Tools You’ll Need:
· Wrench
· Grinder
Step1
If you are using a walk behind lawn mower, then you'll need to turn the entire lawnmower on its side so that you can access the nut holding the blade on. Be sure not to turn the Lawn Mower onto its side too far so you don't leak any oil or fuel onto the ground. You will want to find the correct size wrench to loosen and remove the nut holding the blade. After you loosened the blade it will be free and can be removed. You should always note which side of the blade is on top before removing.
Step2
If you are using a riding lawnmower then you might need to remove the mower deck from the tractor. This will allow access to the blades. If you don't want to remove the deck then you will need to use a jack to jack the mower up so the blades can be accessed. Using a wrench, you can remove all the nuts that hold the blades onto the spindles. Next Remove blades. Note which side of the blade is on top before removing.
Step3
Examine blades. Look for excessive wear & tear in the blades. If the mower blades are extremely bad, you may need to purchase new blades. If your blades are in pretty good shape, only dull then you are ready for the next step.
Step4
Take your blades to your grinder. A small one will work just fine for this job. A handheld grinder works better than a table mounted grinder for most homeowner applications. This is because homeowner table grinders are not usually set up with a guide for lawn mower blades. Turn grinder on. Always be sure to wear the proper protective equipment and always consult owners manuals before using any
