Cutting 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 scything 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.
Replace the blades regularly for the best mowing result.
It is very easy to replace the blades. Refer to 8.7 Blades
page 78.
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.
While searching for the charging station, the robot
lawnmower can find it in a number of different ways, see
Finding the Charging Station on page 14.
Once the battery is fully charged, the robot lawnmower
will leave the charging station and start to mow an area
of lawn where it has not recently been. This area will
be determined by the GPS receiver. This functionality
applies to Automower
®
Manual exit settings may be needed on the Automower
420 in order to ensure the lawn is evenly mown, see 6.8
Installation on page 51.
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 centimeters beyond
the wire before it turns around.
