Understanding Your Lawn Mower’s Components

Buy Me A Coffee

Before diving into maintenance, it’s essential to understand the different parts of your lawn mower and their roles in its operation. While the exact configuration may vary depending on the make and model, most lawn mowers have several key components that need regular attention:

Engine: The engine powers the mower and is responsible for driving the cutting blades. It can be either gas-powered or electric, with gas-powered mowers requiring more maintenance.
Blades: The blades are the part of the mower that actually cut the grass. They can become dull over time and should be sharpened regularly.
Air Filter: The air filter keeps debris and dust from entering the engine, ensuring smooth operation. A clogged air filter can lead to poor performance or engine damage.
Spark Plug: The spark plug ignites the fuel in the engine, enabling the mower to start. Over time, the spark plug can wear out or get dirty.
Fuel System: This includes the fuel tank, carburetor, and fuel lines. Poor-quality fuel or a clogged fuel line can cause your mower to run inefficiently.
Wheels and Tires: The wheels of the mower determine how smoothly it moves across the lawn. Check them regularly for signs of wear or damage.
Chassis and Frame: The chassis holds all the components of the mower together. Make sure it remains clean and free of debris.

Familiarizing yourself with these components will help you understand how to properly maintain your mower and prevent unnecessary damage.

Regular Cleaning of Your Lawn Mower

One of the simplest and most important steps in maintaining your lawn mower is regular cleaning. Grass clippings, dirt, and debris can accumulate on the mower over time, affecting performance and potentially causing parts to rust or deteriorate. Here’s how to clean your mower properly:

A. After Every Mowing Session

After each use, take a few minutes to remove grass clippings and dirt from the mower. While the mower is still running, grass and debris can accumulate in various parts of the machine. To clean it effectively:

Turn off the mower and ensure the engine is cool before starting to clean.
Use a scraper or stiff brush to remove any buildup of grass clippings from under the deck. A plastic scraper is ideal because it won’t damage the metal surface.
Clean the blades carefully. Grass can get stuck to the blades, causing them to work inefficiently. Use a cloth or sponge to remove any excess grass. If the blades are heavily coated, you can use a degreaser to clean them.
Check for any debris in the wheels, engine, or other areas of the mower and remove them.

B. Deep Cleaning (Every Season or Every Few Months)

Every few months or at the start of the season, perform a deep cleaning on your mower to keep it running smoothly:

Remove the deck: If possible, remove the mower’s deck to access the internal components more easily.
Clean the air filter: If your mower has an air filter, clean it according to the manufacturer’s instructions. A dirty air filter can reduce engine efficiency and lead to overheating.
Wash the exterior: Use a hose to spray the exterior of the mower, including the engine area. Be cautious not to get the engine too wet. You can also use a mild soap solution and a sponge to clean the outer surfaces.

Sharpening the Blades

Dull blades can damage your grass and cause an uneven cut. Sharp blades ensure a clean, even cut, promoting a healthier lawn. Over time, the blades will naturally become dull, but regular sharpening can help maintain optimal performance. Here’s how to sharpen your mower blades:

A. When to Sharpen the Blades

You should sharpen your mower blades at least once per mowing season. However, if you notice that the mower is tearing the grass rather than cutting it, or if your lawn looks ragged after mowing, it’s time to sharpen the blades.

B. How to Remove the Blades

Before you begin sharpening, make sure to disconnect the spark plug to prevent accidental starting. To remove the blades:

Lift the mower: Use a jack or prop the mower up securely to access the underside.
Loosen the bolts: Use a wrench or socket set to loosen and remove the bolts securing the blades to the mower deck.
Remove the blades: Once the bolts are removed, carefully take out the blades.

C. Sharpening the Blades

Use a sharpening tool: You can use a sharpening file, sharpening stone, or a specialized blade sharpener to sharpen the blades. Hold the blade steady and sharpen the cutting edge at a 30-45 degree angle.
Check for balance: After sharpening, check the balance of the blade by placing it on a nail or rod. If the blade tips to one side, it may be unevenly sharpened. Adjust as necessary.

If the blades are severely worn or damaged, it may be time to replace them instead of sharpening them.

Changing the Oil

For gas-powered mowers, changing the oil is crucial for keeping the engine running smoothly. Dirty or low oil can cause the engine to overheat and damage internal components. Here’s how to change the oil in your lawn mower:

A. When to Change the Oil

Most lawn mower engines should have their oil changed at least once a year, or after every 50 hours of use. However, always refer to the manufacturer’s instructions for specific guidelines regarding oil changes.

B. How to Change the Oil

Warm up the engine: Run the mower for a few minutes to warm up the oil, making it easier to drain.
Drain the oil: Place a pan underneath the oil drain plug, remove the plug, and let the oil drain completely. Be cautious as the oil may be hot.
Replace the oil filter (if applicable): Some lawn mowers have an oil filter. If your mower has one, replace it when changing the oil.
Refill with fresh oil: Once the oil has drained, replace the drain plug and refill the engine with fresh oil. Make sure to use the type of oil recommended by the manufacturer.

C. Dispose of Used Oil Properly

Used motor oil is hazardous to the environment, so make sure to dispose of it properly. Many auto parts stores and recycling centers offer oil disposal services.

Checking and Replacing the Spark Plug

The spark plug is a critical component of your mower’s engine. Over time, spark plugs can become dirty or worn out, making it harder for the engine to start or run efficiently. Here’s how to care for the spark plug:

A. When to Check the Spark Plug

Check the spark plug at least once per season. If you notice that the mower is having trouble starting or running smoothly, the spark plug may need to be cleaned or replaced.

B. How to Check and Clean the Spark Plug

Remove the spark plug: Use a spark plug wrench to remove the spark plug from the engine.
Inspect the spark plug: If the spark plug looks dirty, carbonized, or damaged, clean or replace it. Use a wire brush to clean any debris from the spark plug.
Check the gap: Use a feeler gauge to check the gap between the electrodes. Refer to the manufacturer’s specifications for the correct gap size.
Replace if necessary: If the spark plug is worn or damaged, replace it with a new one. Make sure to install it correctly to avoid engine issues.

Proper Storage and Winterization

When the mowing season is over, proper storage of your lawn mower is essential to ensure it runs smoothly when you bring it out again. Here are some tips for winterizing and storing your mower:

A. Draining the Fuel

If you plan to store your mower for an extended period (e.g., during the winter), it’s a good idea to drain the fuel tank to prevent the fuel from deteriorating and causing engine problems.

Empty the fuel tank: Run the mower until the tank is empty or drain the fuel if necessary.
Add fuel stabilizer: If you want to leave fuel in the tank, add a fuel stabilizer to prevent the fuel from going stale.

B. Store in a Dry Place

Store the mower in a dry, cool location, away from extreme temperatures or humidity. A garage or shed works well, but avoid leaving the mower outside, where it could be exposed to the elements.

C. Cover the Mower

If you store the mower outdoors or in a dusty area, use a cover to protect it from dirt and debris.

Conclusion

Taking care of your lawn mower is essential to ensure its longevity and optimal performance. Regular maintenance tasks such as cleaning, sharpening the blades, changing the oil, and checking the spark plug can make a significant difference in how well your mower runs. By following these steps, you can keep your lawn mower in top shape, saving money on repairs and ensuring that your lawn remains lush and well-maintained year after year.
