Tip: Cleaning the engine and changing the oil can keep your mower running smoothly. According to experts, “Replacing oil, spark plugs, and air filters on mowers” should be part of your routine.

Longevity

Proper maintenance extends the life of your mower. Think of it like taking care of your car. Regular check-ups and minor repairs can keep it running for years.

Case Study: One user on Reddit mentioned using an $80 push mower for over a decade with minimal maintenance. This shows that even basic care can significantly extend your mower’s life.

Prevent Costly Repairs

Ignoring maintenance can lead to expensive repairs. Small issues, like a dirty air filter or dull blade, can escalate into major problems if left unchecked.

Fact: A well-maintained mower is less likely to break down. Regular maintenance tasks, such as “inspecting and replacing filters” and “sharpening or replacing the mower blade,” can prevent these costly repairs.

Conclusion

In summary, end of season lawn mower maintenance is essential for improved engine performance, increased longevity, and preventing costly repairs. Taking these simple steps now can save you time and money in the long run.

Step-by-Step Guide to Winterizing Your Lawn Mower

Step 1: Clean Under the Mower Deck

Grass clippings and debris can build up under the mower deck, causing rust and reducing performance. Use a putty knife and wire brush to scrape off the grass and mud. This simple task can prevent rust and keep your mower working efficiently.

Pro Tip: Cleaning under the deck improves your mower’s mulching and bagging performance.

Step 2: Change the Engine Oil

Old oil can cause corrosion and reduce engine life. Changing the oil at the end of the season ensures that your mower is ready for next year.

1. Disconnect the spark plug to prevent accidental starts.
2. Remove the drain plug and let the old oil drain into a safe container.
3. Replace the drain plug and fill the engine with fresh oil.

Note: Use oil formulated for small engines, such as SAE 30 or 30-weight oil, to improve engine life.

Step 3: Inspect and Replace Filters

Filters keep your engine running smoothly by removing dirt and debris.

• Air Filter: Replace paper filters or clean foam filters with warm, soapy water. Let them dry completely before reinstalling.
• Fuel Filter: Check your operator’s manual for specifics. Replace if it looks dirty or clogged.

Fact: Clean filters improve combustion and engine efficiency.

Step 4: Stabilize Fuel and Fuel System

Fuel can go stale in as little as 30 days, leading to gumming and clogs. Adding a fuel stabilizer, like Sta-Bil Fuel Stabilizer, can prevent these issues.

1. Add stabilizer to the gas tank.
2. Run the mower for a few minutes to distribute the stabilizer through the system.
3. Run the mower dry to empty the fuel lines.

Pro Tip: This step prevents gumming and keeps your fuel system clean.

Step 5: Disconnect and Replace the Spark Plug

A worn-out spark plug can make starting your mower difficult.

1. Disconnect the spark plug to avoid accidental starts.
2. Use a spark plug socket to remove the old plug.
3. Install a new spark plug.

Fact: A new spark plug can improve ignition and ensure a smooth start in the spring.

Step 6: Sharpen or Replace the Mower Blade

A sharp blade cuts grass more efficiently and reduces stress on the engine.

1. Remove the blade by unscrewing the bolts.
2. Sharpen the blade with a file or replace it if it’s damaged.
3. Reattach the blade securely.

Note: Sharpening or replacing the blade improves cutting efficiency and keeps your lawn looking its best.

Step 7: Store the Mower Properly

Proper storage can prevent moisture damage and extend the life of your mower.

• Dry Location: Store your mower in a dry place to prevent rust and corrosion.
• Avoid Ignition Sources: Keep the mower away from any sources of ignition to avoid accidents.

Pro Tip: Storing your mower properly ensures it’s ready to go when the next mowing season arrives.

Additional Tips for End of Season Lawn Mower Maintenance

Consider Engine Fogging

In regions with damp climates, internal engine corrosion can be a big problem. Fogging oil is a special spray that you can use to coat the internal parts of your engine, like the piston, cylinder, and valves. This process, known as engine fogging, helps prevent corrosion during the off-season.

To use fogging oil:

1. Remove the air filter.
2. Spray fogging oil into the air intake while the engine is running.
3. Let the engine consume the last bit of fuel while spraying the oil.

This simple step can make a huge difference, especially if your winters are cool and damp.

Oil the Axles and Controls

Smooth operation is key to a well-functioning lawn mower. Applying a few drops of machine oil to each wheel axle and all control pivot points can significantly reduce wear and tear.

• Axles: A couple of drops on each wheel axle.
• Controls: Oil any moving parts or pivot points.

This small task can prevent rust and ensure your mower operates smoothly when spring arrives.

Inspect Drive Belts and Wheels

Don’t forget to check the drive belts and wheels. These parts can wear out or crack over time, especially with the vibrations from mowing.

• Drive Belts: Look for cracks or frayed edges. If you notice any damage, replace the belt to maintain smooth operation.
• Wheels: Inspect for any damage. If the wheels are cracked or damaged, swap them out for new ones.

By taking these steps, you’ll improve your mower’s mobility and ensure it’s ready for the next mowing season.

Pro Tip: Regularly inspecting and maintaining these parts can prevent costly repairs down the line.

Next, let’s dive into some frequently asked questions about end of season lawn mower maintenance.

Frequently Asked Questions about End of Season Lawn Mower Maintenance

What to do with lawnmower at end of season?

At the end of the mowing season, it’s crucial to give your lawn mower some TLC. Here’s a quick checklist:

• Clean the deck: Remove grass buildup to prevent rust and improve performance.
• Change the oil: Old oil can corrode the engine. Fresh oil keeps it running smoothly.
• Inspect and replace filters: Clean or replace the air and fuel filters to ensure proper combustion.
• Replace the spark plug: A new spark plug helps with ignition and prevents accidental starts.
• Stabilize the fuel: Add a fuel stabilizer to prevent gumming and keep the fuel fresh.

Is it okay to leave gas in a lawn mower over winter?

Leaving gas in your mower over winter is not recommended. Gasoline can go stale in as little as 30 days and cause clogs and corrosion. Here’s what you should do:

• Use a fuel stabilizer: Adding a stabilizer like Sta-Bil can keep the gas fresh and prevent gumming.
• Run the engine: After adding the stabilizer, run the mower for a few minutes to circulate it through the system.
• Fill the tank: Keeping the tank full discourages water buildup and phase separation.

Should I drain oil from my lawn mower for winter?

Draining the oil from your lawn mower for winter storage is not necessary. Here’s why:

• Oil doesn’t deteriorate: Unlike gasoline, oil doesn’t go bad over winter.
• Change if needed: If the oil is dirty or hasn’t been changed in a while, it’s a good idea to replace it.

Pro Tip: Always disconnect the spark plug before performing any maintenance to avoid accidental starts.

By following these steps, you can ensure your lawn mower stays in top shape and is ready for action come spring.
