Winterizing your lawn mower is essential to keep it in good condition during the off-season. Here’s a step-by-step guide:

1. Empty the Fuel Tank

Why: Old fuel can degrade and gum up the engine.

How:

  • Run the mower until it stops to use up any remaining fuel.
  • Alternatively, add a fuel stabilizer to prevent the fuel from degrading if you don't plan to empty it.

2. Clean the Mower

Why: Dirt, grass, and debris can cause rust or attract pests.

How:

  • Use a stiff brush or compressed air to remove grass clippings and dirt.
  • Turn the mower off and disconnect the spark plug before cleaning under the deck.
  • Hose down the exterior if necessary, and let it dry completely.

3. Change the Oil

Why: Old oil can contain contaminants that damage the engine.

How:

  • Drain the old oil while the engine is slightly warm.
  • Refill with fresh oil according to the manufacturer’s specifications.

4. Remove or Maintain the Battery

Why: Batteries can lose charge or corrode over time.

How:

  • Disconnect and remove the battery.
  • Store it in a cool, dry place.
  • Use a trickle charger to maintain the charge.

5. Inspect and Clean the Spark Plug

Why: A fouled or worn spark plug affects performance.

How:

  • Remove the spark plug and inspect it for damage.
  • Clean it with a wire brush or replace it if it’s worn.

6. Sharpen or Replace the Blade

Why: Dull blades tear grass instead of cutting it cleanly.

How:

  • Remove the blade and inspect for damage or dullness.
  • Have someone sharpen, or replace if necessary.

7. Lubricate Moving Parts

Why: Prevents rust and keeps the mower operating smoothly.

How:

  • Apply lubricant or oil to pivot points, wheels, and cables.

8. Check the Air Filter

Why: A dirty air filter reduces engine efficiency.

How:
  • Remove the filter and inspect it.
  • Replace a paper filter or clean a foam filter with soapy water (let it dry completely before reinstalling).

9. Store Properly

Why: Protects the mower from damage and weather.


How:

  • Store the mower in a dry, sheltered location.
  • Cover it with a tarp or mower cover if needed.

These steps ensure your mower stays in good shape and starts reliably next spring!
