First, if you are storing indoors - it’s important to stabilize the fuel with a full tank of gas in your lawn mower since gas that sits all winter long can clog the carburetor.
Run engine to empty gas.
Alternatively, If you’re storing indoors, run the engine until the gas is gone.
Changing the oil will ensure your lawn mower is in great shape throughout the winter months.
An extra tip for those who are storing their mower in a garage – stick a few mothballs near the engine to avert those nesting rodents. Finally, check your lawn mower for loose screws and bolts or any damages that should be fixed before the off season. Clear out any buildup of grass or debris.
