Maintaining your lawn mower ensures optimal performance and longevity. Regularly clean the mower after each use, removing grass and debris from the deck and blades. Sharpen the mower blades at least once a season for a clean cut. Change the oil and replace the air filter as recommended by the manufacturer. Check and tighten bolts and fasteners, and keep the tires properly inflated. Store the mower in a dry, sheltered area. Conduct an annual tune-up, including spark plug replacement and carburetor cleaning. Adhering to these practices not only extends your mower’s lifespan but also guarantees efficient and effective grass cutting.
