Passages When Mowing
Long and narrow passages and areas narrower than
1.5-2 meters should be avoided. When the robotic
lawnmower mows there is a risk that it will move around
in the passage or area for too long. The lawn will then
look flattened.
Slopes
The robotic lawnmower can also operate on sloping
working areas. The maximum gradient is defined as
percentage units (%). The slope as a percentage is
calculated as the difference in elevation in centimeters
for every meter. If for instance the difference in elevation
is 15 cm, the slope gradient is 15 %. See the adjacent
picture.
The boundary wire can be laid across a slope that has a
gradient of less than 15 %.
The boundary wire should not be laid across a slope
that is steeper than 15 %. There is a risk that the robotic
lawnmower will find it difficult to turn there. The robotic
lawnmower will then stop and the Outside working area
fault message is displayed. 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 15 % if there is an obstacle that the robotic
lawnmower is allowed to collide with, for example, a fence
or a dense hedge.
Inside the working area the robotic lawnmower can mow
areas which slope up to 45 %. Areas that slope more
must be demarcated by the boundary wire.
When a part of the working area's outer edge slopes more
than 15 %, the boundary wire must be laid about 35 cm in
on the flat ground before the beginning of the slope.
