With the Gardena 4090-20 pegs, you securely anchor the boundary and guide wire of your robotic lawnmower into the ground. This keeps cables firmly pinned flat against the turf surface and prevents them from shifting or being damaged by rotating mower blades. On uneven lawns and undulating ground, placing pegs at shorter intervals ensures smooth, trouble-free cable tracking. This handy pack of 100 plastic ground stakes gives you everything you need to outline a new mowing area or adapt an existing installation for your Gardena robotic mower.
