Cut here: Definition of the lawn mowing area with the robotic lawnmowerOnce the GARDENA boundary wire is installed, the GARDENA robotic lawnmower immediately starts mowing grass. You get the 150 m long boundary wire when you buy the robotic lawnmower. For larger areas, you can customize the boundary wire and simply add the desired length. The same wire also acts as a guide wire and shows the robotic lawnmower back to the charging station. Only use the original GARDENA connector to splice two boundary wire.Technical specificationsItem no. 4088-20EAN-Code: 4078500408806
