It is typically recommended that robotic lawn mower blades are replaced every 3 months when cutting lawns greater than 300m2. When cutting lawns smaller than this, the blades will need to be changed less frequently. The lifetime of the blades also depends on the type of grass and soil of your lawn.
A dull or blunt mower blade is more likely to tear the grass, resulting in a poor finish to your lawn.
Replacement mower blades are available at the Official Flymo WebShop. Part Number – 2405054OH.
