Continue mowing your lawn as needed up until around Thanksgiving. Lower the mower blade height slightly each time you mow until the grass blades are approximately two inches high. Mowing through the late fall will help to strengthen the lawn through the winter.
Before you store your lawn mower for the winter be sure to take these steps:
1. Always disconnect the spark plug before doing any work on the mower.
2. Run the mower until the fuel tank is empty. Keep the tank empty until you need it next spring. If there is an oil tank be sure to empty that too and dispose of it properly.
3. Use a soft brush and hot, soapy water to remove any grease and leftover materials in the mower.
4. Use steel wool to remove any rust that has formed. Be sure to wear gloves!
5. Remove the mower blade and have it sharpened for next spring at your local independent hardware store.
6. Clean or replace the air filter.
