Mowing technique
The cutting system in the Husqvarna robotic lawnmower
is based on an efficient and energy saving principle.
Unlike many standard lawnmowers, the robotic
lawnmower cuts the grass instead of knocking it off.
We recommend you allow the robotic lawnmower to
mainly mow in dry weather to obtain the best possible
result. Husqvarna's robotic lawnmowers can also mow
in the rain, however, wet grass easily sticks on the robotic
lawnmower and there is a greater risk of slipping on steep
slopes.
The blades must be in good condition to obtain the best
mowing result. In order to keep the blades sharp for as
long as possible it is important to keep the lawn free
from branches, small stones and other objects which
can damage the blades.
Replace the blades regularly for the best mowing result.
It is very easy to replace the blades. See 8.7 Blades on
page 74.
Working method
The robotic lawnmower automatically mows the lawn.
It continuously alternates between mowing and charging.
The robotic lawnmower starts to search for the charging
station when the battery charge becomes too low. The
robotic lawnmower does not mow when it is searching for
the charging station.
When the robotic lawnmower is searching for the
charging station, it can find it in a number of different
ways. See Finding the charging station on page 13.
When the battery is fully charged, the robotic lawnmower
will leave the charging station and start mowing in a place
in the garden where it has not been lately. The place is
decided by the built-in GPS-receiver. This function is for
Automower 330X only. For Automower
®
have to set manual exit settings to make sure that the
lawn will be cut evenly, see "Installation" on page 49.
When the robotic lawnmower body hits an obstacle, the
robotic lawnmower reverses and selects a new direction.
Sensors at the front and back will sense when the robotic
lawnmower is approaching the boundary wire. The
robotic lawnmower travels up to 32 centimetres beyond
the wire before it turns around.
