How often do the blades of a lawn mower need to be replaced?

Observe the condition of the blade: If the blade shows signs of wear, deformation or poor cutting effect during use, it needs to be replaced promptly

Regular maintenance: Regularly clean the dirt, residues and weeds on the blade to prevent their accumulation and affect the cutting effect. During non-usage seasons or when not in use for a long time, the blades should be treated for rust prevention and properly stored

Avoid harsh environments: Do not use on ground that is too hard or contains impurities such as stones to prevent damage to the blade
