How To Replace Mower Blades

If you're a homeowner with a lawn, chances are you have a lawn mower. Regular maintenance of your lawn mower is important to ensure it continues to run smoothly and efficiently, and one aspect of that maintenance is replacing the mower blades.

Why Replace Mower Blades?

Over time, mower blades can become dull and damaged from cutting through thick grass and hitting rocks or other hard objects in the lawn. A dull or damaged blade can cause an uneven cut, which can lead to an unhealthy lawn. Additionally, a damaged blade can put extra strain on the mower's engine, which can cause it to work harder and wear out faster.

When To Replace Mower Blades?

It's generally recommended to replace your mower blades at least once per mowing season, or every 20 to 25 hours of use. However, if you notice your mower is leaving behind uneven patches of grass or if the blades are visibly damaged or dull, it's time to replace them.

HOW TO REPLACE MOWER BLADES

Remove the old blade: Locate the blade mounting bolt, which holds the blade in place. Loosen the bolt with a wrench, being careful not to damage the blade/s or the bolt. Remove the old blade/s and set them aside.

 

Clean the area: Before installing the new blade, clean the area around the blade mounting bolt and the underside of the mower deck.
This will help prevent debris from getting stuck between the blade and the mower deck, which can cause damage.

 

Install the new blade: Carefully align the new blade with the blade mounting bolt and tighten the bolt with a wrench. Be sure not to overtighten the bolt, as this can damage the blade or the mower deck.

 

Test the mower: Reconnect the spark plug wire and test the mower to make sure the new blade is properly installed and functioning correctly.

 

Replacing your mower blades is an important aspect of lawn mower maintenance that can help ensure a healthy lawn and a properly functioning mower.
