Mowing Technique - Husqvarna Automower 305 Technical Manual

1.7 Mowing technique

The mowing system is based on an efficient and
energy saving principle. Unlike many conventional
lawnmowers, the robotic lawnmower cuts the grass
instead of knocking it off.
1.7.1 Mowing in different weather
conditions
Rain
It is recommended to allow the robotic lawnmower to
mainly mow in dry weather to obtain the best possible
result. The robotic lawnmower can also mow in the
rain, however, wet grass easily sticks on the mower
and there is a greater risk of slipping on steep slopes.
Thunder
If there is a risk of thunder, all connections to the
charging station must be disconnected. This is done
to avoid damage to the circuit board in the charging
station.
1.7.2 Blades
It is important to have sharp, well-maintained blades
on a robotic lawnmower, more important than on a
conventional lawnmower. This is due to the principle
of cutting the grass instead of knocking it off. The life
of the blades is increased as a result of the double-
ground blades in conjunction with the technology that
rotates the blade disc in both directions.
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.
Worn blades should not be sharpened or whetted.
This is to prevent the mowing system from becoming
imbalanced.
Poor or dull blades can result in the grass bending
instead of being mown, the tops become frayed and
the mower may find it difficult to mow a large working
area.
1. FUNCTION
All blades and screws must be replaced at the same
time to ensure the mowing system is balanced.
Blades are available in several different types and
are sold in various quantities. Use only approved
original blades from the Husqvarna Group. From the
start of 2011, these are marked with a Husqvarna or
GARDENA symbol.
1.7.3 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
lawnmower.
