10.2 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.
The decomposing clippings return organic
nutrients to the soil, serving as a natural
fertiliser and slowing down weed growth.
To ensure a perfect, thick lawn, mulch
regularly and keep the grass short.
Mulching should be done at least twice a
week in the main period of growth (spring)
and at least once a week in the summer
and autumn.
Mulching procedure:
VIKING recommends mulching only when
the lawn is dry and the grass is not too
high.
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.
In high grass, the lawn must be mowed in
two stages:
First stage – the lawn is mowed at the
maximum cutting height.
Second stage – 12 to 24 hours after the
40
first stage, mulch the lawn to the desired
grass height at right angles to the first
mowing direction.
10.3 Working area for operator
● For safety reasons, the operator
must stay within the working area
behind the handlebar when starting the
engine and when the engine is running.
Always observe the safety distance
provided by the handlebar.
● The lawn mower must only be operated
by one person. Other persons must
keep out of the danger area. (

setting if the engine is difficult to
start.
Thanks to the fixed throttle setting,
the engine always operates at the
optimum working speed after
starting.
