When do I need to use the “Adapter for Perimeter Wire” with the perimeter wire in my lawn?

For 2014-2017 Models Only
The Adapter for Perimeter Wire (part number SPP6117A) is required if the resistance of the Perimeter Wire is bigger than 15 Ohm. Normally this happens, when the Perimeter Wire’s lengths exceed 2,000ft (650m). In such case, a mower may start behaving strangely – running in circles or changing direction in the middle of the lawn. If this happens simply connect the adapter between the Base Station Head and the Perimeter Wire plot connector. Confirm that the mower starts working properly.
