I want to teach my son the safest way to clean out the clumps of grass under the lawnmower. I remember a neighbor getting very inured when he tried, probably because he did not turn off the lawn mower. Dumb move.
I turned it off and put it on it's side. However, I did not know the proper procedure to SAFELY and EFFECTIVELY clean out the clumps of grass. Also, is it a good idea to disconnect the spark plug while doing this?
