Grass Cutting - EMAK MISTRAL 72/13 H Manual De Uso

before the engine can be restarted.
Moving without mowing
GB WARNING: This machine has not been approved for
use on public roads. It must be used (as indicated by
the highway code) in private areas closed to traffic.
CAUTION: When moving on level ground, the blade
must be disengaged and the cutting deck put at its
highest position (position 7). When moving up or down a
slope, the cutting deck must be put at its lowest position
to ensure maximum stability of the machine.
Put the accelerator control between the "SLOW" and "FAST"
positions; disengage the parking brake by moving the brake
lever to the right.
Move the accelerator lever in the "FAST" direction and go to
the required speed using the accelerator and the forward
speed adjustment pedal. The pedal must be depressed
gradually, since a sudden engagement of drive to the wheels
may cause tipping and loss of control of the machine.
Braking
To brake, simply take your foot off the speed adjustment
pedal that you are using. The machine will come to a standstill
in a few seconds.
WARNING: Do not brake by using the opposite speed
adjustment lever with respect to the direction of
travel. For example: do not press the reverse speed
adjustment pedal when travelling forward.
Reversing
Move the accelerator lever in the "FAST" direction and go to
the required speed using the accelerator and the reverse
speed adjustment pedal. The pedal must be depressed
gradually, since a sudden engagement of drive to the wheels
may cause you to lose control of the machine.

6.3 Grass Cutting

Grass cutting can be carried out in forward drive and in
reverse drive.
Grass cutting in forward drive
Blade engagement and forward movement
When you have reached the area to be mowed:
- put the accelerator into the "FAST" position;
- engage the blade by pushing the button to the "START"
position;
- to start moving, operate the speed regulation controls,
taking care to depress the pedal very gradually and with
particular caution as already described. In this way the
machine's ground speed will adapt to the conditions of the
lawn gradually and progressively. Always engage the blade
with the cutting deck in the highest position, then gradually
lower to the height required. To achieve good collection
and even cutting of the grass, choose a forward speed to
suit the quantity of grass to be cut (height and density) and
the lawn's humidity.
The speed should always be reduced if you note a reduction
in engine speed, since a forward speed that is too high will
not cut the grass well.
28
Disengage the blade and put the cutting deck in the highest
position whenever you need to get past an obstacle.
Grass cutting in reverse drive
Blade engagement and reverse movement
To enable the machine to mow in reverse drive, the following
operations must be performed:
1. bring the machine to a standstill
2. disengage the blade drive (STOP pos.)
3. turn the ignition key from position 1 (on) to position R
(reverse mowing)
4. engage the blade drive (START pos.)
5. start mowing in reverse drive
Use the reverse mowing enable function only if strictly
necessary.
Follow the instructions in the above paragraph "Grass cutting
in forward drive".
Cutting height adjustment
The cutting height is adjusted by moving the lever (G, Fig.10)
with 7 height positions.
Adjusting the grass-catcher full sensor
The grass-catcher full sensor can be adjusted in two positions
using the screw (A, Fig.12):
1) The sensor is more sensitive with the rod fully exposed; this
position is recommended for mowing dry grass.
2) The sensor is less sensitive with the rod fully inserted; this
position is recommended for mowing wet grass.
Emptying the grass-catcher
This operation can only be performed with the blade
disengaged, otherwise the engine stops. When the grass-
catcher is full an audible warning is given. Stop forward
movement in order not to block the collector channel, and
disengage the blade which will stop the audible signal. Empty
the grass-catcher by lifting it using the handle. At times the
audible warning may be heard on engaging the blade, even
when the grass-catcher has been emptied. This is due to grass
cuttings left on the sensor of the micro-switch. To stop the
signal, either remove the remaining grass or disengage the
blade and then immediately engage it again.
Sloping ground
See paragraph Using the machine on sloping ground on
page 26.
Side discharge
If you prefer the cuttings to be discharged onto the ground
rather than collected, the machine is supplied with a side
discharge kit.
The kit consists of two parts, one made of metal (A, Fig.14)
and the other made of plastic (B), which must be assembled
together using the 3 bolts (C) and corresponding nuts and
washers. Line up the square holes with the bolts, inserting the
bolts from inside.
The assembled kit must be inserted in the appropriate
compartment of the cutting deck, after having removed the
safety cotter pin (D) and released the catch (E) to open the
