged by weathering; however, don’t forget about rotating them every couple of months so its effectiveness doesn’t decrease too much!

Blade types include: regular, mulching, high lift, and zero turning.

Get the right equipment for sharpening blades

The right equipment will greatly increase your chances of successfully sharpening the blades.

Tools you’ll need:

  • Screwdriver (flathead)
  • Bolt cutter or hacksaw
  • Angle grinder and metal grinding wheel (or a bench grinder if it is not too big)

Sharpen the blade, making sure to follow all safety precautions

The blade must be held securely in place, and you should always wear protective equipment when sharpening the lawn mower blades.

  • With a flathead screwdriver or wrench remove the bolt that secures the blade to its mounting bracket. Be careful not to damage any other parts on your machine.
  • Use a hacksaw or angle grinder to carefully cut off the metal of the blade.
  • Use a bench grinder or an angle grinder with a metal grinding wheel (such as aluminum oxide) to grind down the blade until it is at its original sharpness and shape.
  • Make sure that you do not overheat your blades when they are in use.
  • Repeat the previous three steps on the other blades until they are all sharp and ready for use.

Use a metal file to sharpen the edges and remove any burrs or nicks from the blade

  • Use a metal file to sharpen the edges and remove any burrs or nicks from the blade.
  • How often you need to do this really depends on how much your lawn mower is used, but it should be done at least once every six months if possible. You can also ask around in your area for recommendations for a good blade sharpener.

Test your work by running your finger along each side of the blade – if it feels rough, continue filing until it’s smooth

A good knife has a smooth blade that can be honed to reveal any imperfections. This is done by running your finger along the length of it – if you feel rough spots, continue filing away until they’re gone!

The blade should feel smooth to the touch, and you may need to file it more than once until this is achieved.
