How To Winterize A Lawn Mower?

When the colder months approach, it’s important to prepare your lawn mower for the winter season. Properly winterizing your lawn mower can help prevent damage and ensure it starts up smoothly when spring arrives. Follow these 7 essential steps to winterize your lawn mower and keep it in top condition:

Step 1: Empty the Gas Tank

Begin by emptying the gas tank of your lawn mower. Storing a mower with fuel in the tank can lead to residue buildup and potentially damage the engine. Either run the engine until the fuel is depleted or use a siphon to remove the gasoline.

Step 2: Disconnect the Spark Plug

Next, disconnect the spark plug wire to prevent accidental starts while performing maintenance. This step ensures your safety and allows you to work on the mower without any risk of the engine firing up.

Step 3: Remove the Blade

Removing the blade is crucial for winterizing your lawn mower. Sharpen the blade if necessary or have it professionally sharpened. Dull blades can tear grass instead of cleanly cutting it, leading to an unhealthy lawn.

Step 4: Drain the Oil

Drain the oil from the mower’s engine and replace it with fresh oil. Over time, oil can become contaminated with debris, affecting engine performance. By changing the oil before winter storage, you ensure proper lubrication for the engine.

Step 5: Clean the Undercarriage

Inspect the undercarriage of your lawn mower and remove any grass clippings, dirt, or debris that may have accumulated. A clean undercarriage prevents corrosion and promotes airflow, aiding in proper mower function.

Step 6: Change the Air Filter

Check the air filter and replace it if necessary. A clogged air filter restricts airflow to the engine, leading to reduced performance. Installing a new air filter ensures optimal operation when you use the mower again.

Step 7: Replace the Spark Plug

Install a new spark plug in your lawn mower to ensure reliable starts and efficient combustion. A worn-out spark plug can cause hard starting or rough running. Replacing it as part of winterization helps maintain engine performance.

Step 8: Safely Stow any Combustibles

Store your lawn mower in a safe, dry location away from any combustible materials. Proper storage prevents fire hazards and protects your mower from environmental damage. Consider covering the mower with a tarp for added protection.
