Understanding
Counterbalance
The counterbalance system maintains hydraulic
back pressure on the deck-lift cylinders. This
pressure improves traction by transferring the
mower-deck 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
poor after-cut appearance. Refer to the machine
Service Manual for your traction unit for instructions to
adjust the counterbalance pressure.
Using the Brake Pedals
Important:
In emergency braking situations,
remove your foot from the traction pedal and then
press the brake pedals.
In the low speed range only, you can use the brakes
individually for turning or to improve traction. Perform
the following when using the brakes individually:
•
Disconnect the pedal-locking latch
•
For turning assist, press the corresponding brake
pedal to the side you are turning. This allows a
tighter turning radius.
Note:
Use the individual brakes carefully,
especially on soft or wet grass, because the turf
may be torn accidentally.
•
For traction assist, apply light pressure to the
brake pedal corresponding to the front tire that is
slipping. For example, in some slope conditions,
the uphill wheel slips and loses traction. If this
situation occurs, press the uphill brake pedal
gradually and intermittently until the uphill wheel
stops slipping, This action increases the traction
on the downhill wheel.
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
Performing a Fan-Reverse
Operation
The machine-fan speed is controlled by the
hydraulic-fluid temperature and engine-coolant
temperature. When the hydraulic fluid or coolant
reaches a certain temperature, a reverse fan cycle
is automatically initiated. This cycle blows debris off
the rear screen and lowers the engine-coolant and
hydraulic-fluid temperatures.
You can complete a manually-initiated reverse cycle
by simultaneously pressing the right and left buttons
on the InfoCenter. It is recommended that you
manually reverse the fan before you leave the work
area or enter the maintenance or storage area.
Understanding Auto Idle
The machine is equipped with auto idle, which
automatically idles the engine when all the following
functions are not used for a pre-determined time as
previously set in the InfoCenter.
