This product is made of high-quality materials with excellent rust resistance and long durability, designed to provide stronger traction for the robot mower on wet or sloping lawns, helping to prevent slipping and maintain efficient operation. It is easy to install and improves mowing efficiency while protecting the lawn from damage, keeping it neat and attractive. The material offers excellent resistance and can maintain a clean appearance 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 replacement frequency, which helps lower maintenance costs. The design has been carefully calculated and tested to deliver effective traction without causing excessive lawn damage.
