Essential Petrol Lawn Mower Upkeep

A well-maintained lawn is an essential aspect of any home, and a petrol lawn mower is a vital tool to achieve that perfect, green carpet. To ensure the best performance and longevity of your petrol lawn mower, it’s essential to regularly carry out proper upkeep tasks. In this comprehensive guide, we will delve into the best practices for petrol lawn mower maintenance, covering cleaning, storage, and essential checks to keep your mower running smoothly for years to come.

Regular Cleaning

One of the most critical aspects of petrol lawn mower upkeep is ensuring it stays clean. A dirty mower can negatively impact its performance and increase wear and tear on essential components.

  • After each use, remove any grass clippings, dirt, and debris from the mower deck, blades, and wheels to prevent rust and corrosion.
  • Periodically, use a hose or pressure washer to clean the underside of the mower deck, making sure to remove any built-up grass and dirt.
  • Allow the mower to air-dry before storing it away.

Engine Maintenance

The engine is the heart of your petrol lawn mower. Proper care will help extend its life and keep it running efficiently.

  • Regularly check the oil level and change it as recommended by the manufacturer. This will ensure the engine stays lubricated and runs smoothly.
  • Keep the air filter clean, as a dirty filter can reduce engine efficiency and cause it to overheat. Replace it as needed.
  • Inspect the spark plug for wear and tear, and replace it if necessary. A properly functioning spark plug ensures optimal combustion and engine performance.

Blade Care

Sharp blades are crucial for a clean, even cut. Dull blades can damage the grass and make your lawn appear uneven and unhealthy.

  • Check the blades regularly for signs of wear, and sharpen them as needed. You can either sharpen the blades yourself using a blade sharpener or take them to a professional.
  • If the blades are damaged or excessively worn, replace them to maintain optimal cutting performance.

Fuel Management

Proper fuel management is crucial for the efficient operation of your petrol lawn mower.

  • Use fresh, high-quality fuel, and avoid using fuel that has been sitting for more than 30 days.
  • Add a fuel stabilizer to the fuel tank, especially during winter storage. This helps prevent the fuel from degrading and causing issues with the engine.
  • Drain the fuel tank and carburetor before storing the mower for an extended period.

Inspect and Maintain Tires

Properly inflated and maintained tires ensure easy maneuverability and even cutting.

  • Regularly check the tire pressure and inflate them to the recommended level. Underinflated tires can cause uneven cutting and make the mower harder to push.
  • Inspect the tires for signs of wear and replace them as needed.

Cable and Control Check

Regularly inspect the cables and controls to ensure smooth operation and safety.

  • Check the throttle, brake, and drive cables for any signs of wear or damage. Replace them if necessary.
  • Ensure all controls and safety features are functioning correctly.

Winter Storage

Proper storage during the winter months is essential for maintaining the longevity of your petrol lawn mower.

  • Thoroughly clean the mower before storing it away.
  • Drain the fuel tank and carburetor, or add a fuel stabilizer to prevent fuel degradation.
  • Remove the spark plug and add a few drops of engine oil into the cylinder. Pull the starter cord slowly a few times to distribute the oil and protect the engine from corrosion.
  • Store the mower in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.


Proper upkeep of your petrol lawn mower is essential for ensuring its optimal performance, efficiency, and longevity. By following the maintenance tips outlined in this guide, you can keep your mower running smoothly and effectively for years to come. Regular cleaning, engine maintenance, blade care, fuel management, tire inspections, cable and control checks, and proper winter storage are all crucial aspects of petrol lawn mower upkeep.

Remember that a well-maintained lawn mower not only improves the appearance of your lawn but also saves you time, effort, and money in the long run. By investing a little time and effort into proper maintenance, you can enjoy a beautiful, healthy lawn and a reliable, efficient mower for years to come.
