When to Replace

• Replace blades when the cutting edge becomes dull, chipped, or rounded, resulting in torn grass tips.
• Inspect for metal fatigue, excessive wear, or structural damage after striking rocks, stumps, or hard debris.
• Change blades if they show signs of bending or uneven wear patterns that cause vibration during operation.

Installation Tips

• Disconnect the spark plug wire and engage the parking brake before performing maintenance.
• Use a wooden block to wedge the blade and prevent it from rotating while loosening the mounting hardware.
• Clean the underside of the mower deck to ensure a balanced fit and clear airflow.
• Ensure the blades are installed with the cutting edge oriented in the correct direction of rotation.
• Torque the mounting bolts to the manufacturer's recommended specifications to ensure secure attachment.
