Slopes
The boundary wire can be laid across a slope that
slants less than 10 %.
The boundary wire should not be laid across a slope
that is steeper than 10 %. There is a risk of
Automower finding it difficult to turn there. The mower
will then stop and show the fault message Outside
working area. The risk is at its greatest in damp
weather conditions, as the wheels can slip on the wet
grass.
However, the boundary wire can be laid across a
slope steeper than 10 % when there is an obstacle
that Automower can be permitted to collide with, for
example, a fence or a dense hedge.
Automower can mow areas inside
the working area that slope up to
35 % (see picture). Areas that slope
more must be demarcated by the
boundary wire.
When any part of the working area's
boundary slopes more than 10" per
100", the boundary wire must be
routed about 40" in on flat ground
before the slope starts.
