Lawn Mower Maintenance Schedule: Monthly & Seasonal Checklist

A well-maintained lawn mower is the key to keeping your yard looking its best throughout the year. Whether you own a small push mower or a sleek zero-turn riding mower, regular maintenance will ensure it operates efficiently, lasts longer and prevents costly repairs down the road. At American Power Equipment, we believe that following a structured maintenance schedule is the best way to keep your mower in excellent condition. Below, we’ve outlined a comprehensive monthly and seasonal checklist to help you keep your mower running smoothly.

Why Lawn Mower Maintenance Matters

Lawn mowers are hardworking machines, and they encounter dirt, grass clippings and other debris every time they’re used. Without proper upkeep, these factors can lead to engine strain, dull blades and mechanical issues. Routine maintenance not only ensures your mower works effectively but also extends its lifespan and reduces the risk of expensive repairs. Additionally, a well-maintained mower ensures a cleaner, more precise cut for a healthier lawn.

Monthly Lawn Mower Maintenance Checklist

Incorporating monthly maintenance into your routine will help you identify and resolve minor issues before they turn into major problems. Here’s what you should check every month:

1. Clean the Mower Deck

Remove grass clippings, dirt and debris from under the mower deck. A clogged deck can impact cutting performance and airflow. Use a hose or a scraper to clean the deck thoroughly. Some models have a washout port to make this process easier.

2. Check and Sharpen the Blades

Inspect the mower blades for dullness, nicks or bends. Dull blades tear grass instead of cutting it, which can lead to lawn discoloration or damage. Sharpen the blades if they’ve become dull, or replace them if they’re excessively worn.

3. Inspect the Air Filter

Check the air filter for clogs or damage. A dirty filter can restrict airflow and reduce engine performance. Replace foam filters every three months or as needed, and replace paper filters if they appear dirty.

4. Check Tire Pressure (for Riding Mowers)

Uneven tire pressure can cause uneven mowing and strain on the mower’s components. Ensure all tires are inflated to the manufacturer’s recommended PSI.

5. Inspect the Drive Belt (for Riding Mowers)

Check the drive belt for signs of wear, cracks or fraying. A damaged belt should be replaced immediately to avoid equipment failure.

6. Inspect Fuel Levels and Quality

Ensure the fuel tank is filled with fresh gas. Avoid using fuel that has been sitting for more than 30 days, as old gas can clog the carburetor.

Seasonal Lawn Mower Maintenance Checklist

In addition to monthly tasks, there are several seasonal maintenance steps you should perform to prepare your mower for peak use and storage.

Spring Maintenance: Prepare for the Mowing Season

Spring marks the start of the mowing season, and it’s essential to get your mower ready for the months ahead.

Oil Change: Drain old oil and replace it with fresh, manufacturer-recommended oil. This ensures proper engine lubrication.

Replace the Spark Plug: Inspect the spark plug for corrosion or wear. Replace it if necessary to ensure reliable starts.

Inspect the Battery (for Riding Mowers): Clean the battery terminals and check for a strong charge. Replace the battery if it no longer holds a charge effectively.

Inspect and Tighten Bolts and Fasteners: Check all bolts, nuts and screws to ensure they’re securely tightened.

Install Fresh Blades: After sharpening or replacing blades, ensure they’re securely installed.

Summer Maintenance: Keep the Mower Running Smoothly

During peak mowing season, extra attention will help your mower handle frequent use.

Clean After Every Use: Remove grass and debris from the deck, blades and air filter after each use to prevent buildup.

Monitor Engine Performance: Listen for unusual noises or reduced power during operation. Address any issues promptly to prevent further damage.

Keep the Blades Sharp: Sharpen blades more frequently during summer due to increased use.

Inspect for Leaks: Check for fuel or oil leaks and resolve them immediately to avoid engine damage or hazards.

Fall Maintenance: Prepare for Storage

As the mowing season winds down, proper fall maintenance ensures your mower is ready for winter storage.

Run the Mower Until Empty: Allow the mower to run until it’s out of fuel. Alternatively, add a fuel stabilizer to prevent gas from deteriorating.

Clean the Mower Thoroughly: Remove all grass clippings and debris from the deck, wheels and engine area.

Remove the Battery (for Riding Mowers): Disconnect and store the battery in a cool, dry place to prolong its lifespan.

Store the Mower Properly: Store your mower in a dry, covered area. For added protection, use a weatherproof cover.

General Tips for Lawn Mower Maintenance

Use the Right Fuel and Oil: Always use fresh gas and the recommended oil type to ensure optimal engine performance.

Follow the Manufacturer’s Manual: Your mower’s manual contains specific instructions and maintenance intervals for your model.
