Starting And Shutting Off The Engine; Understanding Smart Power; Reversing Fan Operation; Understanding Auto Idle - Toro Groundsmaster 4000 Operator's Manual

•
Keep all movement on slopes slow and gradual.
Do not suddenly change the speed or direction of
the machine.
•
Do no operate the machine near drop-offs, ditches,
embankments, or bodies of water. The machine
could suddenly roll over if a wheel goes over the
edge or the edge caves in. Establish a safety area
between the machine and any hazard (2 machine
widths).
Starting and Shutting Off
the Engine
Starting the Engine
Important:
Bleed the fuel system if any of the
following have occurred:
•
The engine has shut off due to lack of fuel.
•
Maintenance has been performed upon the fuel
system components.
1. Remove your foot from the traction pedal and
ensure that it is in N
parking brake is engaged.
2. Move the throttle control to the low idle position.
3. Turn the ignition key to the R
glow indicator should light.
4. When the glow indicator dims, turn the ignition
key to the S
TART
Important:
Do not run the starter motor
more than 15 seconds at a time or premature
starter failure may result. If the engine fails
to start after 15 seconds, turn the key to
the O position, check the controls and
FF
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 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
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 maximum 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 the hydraulic-fluid
temperature and engine-coolant temperature. A
reverse cycle is automatically initiated when either the
engine coolant or hydraulic-fluid temperature reaches
a certain point. This reversal helps blow debris off the
rear screen and lower the engine and hydraulic-fluid
temperatures. By simultaneously pressing the right
and left buttons on the InfoCenter, the fan completes
a manually-initiated reverse cycle. Reverse the fan
manually prior to leaving the work area, entering the
shop, 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,
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 any of the above functions are initiated,
the machine automatically returns to the previous
throttle position.
