How to Install a Mower Mulching Blade

The purpose of a mulching blade is to cut a blade of grass multiple times, turning the grass into tiny bits. These bits become a layer of mulch for the grass. After repeated use it becomes time to replace a mower mulching blade.

Mulch is excellent for a few reasons. Mulch is a weed suppressor, a moderator of soil temperature, a water retention device, and finally, it is organic.

Follow these steps to properly install a mower mulching blade.

1. Make sure you have taken the necessary protective measures, which include eye goggles and gloves.

2. Remove the spark plug wire from the spark plug.

3. Turn the lawn mower on its side. You need to prevent the blade from moving here. Some people put a wedge to hold the blade in place where as other people just hold it with their hand.

4. Remove the center nut by use of a socket wrench.

5. Slide the washer from the post and remove the blade from the post.

6. Place the new mulching blade on the post.

7. Loosely screw the nut back in place.

8. Hold the blade in place while tightening the nut with a torque wrench.

9. Tighten the nut to the load required which can easily be found with the mulching blade instructions. If you do not have the documentation visit the mulching blade makers website, which will potentially have the information you are seeking (I once had to do this).

10. Gently, turn the lawn mower back to its original position.

11. Place the spark plug in the lawn mower ejection shoot. This forces the grace to stay under the lawn mower while it is become mulch.

12. Reattach the spark plug wire to the spark plug.

13. Start up the lawn mower to confirm that the lawn mower is not making any strange noises or vibrating. If any of the above are happening, you need to go back to step 1 and repeat. If you tightened the nut to the correct load everything really should be fine.

14. Once the lawn mower is not making any strange noises or vibrations it is time for you to cut some grass. Cut a small patch of grass to ensure the mulch is working properly. None of the grass or mulch should come out of the chute. Instead, the mulch should stay under the lawn mower housing.
