Checking the Interlock
Switches
Service Interval: Before each use or daily
CAUTION
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
The interlock switches stop the machine when the operator
gets off the seat when the traction pedal is depressed.
However, the operator may get off the seat while the engine
is running and the traction pedal is in the N
Although the engine continues to run if the PTO switch is
disengaged and the traction pedal is released, it is strongly
recommended that the engine be stopped before rising from
the seat.
To check the operation of the interlock switches, perform
the following procedure:
1. Park the machine on a level surface, lower the cutting
unit, stop the engine, and set the parking brake.
2. Press the traction pedal. Turn the key in the ignition
switch to the O
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
rise from the seat, and move the PTO switch to the
O
position.
N
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
position, start the engine, and move

the traction pedal out of the N
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.
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.
position.

EUTRAL
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 Toro
Distributor for assistance in making this adjustment.
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
The blade generally performs best in lower heights of cut–
1.9 to 6.4 cm (3/4 to 2–1/2 inches).
Attributes:
•
Discharge remains more even at lower heights of cut.
•
Discharge has less tendency to throw left and thus a
cleaner look around bunkers and fairways.
•
Lower power requirement at lower heights and dense turf.
High Lift Parallel Sail
The blade generally performs better in the higher heights of
cut– 7 to 10 cm (2 to 4 inches).
Attributes:
•
More lift and higher discharge velocity.
•
Sparse or limp turf is picked up significantly at higher
heights of cut.
•
Wet or sticky clippings are discharged more efficiently
reducing congestion in the deck.
•
Requires more horsepower to run.
•
Tends to discharge further left and can tend to windrow
at lower heights of cut.
WARNING
Do not use the high-lift blade with the mulching
baffle. The blade could break, resulting in personal
injury or death.
