Maintenance and Replacement
Blade Maintenance Schedule
Regular inspection and replacement of blades are crucial for maintaining optimal cutting performance and ensuring the longevity of your robotic lawn mower. Blades should be inspected weekly during active mowing seasons.
Replace blades when they show signs of wear, dullness, chipping, or damage. Dull blades can tear grass, leading to an unhealthy lawn and increased power consumption for the mower. The included set of 12 blades and 12 screws is designed to support multiple replacement cycles, providing a practical and cost-effective solution for ongoing maintenance.
