2. Move the engine-speed switch to the L
position.
3. Turn the ignition key to the R
Note:
The glow-plug indicator illuminates.
4. When the glow indicator dims, turn the ignition
key to the S
TART
immediately when the engine starts and allow it
to return to the R
Important:
Do not run the starter motor
more than 30 seconds at a time or premature
starter failure may result. If the engine fails
to start after 30 seconds, turn the key to
the O position, check the controls and
FF
procedures, wait 30 additional seconds, and
repeat the starting procedure.
5. Allow engine to warm up at mid speed (without
load), then move the throttle control to the
desired position.
Important:
Allow engine to idle for 5 minutes
before shutting it off after a full-load operation.
Failure to do so may lead to turbo-charger trouble.

Shutting Off the Engine

Important:
Allow the engine to idle for 5 minutes
before shutting it off after a full-load operation.
This allows the turbocharger to cool down before
shutting off the engine. Failure to do so may lead
to turbocharger trouble.
Note:
Lower the mower decks to the ground
whenever machine is parked. This relieves the
hydraulic load from the system, prevents wear on
system parts, and also prevents accidental lowering
of the mower decks.
1. Move the throttle control backward to the S
position.
2. Move the PTO switch to the O
3. Engage the parking brake.
4. Rotate the ignition key to the O
5. Remove the key from the switch to prevent
accidental starting.
Understanding Smart
Power® Traction
With the Smart Power® function, you do not have
to listen to the engine speed in heavy conditions.
This function prevents bogging down in heavy turf
by automatically controlling the machine speed
and optimizing cutting performance. You can set a
comfortable maximum ground speed and mow without

Performing a Fan-Reverse
Operation
The machine-fan speed is controlled by the
hydraulic-fluid temperature and engine-coolant
temperature. When the hydraulic fluid or coolant
reaches a certain temperature, a reverse fan cycle
is automatically initiated. This cycle blows debris off
the rear screen and lowers the engine-coolant and
hydraulic-fluid temperatures.
You can complete a manually-initiated reverse cycle
by simultaneously pressing the right and left buttons
on the InfoCenter. It is recommended that you
manually reverse the fan before you leave the work
area or enter the maintenance or storage area.

Understanding Auto Idle

The machine is equipped with auto idle, which
automatically idles the engine when all the following
functions are not used for a pre-determined time as
previously set in the InfoCenter.
•
The traction pedal is returned to the
position.
•
The PTO is disengaged.
•
None of the lift switches are activated.
When you initiate any of the above functions, the
machine automatically returns to the previous
throttle position.

Using the Cruise Control

LOW
The cruise-control switch locks in the pedal position
to maintain the desired ground speed. Pressing the
rear of the switch turns cruise control off, the middle
position of the switch enables the cruise-control
function, and the front of the switch sets the desired
ground speed.
Note:
Pressing the brake pedal or moving the traction
pedal into the reverse position, for 1 second, shuts
off the cruise control.
Diesel Particulate Filter
Regeneration
The diesel particulate filter (DPF) is part of the exhaust
system. The diesel-oxidation catalyst of the DPF
reduces harmful gasses and the soot filter removes
soot from the engine exhaust.
