OPERATING INSTRUCTIONS
Note:
TORO recommends HIGH RANGE ground
speed be used for road travel only (with cutting units
up).
Points to consider while operating the traction unit,
cutting units or other implements are the hydrostatic
transmission, engine speed, load on the cutting blades
or other implement components and the importance of
the brakes. To maintain adequate power for the
traction unit and implement components while
operating, regulate traction pedal position to keep
engine rpm high and relatively constant. Good rules to
follow are; decrease ground speed as the implement
load increases, and increase ground speed as the load
decreases.
Warning Systems
- If a warning light and audible
warning come on during operation, stop immediately
and correct the problem before continuing. Serious
damage could occur if the machine is operated with an
uncorrected problem. However, if the engine stops
because of overheating, the emergency over-ride
button can be used to operate the engine for short
intervals (Fig. 30).

Mowing
- When approaching area to mow, position
the ground speed selector in LOW RANGE and
release. Switch lever will return to neutral and High
Range light will go out. Move the throttle lever to FAST
and lower the cutting units. Pull the sleeve of the deck
drive PTO switch up, position it in ENGAGE position
and release. Lever will return to neutral position and
PTO will be engaged automatically. Depress traction
pedal slowly to begin cutting operation.
Note:
After lowering mowers, do not allow levers to
snap back to neutral. This could allow the levers to go
past neutral, lock the cutting units in a non-float mode
and prevent them from following turf contours.
Should either outboard cutting unit contact an
immovable object while mowing, the mower lift arm
latch assembly absorbs the impact and breaks away.
This allows the cutting unit to swing rearward. Should
this occur, stop the machine. Fully raise the cutting
unit, then lower it to cutting position. This will allow the
lift arm latch assembly to return to normal
configuration. Be sure to inspect the cutting unit for
damage and repair as necessary before resuming
operation.
Caution:
This product may exceed noise levels of 85
dB(A) at the operator position. Ear protectors are
recommended for prolonged exposure to reduce the
potential of permanent hearing damage.
The individual wheel brakes can be used to assist in
turning the machine. However, use them carefully,
especially on soft or wet turf because it may be torn
accidentally. The brakes are also beneficial to maintain
traction; for example, in some slope conditions, the
uphill wheel may slip and lose traction. If this occurs,
gradually depress the uphill brake pedal until the uphill
wheel stops slipping, thus increasing traction on the
downhill wheel.
To stop mowing,
depress the brake pedal to stop and
disengage the cruise control (if used), move the PTO
switch to DISENGAGE and release (switch returns to
neutral), then fully raise the cutting units.
High Range Ground Speed Operation
- Toro
recommends HIGH RANGE ground speed operation
be performed only on roads with the cutting units in
fully raised position. Start the machine in LOW RANGE,
then shift to HIGH RANGE. The HIGH RANGE Indicator
light will turn ON, indicating the machine is in the HIGH
RANGE mode. To cease HIGH RANGE operation, take
foot off traction pedal and apply the brakes. Move
throttle lever to SLOW and position ground speed
selector in LOW RANGE. If the engine begins to labor
while climbing an incline, ease off on the traction pedal
and shift to
LOW RANGE. This will prevent overload of
the engine and hydraulic system.
CAUTION
Use extreme care while operating in HIGH
RANGE ground speed selection. Watch
closely for bystanders, other vehicles and
possible hidden hazards and be prepared
to stop quickly.
Cruise Control Operation
-While operating the
machine at the desired ground speed, turn the cruise
control switch to ON and press the cruise control
actuating button. The traction pedal will be held in its
position and a constant ground speed will be
maintained. A light on the steering column indicates
the cruise control is in operation. Ground speed can be
changed by over-riding the traction pedal. The pedal
will maintain its new position when the over-riding
force is released.
To stop cruise control operation:
Turn cruise control
switch to OFF position or depress the service brake.
