ADJUSTMENTS
TRACTOR BRAKE ADJUSTMENT
(FIG. 28)
Your tractor is equipped with a disc brake mounted on
the transaxle.
To check the brake operation:
1. Place the tractor on a flat surface, and stop the
engine.
2. Place the shift control lever in neutral position.
3. Depress the brake pedal enough to latch the parking
brake lever in the engaged position (refer to Fig. 14).
4. If you cannot push the tractor, the brake is adjusted
correctly and is functioning.
5. If you can push the tractor, the brake is too loose and
should be tightened.
To adjust loose brake:
1. Place the shift control lever in neutral position,
and depress the brake pedal to latch the parking
brake lever in the engaged position.
2. Turn the brake adjusting nut clockwise until you
cannot push the tractor.
3. Check again the tractor brake adjustment, as
described above.
To adjust tight brake:
1. Place the shift control lever in neutral position.
2. Turn the brake adjusting nut counterclockwise,
until you can push the tractor.
3. Check again the tractor brake adjustment.
While operating the tractor, check the stopping
distance. If the tractor requires more than 1
meter to stop at high speed in the highest gear,
the brake must be adjusted.

THE GRASS COLLECTOR OVERLOAD
WARNING SYSTEM (ZP 98/1 MODEL)
Important note: This system only works in "AUTO"
switch position. (see operations/controls section of
manual).
The grass collector capacity has been designed to hold a
substantial volume of grass.
The overloading of this intended capacity may result in
clogging of the discharge tunnel creating a potentially
hazardous condition. As a safety precaution, the tractor is
equipped with an overload warning system.
As a result of an acumulation of a predetermined volume
of grass clippings an overload protection switch located
inside the grass collector will be mechanically activate.
The signal from this switch is interpreted by the
"SMART CONTROL MODULE" distinguishing
between random impulse actuation which are ignored &
only accepting signals exceed a minimum of 1 second +
to prevent nuisance activation.
An audible warning device "BUZZER" will be activated
providing an intermittent "BEEP" for a 3 second dura-
tion. The cutting system will be automatically switched
off at the end of the "BEEP" cycle indicating that the
grass collector must be emptied prior to continuing
further.
TEST PROCEDURE TO VERIFY
PROPER FUNCTION OF THE
OVERLOAD WARNING SYSTEM
Since this system is considered to be an important safety
feature, it is recommended that the following test
procedure be performed on a regular basis very carefully
following all the necessary safety regulations & precau-
tions.
The battery must be fully charged prior to this test.
The "AUTO-MAN" switch must be in the "AUTO"
position.
Insert the ignition key & start the engine.
Switch on the cutting system.
Manually activate & maintain in this position for the
duration of this test the overload protection switch
located inside the grass collector.
The audible warning "BUZZER" signal cycle should
start after the 1
st second.
After a 3 second period both the "BUZZER" & the
cutting system will stop operating.
The warning system is in functional order if all of the
abov e steps have been complete as indicated above.
Please consult your local dealer if the test procedure
was not completed successfully.
The cutting system can be re-activated after emptying of
the grass collector by either one of the following options:
Activate the "RESET" switch or
Turn of & then on again the switch for the cutting
system engagement.
