Note:
The InfoCenter displays "traction denied"
and the machine should not move. If the
machine does move, there is a malfunction in
the interlock system. Correct this malfunction
before operating the machine.

Breaking in the Machine

To ensure that optimum performance of the parking
brake system is met, burnish (break-in) the brakes
before use. Set the forward traction speed to 6.4 km/h
(4 mph) to match the reverse traction speed. (All 8
spacers moved to the top of the mow speed control.)
With the engine at high idle, proceed forward with the
mow speed control stop engaged and ride the brake
for 15 seconds. Proceed backward at full reverse
speed and ride the brake for 15 seconds. Repeat
this 5 times waiting 1 minute between each forward
and reverse cycle to avoid overheating the brakes.
You may need to adjust the brakes after breaking in
the machine; refer to Adjusting the Parking Brakes
(page 53).

Selecting a Blade

Standard Combination Sail
This blade was designed to provide excellent lift and
dispersion in almost any condition. If more or less lift
and discharge velocity is required, consider a different
blade.
Attributes: Excellent lift and dispersion in most
conditions.
Angled Sail
The blade generally performs best in lower heights of
cut– 1.9 to 6.4 cm (3/4 to 2–1/2 inches).
Attributes:
•
Discharge remains more even at lower heights of
cut.
•
Discharge has less tendency to throw left and thus
a cleaner look around bunkers and fairways.
•
Lower power requirement at lower heights and
dense turf.
Atomic Blade
This blade was designed to provide excellent leaf
mulching.
Attributes: Excellent leaf mulching
Changing the
Counterbalance Settings
During different times of the mowing season or when
turf conditions vary, the amount of counterbalance
(upward lift) required on the cutting decks can be
changed to meet the conditions.
1. Position the machine on a level surface, lower
the cutting decks, shut off the engine, engage
the parking brake, and remove the key from the
ignition switch.
2. In the InfoCenter Settings Menu, scroll down to
Counterbalance.
3. Press the right button to select counterbalance
and change between the low, medium, and high
settings.
Note:
Once the adjustment has been
completed, move the machine to a test area and
operate the machine with the new setting. The
new counterbalanced setting may change the
effective height of cut.

The Diagnostic Light

The machine is equipped with a diagnostic, light which
indicates if the machine detects a malfunction. The
diagnostic light is located on the InfoCenter, above

briefly to indicate that the light is working properly.
When a machine advisory message displays, the light
will illuminate when the message is present. When a
fault message is displayed, the light blinks until the
fault is resolved.
