A perfect, thick lawn is achieved by
– Mowing at high speed (throttle lever in
MAX position) and a slow driving
speed.
– Regular mowing and keeping the grass
short.
– Not cutting the lawn too short in hot, dry
conditions as it will be burnt by the sun
and become unsightly.
– Using sharp mowing blades. Mowing
blades should therefore be regularly
sharpened or replaced.
– Changing the cutting direction.
Mowing tall grass
If the grass is very high, it is better to mow
it in two stages:
– use the highest cutting height,
maximum engine speed and slow
driving speed for the first mowing
operation;
– for the second mowing operation, select
the desired cutting height and set the
maximum engine speed. Adjust the
driving speed to the condition of the
lawn.
Preventing blockage of the discharge
chute
If the discharge chute becomes blocked
with grass, reduce the driving speed. This
may be too high in relation to the lawn
conditions. Pull out the slide of the level
sensor fully. (Ö 8.19)
If the problem persists, the probable cause
is damaged or worn wings on the mowing
blades. Replace the mowing blades.
(Ö 15.13)
Clean the mowing deck, discharge chute
and mowing blades after each use to
prevent the accumulation of grass
deposits. (Ö 15.2)
Fertilisation
Mowing the grass deprives the ground of
permanent nutrients, which can be
returned by using a high-grade, long-term
lawn fertiliser. Usually, fertilising three
times per mowing season is necessary.
For this purpose, the lawn should be dry,
so that the fertiliser does not stick to the
grass blades and burns them. It is then
better to water the lawn, which results in
the fertiliser being flushed off the grass
blades. (Observe manufacturer's
instructions for use.)
Natural fertilising is possible using lawn
clippings. This is made possible by the use
of the mulching kit. The mulching kit is
available as a special accessory and is not
included in the standard equipment.
(Further information is available from your
STIHL specialist dealer.)
Ground-conserving working
The most important factors for ground-
conserving working are operating
technique and ground moisture.
In order to achieve clean mowing results,
the driving speed must be adapted to the
condition of the grass to be mowed (height
and density) and to the moisture of the
lawn.
Executing curves that are too tight
increases the loading on the turf and leads
to poor mowing results, particularly on wet
grass, as the wheels sink into the soft
grass.
The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
Note
Check the mowing deck for correct
installation position before starting
work.
Select a flat, even area for initial
use of your machine and mow in
straight and slightly overlapping
strips for practising purposes.
Grass should always be mowed
when dry.
Warning – fire hazard!
Avoid overloading the mowing deck
drive. Overloading may lead to
constant slipping of the V-belt and
consequently to a fire hazard due to
overheating.
Unusual running noise, e.g. a
"squealing" (slipping noise) of the
V-belt, indicates overloading. For
this reason, never mow in high
grass when the discharge chute is
blocked or the grass catcher box is
full; use a mulching kit (special
accessory) if necessary.
The mowing deck, particularly the
V-belt area, must always be kept
free of combustible material (grass,
leaves, etc.). It should also be
cleaned regularly to prevent a fire
hazard.
12. Safety devices
Risk of injury!
If a safety device is found to be
defective, the machine must not be
operated. Consult a specialist
dealer; STIHL recommends STIHL
specialist dealers.
