This product is made of high-quality material 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 avoid slipping and affecting the operation results. The product is easy to install and not only improves mowing efficiency but also helps protect the lawn from damage, keeping it looking beautiful and tidy. The material offers excellent resistance and can maintain a clean appearance even when exposed to moisture, soil, and other environmental conditions over time. Its high tensile strength and hardness ensure that the anti-slip nails do not easily deform or wear out under repeated pressure and friction, thus extending the overall service life, reducing replacement frequency, and saving on maintenance costs. The design has been carefully calculated and tested to ensure effective traction without causing excessive damage to the lawn.
