Winterizing Your Lawn Mower: Are You Ready for the Snow?

The crisp air is starting to bite, the leaves are changing colors, and the days are getting shorter. Fall is officially here, which means it’s time to put away your lawn mower and prepare it for winter. Neglecting this crucial step could lead to costly repairs and a frustrating spring start-up. This comprehensive guide will walk you through the essential steps to winterize your lawn mower, ensuring it’s ready to tackle the green expanse next spring.

Winterizing your lawn mower involves a series of steps designed to protect the engine and other vital components from damage caused by cold temperatures, moisture, and prolonged inactivity. The process typically includes draining fuel, cleaning, changing oil, and storing the mower in a dry, protected location.

Fuel Up for the Winter (or Down, in This Case)

The first step to winterizing your lawn mower is to eliminate the possibility of fuel going bad. Old fuel can gum up the carburetor and fuel lines, leading to difficult starts or even engine failure.

Empty the Fuel Tank

  • Step 1: Start by running the mower until the fuel tank is nearly empty. This ensures the least amount of fuel remains in the system.

Add Fuel Stabilizer

  • Step 2: Add a fuel stabilizer to the remaining fuel in the tank. This product prevents the fuel from breaking down and forming varnish or gum over time. Follow the instructions on the product label for the appropriate amount to use.

Run the Engine

  • Step 3: Run the engine for a few minutes to allow the stabilized fuel to circulate throughout the fuel system.

Cleaning Up for a Fresh Start

A clean lawn mower is a happy lawn mower. Before storing it for winter, take the time to clean it thoroughly to prevent rust and corrosion.

Give it a Good Scrub

  • Step 1: Use a brush or cloth to remove any dirt, grass clippings, and debris from the exterior of the mower. Pay particular attention to the underside of the deck, where grass clippings tend to accumulate.

Clean the Air Filter

  • Step 1: Remove the air filter and tap out any loose dirt or debris. If it’s heavily soiled, wash it with mild soap and water, allowing it to air dry completely before reinstalling it.

Inspect the Spark Plug

  • Step 1: Remove the spark plug and use a wire brush to clean off any carbon deposits. If the spark plug looks worn or damaged, replace it with a new one.

Sharpen the Blades

  • Step 1: Sharpen the mower blades to ensure they cut cleanly and efficiently next season. You can use a sharpening file or a grinding wheel to achieve a sharp edge.

Changing the Oil: The Lifeblood of Your Engine

Changing the oil in your lawn mower is essential to prevent sludge and deposits from accumulating over winter, which can damage the engine.

Warm Up the Engine

  • Step 1: Start the engine and let it run for a few minutes to warm up the oil.

Drain the Old Oil

  • Step 2: Locate the oil drain plug (usually on the bottom of the engine) and place a drain pan underneath. Unscrew the drain plug and allow the old oil to drain completely.

Refill with New Oil

  • Step 3: Replace the drain plug and tighten it securely. Carefully pour the recommended type and amount of oil into the engine’s oil fill port. Refer to your owner’s manual for specific recommendations.

Storage Solutions: Keeping It Safe and Sound

The way you store your lawn mower is crucial for its longevity. Proper storage protects it from the elements and prevents damage.

Choose a Dry Location

  • Step 1: Select a dry, well-ventilated area to store your mower. An enclosed shed, garage, or basement are ideal options. Avoid storing it in damp or humid environments, as this can lead to rust and corrosion.

Elevate the Mower

  • Step 1: Place the mower on blocks or a stand to raise it off the ground. This will prevent moisture from accumulating under the deck and causing damage.

Cover It Up

  • Step 1: Cover the mower with a tarp or a lawn mower cover to protect it from dust, debris, and moisture.

Preparing for Spring: A Quick Refresher

When spring arrives, it’s time to get your lawn mower ready to tackle the growing grass.

Remove the Cover

  • Step 1: Remove the tarp or cover from the mower and inspect it for any signs of damage.

Check the Oil Level

  • Step 1: Check the oil level and add more if necessary.

Prime the Engine

  • Step 1: Prime the engine by pumping the fuel primer bulb until fuel is visible in the carburetor.

Start the Engine

  • Step 1: With the choke engaged, pull the starter cord to start the engine. Once it’s running, release the choke and let it warm up for a few minutes.

Beyond the Basics: Additional Winterizing Tips

For added protection, you can take several additional steps to winterize your lawn mower:

  • Clean the Battery: Remove the battery from the mower and clean its terminals with a wire brush. Store the battery in a cool, dry place.
  • Check Tire Pressure: Check the tire pressure and inflate them to the recommended level.
  • Sharpen the Blades: Even though you sharpened the blades before storage, it’s a good idea to give them a quick once-over before spring use.

Conclusion: A Smooth Start to Spring

By following these simple steps, you can ensure your lawn mower is well-protected during the winter months. This will save you time, money, and frustration when it comes time to start mowing again in the spring. With a properly winterized mower, you can be confident that it will be ready to tackle the green expanse, leaving you with a beautifully manicured lawn.

FAQs

1. Why should I winterize my lawn mower?

Winterizing your lawn mower is crucial to ensure its longevity and optimal performance when you fire it up again in the spring. Leaving your mower out in the elements can lead to corrosion, gumming of internal parts, and damage from freezing temperatures. By winterizing your lawn mower, you can prevent these issues and save yourself from costly repairs or replacements in the future.

2. When should I winterize my lawn mower?

The best time to winterize your lawn mower is after your last mowing session of the season, typically in late fall. Once the weather starts to cool and you’re no longer needing to mow your lawn, it’s time to prepare your mower for the winter months. This gives you ample time to perform the necessary maintenance before temperatures drop too low.

3. What are the essential steps to winterize my lawn mower?

Winterizing your lawn mower involves several key steps:

  • Cleaning: Thoroughly clean the exterior and underside of your mower, removing grass clippings, debris, and dirt.
  • Fuel: Drain the old gas from the tank and carburetor, then fill the tank with fresh, stabilized gas.
  • Oil Change: Change the engine oil and filter, ensuring you use the correct type of oil for your mower.
  • Spark Plug: Check and clean or replace the spark plug, as necessary.
  • Blade Sharpening: Sharpen the blades for optimal cutting performance next season.
  • Storage: Store your mower in a dry, clean place, preferably covered to protect it from dust and moisture.

4. Can I leave fuel in the lawn mower over winter?

Leaving fuel in your lawn mower over winter is a recipe for problems. Gasoline breaks down over time, especially in cold temperatures, and can gum up the carburetor and fuel lines. This can make it difficult to start your mower in the spring and can even lead to engine damage.

5. How do I clean the carburetor?

Cleaning the carburetor is essential to remove any residue or debris that could prevent proper fuel flow. You can use a carburetor cleaner specifically designed for lawn mowers. Follow the instructions on the cleaner to ensure proper application. You may need to remove and disassemble the carburetor for thorough cleaning.

6. Do I need to winterize a riding lawn mower?

Yes, riding lawn mowers also require winterizing, although the specific steps may vary slightly. You’ll still need to clean the mower, drain the fuel, change the oil, and sharpen the blades. Additionally, you may need to check the battery and recharge or remove it for storage.

7. Can I use a lawn mower in the winter?

While some people may use their lawn mowers to clear snow in the winter, this is not recommended for most lawn mowers. The cold temperatures can affect the engine performance and put stress on the internal components. Using a snow blower or other winter-specific equipment is a safer and more efficient way to handle snow removal.
