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 consistent operation. 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 strong resistance to moisture, soil, and outdoor conditions, maintaining a clean appearance 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 replacement frequency. The spike design has been carefully tested to deliver effective traction without causing excessive lawn damage.
