This product is made of high-quality materials with excellent rust resistance and long durability. It is designed to provide stronger traction for the robot mower on wet or sloping lawns, helping to prevent slipping and maintain optimal operation. Easy to install, it improves mowing efficiency while protecting the lawn from damage, keeping it neat and well-maintained. The material offers excellent resistance and can withstand prolonged exposure to moisture, soil, and other outdoor conditions while maintaining a clean appearance. High tensile strength and hardness ensure the anti-slip spikes resist deformation and wear under repeated pressure and friction, extending the overall service life and reducing replacement frequency. The spike design has been carefully calculated and tested to deliver effective traction without causing excessive lawn damage.
