Starting and Stopping the
Engine
Important: The fuel system will automatically bleed
itself when any of the following situations occur:
•
Initial start up of a new machine.
•
The engine has ceased running due to lack of fuel.
•
Maintenance has been performed upon the fuel system
components.
1. Ensure that the parking brake is set. Remove your foot
from the traction pedal and ensure that it is in neutral.
2. Turn the ignition key to the Run position.
3. When the glow indicator dims, turn the ignition key
to the Start position. Release the key immediately
when the engine starts and allow it to return to the
Run position. Allow engine to warm up at mid speed
(without load), then move the throttle control to the
desired position.
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 Off position,
recheck the controls and procedures, wait 30
additional seconds, and repeat the starting
procedure.
4. To stop the engine, move the PTO switch to the Off
position, set the parking brake, return the throttle
setting to low idle and rotate the ignition key to Off.
Remove the key from the switch to prevent accidental
starting.
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.
Smart Power
With Toro Smart Power™, the operator does not have
to listen to the engine speed in heavy conditions. Smart
Power prevents bogging down in heavy turf by automatically
controlling the machine speed and optimizing cutting
performance. The operator can simply set a max ground
speed, that is comfortable, and mow without having to
manually reduce the traction speed when mowing in heavy
conditions.
Reversing Fan Operation
The fan speed is controlled by hydraulic oil temperature and
engine coolant temperature. A reverse cycle is automatically
initiated when either the engine coolant or hydraulic oil
temperature reaches a certain point. This reversal will help
blow debris off the rear screen and lower the engine and
hydraulic oil temperatures. By simultaneously pressing the
right and left buttons on the InfoCenter, the fan will complete
a manually initiated reverse cycle. It is recommended to
manually reverse the fan prior to leaving the work area,
entering the shop or storage area.
Auto Idle
The machine is equipped with auto idle which automatically
idles the engine when all of the following functions are
not used, for a pre determined time, previously set in the
InfoCenter.
•
The traction pedal is returned to the neutral position
•
The PTO is disengaged
•
None of the lift switches are activated
When any of the above functions are initiated, the
machine will automatically return to the previous throttle
position.
Cruise Control
The cruise control switch locks in the pedal position to
maintain the desired ground speed. Pressing the rear of the
switch turns off the cruise control, the middle position of the
switch enables the cruise control function and the front of
the switch sets the desired ground speed.
Note: Pressing either brake pedal or moving the traction
pedal into the reverse position, for one second, will also
disengage the pedal position.
Engine Speed Switch
The engine speed switch has two modes to change the engine
speed. By momentarily tapping the switch, the engine speed
can be increased or decreased in 100 rpm increments. By
holding the switch down the engine will automatically move
to High or Low idle, depending on which of the switch is
depressed.
Mow Speed
Supervisor (Protected Menu)
Allows the supervisor to set the machine's maximum mowing
speed, in increments of 50%, 75% or 100%, at which the
operator can mow (low range).
Refer to Using the InfoCenter LCD Display, in the Operation
section of this manual, for the procedure to set the mow
speed.
Operator
Allows the operator to adjust the machine's maximum mowing
speed (low range), within the supervisors pre-adjusted
settings. When in the InfoCenter splash or main screen, press
the middle button (
Note: When switching between low and high ranges, the
settings will transfer based on the previous setting. The
settings are reset when the machine is turned off.
