Setup, Compatibility & Care
Before starting installation, always disconnect the spark plug wire to ensure the mower cannot start accidentally. Always wear heavy-duty gloves when handling the blade to avoid injury from sharp edges. Verify that the blade orientation is correct (usually indicated by an 'up' or 'deck side' stamp) and tighten the mounting bolt to the manufacturer's specified torque settings. For care, inspect the blade after every 5-10 hours of use for nicks or debris build-up. Keep the underside of the mower deck clean, as wet grass accumulation can lead to rust and reduced blade rotation speed.
