This product is made of high-quality materials with excellent rust resistance and long durability, designed to provide improved traction for robot mowers on wet or sloping lawns, helping to prevent slipping and maintain consistent operation. It is easy to install and can enhance 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, helping it stay clean and like new over time. Its high tensile strength and hardness ensure the anti-slip spikes resist deformation and wear under repeated pressure and friction, extending the product's service life, reducing replacement frequency, and lowering maintenance needs. The spike design has been tested and optimized to deliver effective traction while minimizing impact on the lawn surface.
