This product is made of high-quality materials with excellent rust resistance and long durability, designed to provide enhanced traction for robot mowers on wet or sloping lawns, helping to prevent slipping and maintain optimal operation performance. It is easy to install and improves mowing efficiency while protecting the lawn from damage, keeping it well-maintained and neat. The material offers strong resistance to moisture, soil, and other environmental factors, maintaining a clean appearance over time. Its high tensile strength and hardness ensure the anti-slip nails resist deformation and wear under repeated pressure and friction, extending the overall service life, reducing replacement frequency, and lowering maintenance costs. The design has been carefully calculated and tested to deliver effective traction without causing excessive lawn damage.
