Understanding the
Acceleration Mode
This setting determines how quickly the machine
changes traction speed, and effects the deceleration
of the machine in the low speed range. Enter the
protect menus in the InfoCenter to change the
acceleration mode. The acceleration mode has the
following 3 positions:
•
Low—low acceleration and deceleration
•
Medium—medium acceleration and deceleration
•
High—highest acceleration and deceleration
Understanding the
Turnaround Mode
The turnaround mode allows you convenient, 1-touch
control to raise the cutting units above the turf while
temporarily stopping the blades, allowing you to focus
on driving the machine at the end of a mowing pass,
or while navigating other obstacles.
Note:
The turnaround mode is a feature in the
protected settings.
•
When the turnaround mode is set to the O
position, you momentarily press the lift switch
rearward (Figure 11) to automatically raise all
cutting units from the float position to a preset
height, automatically disengaging the PTO. To
resume mowing, press the lift switch forward. All
the cutting units lower, and the PTO starts again.
•
When the turnaround mode is set to the O
position, you manually raise the cutting units
from the float position by pressing and holding
all lift switches rearward until the cutting units
raise to the desired height. For Groundsmaster
4700 machines, press all 3 lift switches to raise
all 7 cutting units (Figure
disengage until the cutting units raise to the same
preset height to which the cutting units raise when
the turnaround-mode is set to O
Note:
By default, the turnaround mode is O
Understanding
Counterbalance
The counterbalance system maintains hydraulic
back pressure on the cutting-unit lift cylinders. The
counterbalance system monitors the real-time traction
pressure, dynamically changing the lift-cylinder back
pressure to optimize traction capability and after-cut
appearance. The counterbalance pressure has been
set at the factory to an optimal balance of after-cut

appearance and traction capability in most turf
conditions. Decreasing the counterbalance setting can
produce a more stable cutting unit but can decrease
the traction capability. Increasing the counterbalance
setting can increase the traction capability, but
may result in a poor after-cut appearance; refer to
Accessing Protected Menus (page
The customizable counterbalance setting controls are
as follows:
•
Low—the most amount of weight on cutting units
and the lowest weight on the drive wheels
•
Medium—medium weight on cutting units and the
drive wheels
•
High—the least amount of weight on cutting units
and the highest weight on machine drive wheels
Understanding Toro Smart
Power™
With Smart Power, the operator does not have to
listen to the engine speed in heavy load conditions.
Smart Power prevents the engine from bogging
down in heavy cutting conditions by automatically
controlling the machine speed and optimizing cutting
performance.
Note:
By default, the Smart Power feature is O

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

2. Turn the key to the R

3. 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.
4. Release the key immediately when the engine
starts and allow it to return to the R
