2.9 Test the Perimeter Wire Position for Edge Mowing:
As mentioned in Chapter 1, it is best to test the position of the perimeter wire on edge mowing to determine
if any small adjustments need to be made to the wire position before driving the rest of the wire pegs into
place. Because the bumpers are active during edge mode, if the wire is positioned too close to a wall or
other fixed object, the bumper will activate when striking the object then move off the edge to bypass the
obstacle, retuning to the edge. There are other scenarios where the wire may need to be adjusted, such
as along flowerbeds or along street edges where there is a drop off at the curb.
Manually drive the mower approximately 3 feet (1m) from the perimeter wire. Position the Robomow
towards the perimeter wire immediately after the Docking Station in docking zone (See figure 2.13) or
along any edge in a non-docking zone. Insert the controller back into the holder; making sure it is pivoted
down flush with the top. Insure the Perimeter Switch is turned on.
Press the upper scroll arrow once for the
‘Go to dock’
option and press GO.
Walk along the side of the Robomow while it is following the edge. At any point where the mower position
is too far to the outer edge of the lawn area, note this area and slightly move the wire towards the interior.
For example, if the bumper of the mower is hitting the wall of your home while trying to mow the edge, the
wire is too close to this edge and needs to be positioned more towards the interior of the lawn, and away
from the wall. Conversely, if the mower is not mowing close enough to fixed objects like walls or fully onto
adjacent and level areas such as a driveway, the wire needs to be positioned farther from the interior of the
lawn, out towards the wall or driveway. Reposition the wire along each section where a change needs to
be made, usually moving it only a little each time, and then test the edge mowing in this area once again.
Repeat this process for the entire edge until it can complete the perimeter without striking any object and
you are satisfied with the cutting distance over onto adjacent level areas.
Once complete, walk back along the perimeter and add in wire pegs to those areas of the wire where it is
not pulled down below the level of the grass tips and close to ground level.
