High-Quality Material: Our robotic lawnmower wheel tips are made of stainless steel and polished in an extra production step for a perfect look. All edges of the traction enhancer are deburred. Improved Traction for Robots: When the lawn is wet or the terrain is sloped with many ups and downs, the spikes provide the robotic lawnmower with better grip, preventing it from digging into the lawn. Let your robotic lawnmower stay on track. Quality Screws: With 12 M4 stainless steel screws, installation of the robotic mower tips is made easy. Thanks to the countersunk screw holes, the screws fit perfectly into the spikes, ensuring a flawless appearance for your robotic lawnmower. Easy Assembly: With an intuitive mounting system and 6 included screws per wheel, the spikes attach to the robotic lawnmower in a flash. Use a cordless screwdriver or a manual screwdriver to install them centered on the wheels. Centering is key!
