Automatic-Reversing Fan Cycle; Operating Tips - Toro Groundsmaster 5900 Operator's Manual

Automatic-Reversing Fan
Cycle
The hydraulic-fan speed is controlled by hydraulic-fluid
temperature. The radiator-fan speed is controlled
by the engine-coolant temperature. A reverse cycle
automatically initiates both fans when either the
engine coolant or hydraulic-fluid temperature reaches
a certain point. This reversal blows debris off the
screens, lowering the engine and hydraulic-fluid
temperatures (Figure 67). Additionally, the radiator
fans perform a reverse cycle every 21 minutes
regardless of the coolant temperature.

Operating Tips

Operating the Machine
•
Start the engine and run it at the
until it warms up. Move the engine-speed switch
to H , lift the cutting units, disengage the
IGH IDLE
parking brake, press the forward traction pedal,
and carefully drive to an open area.
•
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 or press down on the reverse
EUTRAL
pedal.
Note:
When going downhill in the machine, you
may need to use the reverse pedal to stop.
•
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.
•
Always drive slowly in rough areas.

Changing Mowing Patterns
Change mowing patterns often to minimize a poor
after-cut appearance from repeatedly mowing in the
same direction.
Understanding Counterbalance
The counterbalance system maintains hydraulic
back pressure on the cutting unit lift cylinders.
This pressure improves traction by transferring the
cutting unit weight to the mower-drive wheels. 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
g010392
poor after-cut appearance. Refer to the machine
Service Manual for your traction unit for instructions to
adjust the counterbalance pressure.

If an obstacle is in the way, lift the cutting units to
mow around it.
When transporting the machine from 1 work area
to another, shut off the PTO, raise the cutting
units to the fully upward position, press the
mow/transport switch to the T
engage the transport latches, and place the throttle
in the F position.
AST
To begin cutting, engage the cutting units, then
approach the mowing area slowly.
To achieve the professional straight-line cut and
striping that is desirable for some applications, find
a tree or other object in the distance and drive
straight toward it.
As soon as the front cutting units reach the edge
of the mowing area, perform a teardrop-shaped
turn to quickly line up for your next pass.
Bolt-in mulching baffles are available for the
cutting units. The mulching baffles perform well
when you maintain turf on a regular schedule
to avoid removing more than 25 mm (1 inch) of
growth per cutting. When you cut too much growth
with the mulching baffles installed, the after-cut
