1.6.3 Irregular mowing pattern
The robotic lawnmower mows the lawn in an irregular
pattern. This gives a very even mowing result. In addition,
there are no distinctive tracks left in the lawn, which is
often the case when using a conventional lawn mower.
Spiral cutting
(Only for Husqvarna Automower® 310/315)
Sometimes the robotic lawnmower can change the
mowing pattern and start to mow in a spiral pattern
instead. This is called spiral cutting. The purpose of
spiral cutting is to quickly get the same length of grass
over the entire working area.
When the robotic lawnmower starts spiral cutting this
means it has perceived the lawn in an area to be longer
and/or thicker than before. The length/thickness of the
lawn in this area does not need to differ that much from
the other areas for the robotic lawnmower to start spiral
cutting. Sometimes the difference is hardly visible.
The robotic lawnmower always attempts to keep the
blade disc at an even speed. Different degrees of power
are used for this depending on the length/thickness
of the grass. The robotic lawnmower compares the
instantaneous power with an average power value from
the latest hours of mowing. This means that, when the
robotic lawnmower enters an area where the lawn is
longer/thicker than before, the instantaneous power
will differ from the average power and the robotic
lawnmower will then start spiral cutting.
The factory setting for Intensity is Medium for the robotic
lawnmower to begin spiral cutting. Intensity can be
set between Low/Mid/High using the Settings - Spiral
cutting menu. It is also possible to entirely shut down
the spiral cutting function in this menu. The Low setting
means that the robotic lawnmower begins spiral cutting
less often.
Spiral cutting is only activated in the automatic
operating position, i.e. the Main area mode. Mowing in
the Secondary area mode does not allow the robotic
lawnmower to begin spiral cutting.
