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

Understanding the
Operating Characteristics
of the Machine
•
This machine has an automotive-style throttle that
is controlled by the traction pedal.
•
This machine does not have a separate throttle
switch or throttle lever.
•
When you remove your foot from the traction
pedal, the machine dynamically brakes to a stop.
•
The pedal controls are optimized to provide a
reactive yet stable response, allowing you to
maintain consistent control over rough terrain,
while still allowing for quick, smooth braking.
•
While transporting, the traction pedal will operate
similar to a car and change the engine and traction
speed dependent on the traction pedal position.
•
When mowing, the engine speed will automatically
raise to high idle.
•
If the engine is at low idle, performing a function
like lifting the cutting units or pressing the traction
pedal raises the engine speed to a minimum
working speed, providing enough power to
efficiently perform the function.
•
Limit the machine idle time as recommended for
diesel particulate filter (DPF) regeneration. Shut of
the machine to prevent extended idling time.
•
The maximum speeds set in the PIN protected
menu settings are set by the supervisor to limit the
machine's maximum traction speed.
•
The achievable traction pedal use, cruise control,
and pedal stop traction speeds are all limited by
the maximum speeds set in the PIN protected
menu.

Operating the Machine

•
When you start the engine and the hydraulic fluid
temperature is low, the engine speed automatically
increases to optimize operation and warms up the
machine. The engine speed automatically returns
to low idle after the hydraulic fluid temperature is
in a normal operating range.
•
Under normal operating conditions, this machine
is intended to operate in the H/L AUTO position
on the speed range switch
position allows the machine to automatically switch
between low and high speed ranges, depending
on whether the machine is being used for mowing
or transporting.
•
When you select the L
range switch (Figure
(Figure 25). This
position on the speed
OW
25), the machine will always
operate in low speed range. This setting is
preferable for operation in a shop area, loading or
unloading from a trailer, climbing steep inclines,
or any other operation where the higher traction
speeds of the high speed range is not desired.
•
If an obstacle is in the way, lift the cutting units to
mow around it.
•
When transporting the machine between work
areas, engage the A
the PTO, and raise the cutting units to the fully
upward position. This allows the traction pedal to
operate like a car.
•
Always drive slowly in rough areas.
Practice Operating the Machine
•
To get familiar with the features of the machine,
practice operating the machine.
•
Lift the cutting units, disengage the parking brake,
press the forward traction pedal, and carefully
drive to an open area.
•
Practice driving the machine, because it has a
hydrostatic transmission and its features can differ
from other turf-maintenance machines.
•
Practice moving forward and reverse, and starting
and stopping the machine. To stop the machine,
remove your foot from the traction pedal and let it
return to N
EUTRAL
Note:
When going downhill in the machine, you
may need to use the reverse pedal to stop.
•
Remove your foot from the traction pedal and
press down on the brake pedals to stop quickly.
•
Practice driving around obstacles with the cutting
units up and down. Be careful when driving
between narrow objects so that you do not damage
the machine or cutting units.
