First, disconnect the spark plug for safety. Then, remove the mower deck and use a wrench to loosen the blade bolts. Replace the blades and ensure they are securely fastened before reattaching the deck.

Regular maintenance should be performed every 25 hours of operation, including checking the oil, air filter, and tire pressure, as well as inspecting belts and blades.
Check the battery connections and charge if necessary. Ensure the fuel tank has fresh gasoline and the fuel filter is not clogged. Also, inspect the spark plug for wear or damage.
