Understanding The Operating Characteristics Of The Machine; Operating The Engine-Cooling Fan - Toro Groundsmaster 4500-D Operator's Manual

CAUTION
Checking the machine for oil leaks, loose
parts, and other malfunctions while the engine
is running may bring you in close contact with
hot or moving parts of the machine, causing
injury.
Shut the engine off and wait for all moving
parts to stop before checking for oil leaks,
loose parts, and 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
turbo charger to cool down before shutting the engine
off.
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 PTO switch to the O
2. Set the parking brake.
3. Return the engine low idle.
4. Turn the key in the ignition switch to the O
and remove the key.
Understanding the Operating
Characteristics of the Machine
Practice driving the machine because it has a hydrostatic
transmission and its characteristics are different than many
turf maintenance machines. Some points to consider when
operating the machine and mower decks are the transmission,
engine speed, load on the cutting blades and the importance
of the brakes.
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.
Another characteristic to consider is the operation of the
pedals that are connected to the brakes. The brakes can be
used to assist in turning the machine. However, use them
carefully, especially on soft or wet grass because the turf
may be torn accidentally. Another benefit of the brakes is to
maintain traction. For example, in some slope conditions, the
uphill wheel slips and loses traction. If this situation occurs,
depress the uphill turn pedal gradually and intermittently until
the uphill wheel stops slipping, thus, increasing traction on
the downhill wheel.
Use extra care when operating the machine on slopes. Make
sure that the seat latch is properly secured and the seat belt
position.

is buckled. Drive slowly and avoid sharp turns on slopes to
prevent rollovers. For steering control, the mower decks it
must be lowered when going downhill.
Important: Allow engine to idle for 5 minutes before
shutting it off after a full load operation. This allows the
turbo charger to cool down before shutting the engine
off. Failure to do so may lead to turbo-charger trouble.
Before stopping the engine, disengage all controls and set
the engine speed to Slow. Setting the engine speed to Slow
reduces high engine rpm, noise, and vibration. Turn the key in
the ignition switch to the O
Operating the Engine-Cooling
Fan
The engine cooling fan is normally controlled by the machine.
The machine has the ability to reverse the fan to blow debris
off the rear screen. Under normal operating conditions
the machine controls the fan speed and direction based
on coolant and hydraulic-fluid temperature, and the fan
automatically reverses direction to blow debris off the rear
screen. A reverse cycle is automatically initiated when either
the coolant or hydraulic-fluid temperature reaches a specific
temperature.
You can manually reverse the fan by pressing the 2 outer
buttons of the InfoCenter for 2 seconds—the fan completes
a manually initiated reverse cycle. Reverse the fan when the
rear screen is clogged or prior to moving the machine into the
shop or a storage area.
