starter failure may result. If the engine fails
to start after 15 seconds, turn the key to
the O position, check the controls and

procedures, wait 15 additional seconds, and
repeat the starting procedure.
5. Release the key immediately when the engine
starts and allow it to return to the R
6. Move the throttle control to the desired position.
When the temperature is less than -7°C (20°F),
the starter motor can be run for 30 seconds on
then 60 seconds off for 2 attempts.
Important:
Shut off the engine and allow the
engine to cool before you check for oil leaks,
loose parts, or other malfunctions.

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 cutting units 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 cutting units.
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
having to manually reduce the traction speed when
you mow in heavy conditions.
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.

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.
The DPF regeneration process uses heat from the
engine exhaust to incinerate the soot accumulated on
the soot filter, converting the soot to ash, and clears
the channels of the soot filter so that filtered engine
exhaust flows out the DPF.
The engine computer monitors the accumulation of
soot by measuring the back pressure in the DPF. If
the back pressure is too high, soot is not incinerating
in the soot filter through normal engine operation. To
keep the DPF clear of soot, remember the following:
