In the heat of summer, nothing beats the fresh look of a well-kept lawn. But keeping your grass lush and healthy doesn’t just happen by accident—it takes regular mowing (before those blades shoot up to six inches tall!) and, most importantly, a lawn mower that’s in top shape.

Think of your mower as the foundation of your yard care routine. If it’s not functioning properly, your yard will show it. That’s why we’ve put together these essential lawn mower maintenance tips to help you prep your machine for a flawless mowing season. Let’s get started!

Prep Like a Pro: Safety First!

Before diving into lawn mower maintenance, let’s ensure you stay safe and set up for success.

  1. First, unplug the spark plug: Your mower’s blades are sharp and powerful, so disconnecting the spark plug first ensures your mower won’t accidentally fire up while you’re working on it.
  2. Consult the owner’s manual: Different mowers have different maintenance needs. Refer to your unit’s manual for specific guidelines on oil type, blade sharpening intervals, and other key details.
  3. Wear protective gear: Gloves and safety glasses protect your hands and eyes from debris, and sturdy shoes prevent slips and injuries.

Taking these precautions ensures a safer, smoother maintenance process.

Check the Engine Oil

Just like you wouldn’t drive your car with low oil, your lawn mower needs proper lubrication to run smoothly. Here’s how to check it in a few simple steps:

  1. Cool down and level up: Park your mower on a flat surface and let the engine cool for a few minutes (hot oil \= messy readings!).
  2. The dipstick test: Remove the dipstick, clean it with a rag or paper towel, and then reinsert it completely.
  3. Read the magic marks: Pull it out again and check where the oil line lands. Ideally, it should be near the upper mark—if it’s at or below the lower mark, it’s time for a top-up!
  4. Top it off (if needed): Add a little oil at a time (check your manual for the right type) until you hit the sweet spot.

Pro Tip: Overfilling is just as bad as running low, so don’t go overboard!

Keep Your Mower’s Air Filter Clean

A clogged or dirty air filter can choke your mower’s performance, making it work harder (and wear out faster).

Before you fire up your mower this season, take a quick peek at the air filter. Here’s what to do:

  • Paper filter: If it’s dirty but intact, blast it with compressed air (from the inside out to dislodge debris). If it’s torn or falling apart, swap it for a new one—no questions asked.
  • Foam filter: Wash it gently with soapy water, rinse it, and let it dry completely. Then, add a few drops of clean motor oil (like moisturizer for your mower!) and squeeze out the excess before putting it back.

A clean filter ensures better airflow, a happier engine, and a smoother cut—so don’t skip this quick check!

Lastly, Check the Blade

The blade is one of the most critical parts of your lawn mower—keeping it in good condition ensures a clean, even cut. Since checking it can be risky, always follow the steps in your mower’s manual. Here’s what to watch for:

  • Dull blade: A dull blade tears grass instead of cutting it cleanly, leaving your lawn looking ragged. If sharpening isn’t your thing, your local dealer can handle it for you.
  • Bent, cracked, or worn out: Time for a replacement. A damaged blade isn’t just bad for your lawn—it can be dangerous.

A quick blade check now means a healthier, happier lawn later!

Final Thoughts

Keeping your lawn mower in top shape means a greener, happier lawn and fewer expensive fixes down the road. With simple regular care, you’ll enjoy smoother mowing, better performance, and a yard you can be proud of. Happy mowing!
