Properly winterizing your Toro lawn mower prevents engine damage, fuel issues, and rust during the off-season. Follow these steps to ensure it’s ready to go when spring arrives.

Step 1: Empty or Stabilize the Fuel

Gas left in the mower over winter can degrade and clog the carburetor. You have two options:

• Run the mower until it’s out of fuel – Start the engine and let it run until it shuts off.
• Use a fuel stabilizer – If you prefer to leave fuel in, add a fuel stabilizer, run the engine for a few minutes, and turn it off.

Step 2: Change the Oil

• Drain old oil while the engine is warm (not hot) to remove sludge.
• Refill with fresh oil recommended for your Toro model (check the manual).

Step 3: Clean or Replace the Air Filter

• Remove the air filter cover and check the filter.
• If it’s paper, replace it. If foam, wash it with soapy water, dry, and reapply oil.

Step 4: Remove & Inspect the Spark Plug

• Unscrew the spark plug using a wrench.
• Clean it with a wire brush or replace it if worn out.
• Add a drop of oil into the cylinder, pull the starter cord slowly to coat it, and reinstall the plug.

Step 5: Clean the Mower Deck

• Flip the mower on its side (air filter facing up).
• Scrape off grass buildup using a putty knife or wire brush.
• Spray with a hose or air blower to remove debris.

Step 6: Store in a Dry Place

• Keep the mower in a shed or garage to protect it from moisture.
• Cover with a tarp or mower cover to prevent dust and rust.

Conclusion

Winterizing your Toro lawn mower extends its lifespan and prevents engine problems when spring arrives. By draining or stabilizing fuel, changing the oil, cleaning filters, and storing it properly, your mower will be ready to go for the next season.
