Proper maintenance is essential to ensure that your lawn mower runs efficiently and lasts for many years. Regular upkeep will help prevent costly repairs and keep your lawn looking pristine.

1. Clean the Deck

Grass clippings and dirt can accumulate underneath the lawn mower deck, affecting the mower's performance. After each use, clean the deck to prevent build-up.

How to clean:

Turn off the lawn mower and disconnect the spark plug (for gas lawn mowers).

Use a hose or a scraper to remove debris from the deck. For stubborn build-up, a wire brush can help.

Consider using a deck wash system (if available) to make cleaning easier.

2. Change the Oil Regularly 

If you have a gas-powered lawn mower, changing the oil is crucial for engine longevity. Old or dirty oil can cause engine wear and poor performance.

How to change the oil:

Warm up the engine for a few minutes to allow the oil to drain more easily.

Tilt the mower to drain the oil (if required) into a container.

Refill the lawn mower with fresh oil, following the manufacturer's recommendations.

3. Sharpen the Blades

Sharp blades are essential for a clean, even cut. Dull blades tear the grass rather than cutting it, leading to uneven growth and a less healthy lawn. Sharpen the blades every 1-2 months, or more often if you mow frequently.

How to sharpen blades:

Disconnect the spark plug (for gas lawn mowers).

Use a wrench to remove the blade and use a sharpening tool or file to sharpen the edges.

Reinstall the blade securely, making sure it is balanced to avoid damaging the mower.

4. Check the Air Filter

A clogged air filter can reduce engine performance and increase fuel consumption. For gas lawn mowers, check and clean or replace the air filter at least once a season.

How to clean/replace the air filter:

Remove the air filter cover.

Inspect the filter; if it’s dirty, clean it with compressed air or replace it with a new one if it's too worn.

5. Change the Spark Plug

A faulty or worn-out spark plug can cause starting problems and poor engine performance. Inspect the spark plug annually and replace it if necessary.

How to replace the spark plug:

Disconnect the spark plug wire.

Use a spark plug wrench to remove the old spark plug.

Install a new spark plug, ensuring it’s the correct type and gap size as recommended by the manufacturer.

6. Lubricate Moving Parts

Many lawn mowers have moving parts that benefit from occasional lubrication, such as the wheels, handles, and axles. Lubricating these parts reduces friction, extends the life of the mower, and ensures smooth operation.

How to lubricate:

Use a suitable lubricant for the mower’s moving parts (e.g., wheels and cable mechanisms).

Apply a small amount of lubricant and wipe off excess to prevent dirt from sticking.

7. Check Tires and Adjust Tire Pressure

For self-propelled lawn mowers, it’s essential to check tire pressure regularly. Low tire pressure can affect performance and cause uneven mowing.

How to check and adjust tire pressure:

Use a tire pressure gauge to check each tire’s pressure.

Inflate or deflate tires according to the manufacturer’s recommended PSI (pounds per square inch).

Conclusion

Maintaining your lawn mower properly ensures it performs optimally and lasts longer. By selecting the right mower for your lawn size and terrain and following these maintenance tips, you'll keep your lawn mower running smoothly, reduce repair costs, and enjoy a beautiful lawn year-round.
