A functional lawn mower is necessary for keeping your yard healthy and presentable. Regular maintenance will make your mower more efficient while extending its life, helping avoid costly repairs or replacements.
Whether you have a gas-powered mower or a riding mower for large tasks, taking care of your equipment is an ongoing process. This guide will explore how to make your lawn mower run better for longer.
1. Clean or Replace the Air Filter
A lawn mower’s air filter prevents debris from entering the engine, which can obstruct airflow. Clean foam air filters regularly with warm, soapy water and dry them thoroughly before adding a drop or two of engine oil for lubrication. A simple air filter replacement is best if it looks dirty or damaged. Keep this task at the top of your maintenance routine to facilitate proper engine combustion, leading to better mower performance.
2. Sharpen the Blade

A sharp blade cuts grass effectively. Dull blades tear the grass instead of slicing it, leaving your lawn susceptible to disease and pests. Sharpen the blade at least once per mowing season, or more often if you frequently encounter rocks or thick branches.
To sharpen it, detach the blade carefully, clamp it, and use a metal file or grinder to restore its edge. This step keeps your mower working efficiently while improving the health of the lawn.
3. Check and Balance the Wheels
Uneven wheels can create an inconsistent cut and stress the mower’s mechanism, especially in models with adjustable wheel heights. Inspect the mower’s wheels regularly for misalignment. Tighten any loose wheel bolts and correct uneven wheels with minor adjustments. If the wheels are beyond repair, replace them with compatible parts from the mower’s manufacturer. Regular maintenance keeps your mower running smoothly and your lawn looking its best.
4. Replace the Spark Plug
The spark plug is a vital part of your mower’s ignition system. Over time, it wears out or becomes fouled, making the engine harder to start. Check your push mower spark plug at the beginning of the mowing season and replace it if you notice discoloration or damage. Thankfully, spark plugs are inexpensive and easy to change. A high-quality option, like those offered by E3 Spark Plugs, provides better combustion for your mower to start without unnecessary effort.
5. Adjust the Mower Deck
The mower deck houses the blade and adjusts the cutting height of your lawn. Periodically inspect it for debris or grass buildup, as these can compromise cutting performance. Adjust the deck to an appropriate height for your grass type to avoid scalping your lawn or stressing the engine. Additionally, make sure the deck is level to achieve an even cut across your yard.
Clean the underside of the mower deck regularly to prevent rust and maintain performance. Check for any damage that could affect the blade’s rotation. Lubricate moving parts, like the deck wheels or height adjustment mechanisms, to keep them functioning smoothly.
6. Inspect the Fuel System
Fuel quality is pivotal to your mower’s health. Use fresh gasoline and avoid letting fuel sit in the tank for extended periods because it can deteriorate and clog the carburetor. If your mower is not starting or stalling frequently, inspect the fuel lines and filter for damage or blockages. Adding a fuel stabilizer can help prevent issues during storage.
Always drain old fuel before refilling the tank to avoid contamination. Clean the carburetor and check your owner’s manual for the recommended fuel type.
7. Change the Oil

Like a car engine, a lawn mower engine relies on clean oil to function properly. Engine oil lubricates moving parts and prevents overheating. Check the oil level regularly and replace it according to the manufacturer’s recommendations, typically after 25 to 50 hours of use. Drain the old oil and refill your mower with new oil suitable for its engine type. Neglecting oil changes can lead to sludge buildup, reduced engine performance, or even total failure.
8. Store Your Mower Properly
Proper storage protects your lawn mower when you’re not using it. After finishing your last mow of the season, clean the mower thoroughly. Remove grass clippings and dirt from the deck, engine housing, and blades.
If possible, store your mower in a dry, covered shed or garage to prevent rust and degradation. For long-term storage, consider draining the fuel and removing the battery from electric mowers. Check the spark plug and air filter and apply a light coat of oil to the blades to prevent rust during the off-season. Cover up the mower with a protective tarp during storage.
9. Schedule Regular Tune-Ups
Even with diligent care, it’s beneficial to have your mower professionally serviced. A tune-up typically includes a complete inspection, oil change, blade sharpening, and replacing worn parts like the air filter or spark plug. Scheduling annual maintenance identifies potential problems and keeps your mower running at peak performance.
Professional service can extend the mower’s lifespan, saving you money in the long run. Technicians also check for fuel system issues, which can go unnoticed. Regular maintenance improves fuel efficiency, making yard work smooth and cost-effective.
10. Know When To Upgrade
Despite your best efforts, lawn mowers don’t last forever. If repairs start to cost more than the mower’s value or if performance consistently declines, upgrading may be your best option. Investing in newer models with advanced features could save you time and deliver better results.
Modern push mowers often come with improved fuel efficiency, reducing long-term costs. Many new models also offer adjustable cutting heights, making it easier to maintain your lawn’s appearance. Look for options with ergonomic designs to make mowing more comfortable and less tiring.
Keep Your Lawn Mower Running Like New
By following these steps, you’ll make your lawn mower run better for longer. Regular maintenance tasks, such as checking the air filter, sharpening the blade, and inspecting the spark plug, are efforts that yield considerable results. Consistent care prolongs the life of your equipment and improves its overall efficiency, making yard work an easier and more successful endeavor.
