5.5.2 Cutting height adjustment
The height is adjusted by moving the lever with 7 height positions
( 4.7).
5.5.3 Lawn maitenance
1. To keep a lawn green, soft and attractive, it should be cut regu-
larly without damaging the grass. A lawn can be composed of
different types of grass. If the lawn is cut frequently, grass and
roots grow more vigorously, forming a solid grassy bed.
If the lawn is cut is less frequently, higher grass and weeds start
growing (plus daisies and clovers, etc.).
2. It is always better to cut the grass when dry.
3. The blades must be in good condition and well sharpened so
that the grass is cut straight without a ragged edge that leads to
yellowing at the ends.
4. The engine must run at full speed, both to ensure a sharp cut of
the grass and to get the necessary thrust to push the cuttings
through the collector channel.
5. The frequency of mowing should be in relation to the rate of
growth of the grass. The grass should not be left to grow too
much between one cut
and the next.
6. During hot and dry peri-
ods, the grass should be
cut a little higher to pre-
vent the ground from
drying out.
7. The best height of the
grass on a well-kept
lawn is approx. 4-5 cm.
With one cut, you do not
need to remove more
than a third of the total
height.
If the grass is very tall, it
should be cut twice in a

5.5.4 Slopes
Complying with the slope li-
mits already mentioned,
lawns on a slope have to mo-
wed moving up and down
and never across them, tak-
ing great care when chang-
ing direction that the first
wheels do not hit obstacles
(such as stones, branches,
roots, etc.), that may cause the machine to slide sideways, roll over
or otherwise cause loss of control.
OF DIRECTION ON SLOPES and always engage the parking
brake before leaving the machine stopped and unattended.

twenty-four hour period - the first time with the blades at maxi-
mum height, possibly reducing the cutting width, and the sec-
ond cut at the desired height.
The appearance of the lawn will improve if you alternate cutting
in both directions.
If the collector system tends to get blocked with grass, you
should reduce the forward speed as it may be too high for the
condition of the grass. If the problem persists, the probable
causes are either badly sharpened blades or deformed wings.
