You'll learn the 5 most important things you can do to extend the life of your mower, saving you money and time. We'll cover:

1. Changing the oil

2. Keeping blades sharp

3. Cleaning the deck

Whether you’re a weekend warrior or a seasoned lawn care pro, your lawn mower is a vital tool in keeping your yard looking its best. Just like any other machine, regular maintenance can extend its life, improve performance, and save you from costly repairs down the line.

1. Change the Oil Regularly

Just like your car, your mower’s engine needs clean oil to run efficiently. Dirty or old oil can cause the engine to overheat or wear down. For most gas-powered mowers, change the oil after every 25-50 hours of use or at the start of each mowing season. Always check the owner’s manual for specific recommendations and use the right type of oil.

2. Keep the Blade Sharp

A dull blade rips grass instead of cutting it cleanly, which can stress your lawn and make it more vulnerable to disease. Sharpen the blade at least once a season—or more frequently if you mow often or hit rocks and debris. If sharpening isn't your thing, most hardware stores or lawn care shops offer blade sharpening services.

3. Clean the Deck After Every Use

Grass clippings, dirt, and debris can accumulate under the mower deck, causing rust and reducing cutting efficiency. After mowing, take a few minutes to scrape or hose off the underside of the deck. If your mower has a wash-out port, use it to make cleaning easier.

4. Check the Air Filter

A clogged air filter restricts airflow to the engine, making it work harder and reducing performance. Clean foam filters with soapy water and replace paper filters as needed. This simple step can improve fuel efficiency and prolong engine life.

5. Inspect the Spark Plug and Fuel System

At the start of each season, check the spark plug for signs of wear or carbon buildup. Replacing it annually can help ensure a strong start every time. Also, use fresh gasoline and consider adding a fuel stabilizer if you're storing the mower for more than 30 days to prevent carburetor issues.

Final Thoughts

A little maintenance goes a long way. These five tips take just a few minutes each but can save you hours of frustration and hundreds in repairs. Treat your lawn mower well, and it’ll return the favor with years of reliable service—and a beautiful lawn to show for it.
