A robotic lawnmower can be a considerable relief in the garden, but what happens if the boundary wire or control cable is damaged? In this blog post, I describe step by step how I quickly and easily repaired the defective control cable and the broken boundary wire on my robotic lawnmower. A cable break on the boundary wire of my robotic lawnmower recently presented me with a challenge. While I was out with the gas mower, the mower was set too low and cut the boundary wire. Although the cable was laid in the ground, it was completely cut through.
