Hydrostatic transmission
Drive down slopes with your foot o the drive
pedal (see 4.32) to use the braking eect of
the hydrostatic transmission when the trans-
mission is not engaged.
5.6 SUGGESTIONS FOR MAINTAINING A
NICE LAWN
1. To keep a lawn green and soft with a good
appearance, it should be cut regularly with-
out damaging the grass. A lawn can be com-
posed of dierent 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 (clover and daisies,
etc.).
2. It is always better to cut the grass when dry.
3. The cutting means 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 rela-
tion to the rate of growth of the grass, which
should not be left to grow too much between
one cut and the next.
6. During hot and dry periods, the grass should
be cut a little higher to prevent the ground
from drying out.
7. The best height of the grass on a well-kept
lawn is approx. 4-5 cm. and with one mowing,
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 twenty-four hour
period. The rst time with the cutting means
at maximum cutting height, possibly reducing
the cutting width and the second cut at the
height desired. Fig. 5.13)
8. The appearance of the lawn will improve if
you alternate the cutting in both directions
(Fig. 5.14)
9. If the collector system tends to get blocked
with grass, you should reduce the forward
speed as it may be too high for the condi-
tion of the grass. If the problem persists, the
probable causes are either badly sharpened
cutting means or deformed ns.
10. Be very careful when mowing near bushes
or kerbs as these could distort the horizon-
tal position of the cutting-means assembly
and damage its edge as well as the cutting
means.
6. MAINTENANCE
6.1 SAFETY RECOMMENDATIONS
WARNING! You must go to a special-
ized Service Centre or contact your Dealer if
the following are malfunctioning:
– the brake;
– the cutting means engage and disengage
functions,
– switching the drive to forward or reverse
gears.
6.2 ROUTINE MAINTENANCE
The table will help you maintain your machine’s
safety and performance. It summarises the main
interventions to be made and the frequency ap-
plicable to each of them.
The boxes at the side are for you to mark the
date or number of working hours at which the
intervention was made.
