•  Wires leading to and from an island should be fastened with 
the same peg
•  Perimeter Islands should either be rectangular or round
Set the Perimeter Wire 
clockwise around the 
obstacle, otherwise 
the mower will drive 
into the Perimeter 
Island or won’t be 
able to mow the 
area around it 
properly.
TIPS
D. Protect Soft Obstacles
Objects such as ower beds, ponds, or small trees must be 
protected by setting Perimeter Islands.
Keep min. 1 m (3.3 ft) between 
islands; if obstacles are closer 
together, use one island
If the distance between an island and the 
perimeter wire is  lower than 1 m (3.3 ft), 
make the obstacle part of  lawn’s edge.
