Winterizing your lawnmower is crucial to ensure it remains in good working condition when spring arrives. Follow these steps to protect your mower from the harsh winter weather:

Clean Thoroughly

Before storing your lawnmower, please give it a deep clean. Remove grass clippings, dirt, and debris from the deck, blades, and other components. This prevents rust and corrosion during the off-season.

Drain the Fuel

Gasoline left in the tank can degrade over time, causing carburetor issues. To prevent this, run the mower until it’s out of fuel or use a siphon to remove the gasoline. Dispose of the old fuel properly.

Change the Oil

Changing the oil before winter is essential for long-term engine health. Drain the old oil, replace it with fresh oil, and consider changing the oil filter if your mower has one.

Remove the Spark Plug

Remove the spark plug to prevent any potential moisture buildup in the combustion chamber. You can add a teaspoon of oil into the cylinder and slowly pull the starter cord a few times to distribute the oil and provide additional protection.

Inspect and Sharpen Blades

Check the condition of the mower’s blades. If they are dull or damaged, sharpen or replace them. Sharp blades ensure a clean cut in the spring.

Stabilize the Carburetor

Use a fuel stabilizer to protect the carburetor from gum and varnish buildup. Follow the manufacturer’s instructions for the correct dosage.

Store Indoors

Store your lawnmower in a dry, sheltered location like a garage or shed whenever possible. If you must leave it outdoors, cover it with a waterproof tarp.

Charge the Battery

If your lawnmower has a battery, ensure it’s fully charged before storing it. You can disconnect the battery to prevent any drainage.

Lubricate Moving Parts

Apply a light coat of lubricant to moving parts like the throttle and control cables. This helps prevent rust and keeps them working smoothly.

Check the Air Filter

Inspect the air filter and replace it if necessary. A clean filter ensures proper air intake when you use the mower again.

By taking these steps to winterize your lawnmower, you’ll increase its longevity and ensure it’s ready for action when the grass starts to grow again in the spring.
