Checking the
Safety-Interlock Switches
Service Interval:
Before each use or daily
CAUTION
If the safety-interlock switches are
disconnected or damaged, the machine could
operate unexpectedly and cause personal
injury.
•
Do not tamper with the safety-interlock
switches.
•
Check the operation of the safety-interlock
switches daily and replace any damaged
switches before operating the machine.
The machine has interlock switches in the electrical
system. These switches disengage either the traction
or the PTO whenever you leave the seat. Although
the engine continues to run if you disengage the PTO
switch, and you release the traction pedal, shut off the
engine before rising from the seat.
1.
Park the machine on a level surface, lower the
cutting unit, shut off the engine, and engage the
parking brake.
2.
Press the traction pedal. Turn the key in the
ignition switch to the O
N
position.
Note:
If the engine cranks, there is a
malfunction in the interlock system. Correct this
malfunction before operating the machine.
3.
Turn the key in the ignition switch to the O
N
position, start the engine, rise from the seat, and
move the PTO switch to the O
N
position.
Note:
The PTO should not engage. If the
PTO engages, there is a malfunction in the
interlock system. Correct this malfunction before
operating the machine.
4.
Engage the parking brake, turn the key in the
ignition switch to the O
N
position, start the
engine, and move the traction pedal out of the
N
EUTRAL
position.
Note:
The InfoCenter displays "traction denied"
and the machine should not move. If the
machine does move, there is a malfunction in
the interlock system. Correct this malfunction
before operating the machine.
5.
Start the engine with the PTO engaged.
Note:
If the engine cranks, there is a
malfunction in the interlock system. Correct this
malfunction before operating the machine.
Checking the Blade
Stopping Time
Service Interval:
Before each use or daily
The blades of the cutting deck should come to a
complete stop in approximately 5 seconds after you
shut down the cutting-deck-engagement switch.
Note:
Make sure that the decks are lowered onto a
clean section of turf or hard surface to avoid thrown
dust and debris.
1.
Have a second person stand back from the deck
at least 6 m (20 feet) and watch the blades on
1 of the cutting decks.
2.
Shut the cutting decks down and record the time
it takes for the blades to come to a complete
stop.
Note:
If this time is greater than 7 seconds,
the braking valve needs adjustment. Call your
authorized Toro distributor for assistance in
making this adjustment.
Burnishing the Brakes
To ensure optimum performance of the parking-brake
system, burnish (break in) the brakes before use.
Set the forward traction speed to 6.4 km/h (4 mph)
to match the reverse traction speed (all 8 spacers
moved to the top of the mow-speed control). With
the engine at high idle, proceed forward with the
mow-speed-control stop engaged and ride the brake
for 15 seconds. Proceed backward at full reverse
speed and ride the brake for 15 seconds. Repeat this
5 times, waiting 1 minute between each forward and
reverse cycle to avoid overheating the brakes; refer to
Adjusting the Parking Brakes (page 64)
.
Selecting a Blade
Standard Combination Sail
This blade was designed to provide excellent lift and
dispersion in almost any condition. If more or less lift
and discharge velocity is required, consider a different
blade.
Attributes: Excellent lift and dispersion in most
conditions
Angled Sail (Not CE Compliant)
The blade generally performs best in lower heights of
cut—1.9 to 6.4 cm (3/4 to 2-1/2 inches).
