How to Remove a Lawnmower Blade


While cutting your lawn, you may notice at the end of the season that your mower does not seem to be cutting grass as well as it used to. If you have cleaned grass out from under the lawn mower and excess debris from the blade and it still will not cut properly, you may need to sharpen or the blade. To do this, you will need to remove the blade from the lawn mower. This is not a time-consuming task, and can be done in under an hour.

Step 1

Tilt the mower over with the dipstick of the oil well down and the air filter up. If your mower has a foam filter, you will need to tilt the mower with the air filter down after removing the gas from the engine.

Step 2

Take the spark plug wire out so that the engine does not start while you are working on it. Tuck it away so that the wire does not fall onto the spark plug.

Step 3

Attach a clamp to the deck of the mower to keep the blade from moving as you are loosening it.

Step 4

Loosen the bolt that holds the blade under the mower with a wrench. Squeeze the blade toward the wrench to loosen the bolt, then turn the bolt freely.

Tips and Warnings

  • Always tilt your mower in the correct direction. Tilting it the wrong way can cause oil to enter the air filter, or worse, fuel to enter the carburetor.
