When you have to store your lawn mower, make sure that you take the following precautionary measures to avoid damage to the unit. First things first, if you have a battery-operated model, remove the battery and place it in a dry place away from fire hazards like gas cans.
Make sure that the lawn mower is completely clean and dry before storing it away. It has undoubtedly accumulated a lot of leaves, mud, and debris during its service days, so hose everything off. Before doing this, take out the spark plug wire to prevent accidents.
As much as you can, wipe dry the mower to eliminate the risk of rust and corrosion. If you use a gas-powered mower, use a fuel stabilizer. The fuel system can end up all clogged up if the gas remains unused. For storage times longer than one month, add this type of product to the fuel system to prevent such mishaps.
