Starting The Engine; Shutting Off The Engine; Cutting Grass With The Machine - Toro Groundsmaster 4500-D Operator's Manual

•
Operate the machine at a lower speed when you
are on a slope.
•
If you feel uneasy operating the machine on a
slope, do not do it.
•
Watch for holes, ruts, bumps, rocks, or other
hidden objects. Uneven terrain could overturn the
machine. Tall grass can hide obstacles.
•
Choose a low ground speed so you will not have
to stop or shift while on a slope.
•
A rollover can occur before the tires lose traction.
•
Avoid operating the machine on wet grass. Tires
may lose traction; regardless if the brakes are
available and functioning.
•
Avoid starting, stopping, or turning the machine
on a slope.
•
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 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 key to the R
indicator should light.
4. When the glow indicator dims, turn the key to
the S position.
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 key to the O
5. Remove the key to prevent accidental starting.
Cutting Grass with the
Machine
Note:
Cutting grass at a rate that loads the engine
promotes DPF regeneration.
1. Move the machine to the job site.
2. Whenever possible, set the engine-speed switch
to high idle.
3. Engage the PTO switch.
4. Gradually move the traction pedal forward and
slowly drive the machine over the mowing area.
5. Once the front of the cutting units are over the
mowing area, lower the cutting units.
6. Cut grass so that the blades can cut and
discharge clippings at a high rate while
producing a good quality of cut.
Note:
If the cutting rate is too high, the quality
of cut may deteriorate. Reduce the ground
speed of the machine or reduce the width of cut
to regain high idle engine speed.
7. When the cutting units are over the far edge of
the mowing area, lift the cutting units.
8. Perform a tear-shaped turn to quickly line up for
your next pass.
