A lawnmower is an important purchase. Many mulching mowers can cost upward of $300. For this investment to last, routine care and maintenance is vital. Preparing a mower for winter is as important as priming it for the spring and summer mowing season. Caring for your mower every season will help bring years of beauty to your lawn.
How to Winterize a Push Lawn Mower
Empty the gasoline from the mower by mowing until the tank runs empty. This is the best method for gas removal. A siphon can also be used to remove gasoline from the tank. Transfer any unused gasoline removed in this manner to your car's gas tank. Unplug the spark plug wire from the spark plug with a gloved hand. The spark plug will be hot if the mower was recently running. This will ensure the mower cannot start accidentally when performing maintenance.
Turn the mower on its side. Place a piece of wood against the blade to prevent it from turning. Scrape the underside of the mower with a putty knife to remove the dead grass and debris from the mower. Continue until all grass and debris have been cleared from the underside of the mower. Remove the piece of wood, and turn the mower right side up. Store the mower in a shed or other structure for the winter to prevent damage from the elements.
Inspect the blade to determine if it needs sharpening or replacement in the spring before mowing season begins. Most blades will need attention once per year--either sharpening or replacement. Change the oil and air filter in the mower, according to the manufacturer's directions before use each spring. Replace the spark plug and refill the gas tank. The mower is now ready for another summer mowing season.
