As a homeowner with a lawn, it's likely you own a lawn mower. Consistent maintenance of your lawn mower is crucial to guarantee its continuous smooth and efficient operation. Among the essential aspects of this maintenance is the periodic replacement of the mower blades.

Why Replace Mower Blades?

Mower blades undergo wear and tear over time, becoming dull or damaged from cutting through dense grass and encountering rocks or hard objects in the lawn. A blade in such condition can result in an uneven cut, leading to an unhealthy lawn. Moreover, a damaged blade can strain the mower's engine, causing it to work harder and wear out faster.

When To Replace Mower Blades?

It is generally recommended to replace mower blades at least once per mowing season or every 20 to 25 hours of use. However, if you observe your mower leaving uneven patches of grass or notice visible damage or dullness in the blades, it's time for a replacement.


Before replacing mower blades, prioritize safety. Turn off the mower and disconnect the spark plug wire to prevent accidental startup. Wear gloves and safety goggles to safeguard your hands and eyes.

The Steps:
  1. Remove the old blade: Locate the blade mounting bolt holding the blade in place. Loosen the bolt with a wrench, taking care not to damage the blade or the bolt. Remove the old blade and set it aside.
  2. Clean the area: Before installing the new blade, clean the area around the blade mounting bolt and the underside of the mower deck. This prevents debris from getting lodged between the blade and the mower deck, potentially causing damage.
  3. Install the new blade: Align the new blade carefully with the blade mounting bolt and tighten the bolt using a wrench. Avoid overtightening to prevent damage to the blade or mower deck.
  4. Test the mower: Reconnect the spark plug wire and test the mower to ensure the new blade is correctly installed and functioning as intended.

Replacing mower blades is a crucial aspect of lawn mower maintenance, contributing to a healthy lawn and ensuring the proper functioning of the mower.
