Most homeowners strive for beautiful yards, but neglecting a key component of lawn maintenance – the lawn mower itself – can lead to issues not only with your lawn but with the machine as well. Neglecting regular maintenance can result in uneven cuts, scalping and other issues that can damage your lawn. Regular maintenance also ensures your mower operates at peak efficiency, which can extend the lifespan of your mower, saving you money in the long run by preventing costly repairs or the need for a new machine. To unlock the full potential of your lawn mower, clean it after each use to prevent buildup of grass clippings and debris, and store it in a dry, sheltered place between uses. Change the Spark Plug: Remove the old spark plug using a spark plug wrench and replace it with a new one.
