Want some recommendations on the way to do that? Well here are a number of them.
Before mowing your lawn, remove rocks and sticks which will get within the way. Doing this prevents the materials from getting hurled by the mower.
Keep your lawn healthy by not cutting the grass too short. Generally, leave half of an inch of grass sticking out of the ground. If you discover the activity of mowing your lawn as something therapeutic, try to not be overeager about it.
