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 performance. The spikes are easy to install and can improve mowing efficiency while protecting the lawn from damage, keeping it neat and well-maintained. The material offers excellent resistance and can maintain a clean appearance even when exposed to moisture, soil, and other outdoor conditions over time. High tensile strength and hardness ensure the anti-slip nails resist deformation and wear under repeated pressure and friction, extending the overall service life and reducing the need for frequent replacements. The spike design has been carefully calculated and tested to deliver effective traction without causing excessive impact on the lawn surface.
