10.7 General information on mulching
During mulching, the cut grass is chopped
up several times through a special air flow
guidance system in the mower blade area
and then blown back into the turf. The
clippings remain on the lawn.
Benefits
The decomposing clippings return organic
nutrients to the soil, serving as a natural
fertiliser.
Advantages
Emptying the grass catcher box and
disposal of the clippings are dispensed
with. Weed growth is slowed down and
significant amounts of fertilizer are saved.
10.8 When is mulching permissible?
STIHL recommends mulching only when
the lawn is dry and the grass is not too
high.
If the grass is too high, the lawn should be
mowed in two stages. (
10.9)
Caution
If the cutting height is too low or the
grass is wet, the housing may
become clogged, blocking the
blade!

10.9 How should mulching be
performed?
Requirements for good mulching results:
– Set the optimal cutting height: A third of
the grass height should be cut.
– Use well sharpened blades.
– Vary the mowing direction and ensure
that the mowing strips overlap.
Working method in high grass
In high grass, the lawn should be cut in two
stages.
First stage:
The lawn is mowed at the maximum
cutting height.
Second stage:
12 to 24 hours after the first stage, mulch
the lawn to the desired grass height at right
angles to the first mowing direction.
10.10 How often should mulching be
performed?
To ensure a perfect, thick lawn, mulch
regularly and keep the grass short.
Main growth period:
Spring:
mulch at least twice per week.
Summer and autumn:
mulch at least once per week.

These include the housing and correctly
installed handlebar.
11.3 Two-hand operation
The motor can only be switched on by
pressing and holding the ON button with
the right hand and then pulling the
motorstop lever to the handlebar with the

11.4 Motor run-down brake
When the motorstop lever is released, the
mowing blade comes to a standstill in less
than three seconds.
An integrated motor run-down brake
shortens the run-down time until the blade
stops.
