Store the Diagnostic ACE in a dry, secure
location in the shop, not on the machine.
HYDRAULIC VALVE SOLENOID
FUNCTIONS
Use the list below to identify and describe the differ-
ent functions of the solenoids in the hydraulic mani-
fold. Each solenoid must be energized for the func-
tion to occur.
Solenoid Function
VS1,S1 Front reel circuit
VS2,S2 Rear reel circuit
S3 Lift / lower front wing cutting units
S4 Lift / lower center cutting unit
S5 Lift / lower rear cutting unit
S6 Lower any cutting units
S7 Lift any cutting units
S8,S9 Backlap any cutting units
HEIGHT-OF-CUT SELECTION
POTENTIOMETER REPLACE-
MENT
The height-of-cut selection potentiometer is factory
calibrated. If the height-of-cut selection potentiome-
ter should be replaced for any reason, the new poten-
tiometer must be calibrated to assure correct clip . If
the potentiometer is not calibrated correctly, the clip
may be as much as 2 or 3 settings different from the
desired setting. This calibration must be done by
your Toro distributor.

OPERATING

CHARACTERISTICS
Familiarization—Before mowing grass, practice
operating the machine in an open area. Start and
stop the engine. Operate in forward and reverse.
Lower and raise the cutting units and engage and dis-
engage the reels. When you feel familiar with the
machine, practice operating up and down slopes at
different speeds.
The brakes can be used to assist in turning the
machine. However, use them carefully, especially on
soft or wet grass conditions because the turf may be
torn accidentally. Individual turning brakes may also
be used to help maintain traction. For example, in
some slope conditions, the uphill wheel slips and
loses traction. If this situation occurs, depress the
uphill turn pedal gradually and intermittently until
the uphill wheel stops slipping, thus, increasing trac-
tion on the downhill wheel.
Warning: When operating the machine, always
use the seat belt and roll-over protection system.
Warning System—If a warning light comes on dur-
ing operation, stop the machine immediately and cor-
rect the problem before continuing operation.
Serious damage could occur if the machine is operat-
ed with a malfunction.
Mowing—Start the engine and move the throttle to
FAST so the engine is running at maximum speed.
Move the ENABLE / DISABLE switch to ENABLE
and use the LOWER MOW / RAISE lever to control
the cutting units (front cutting units are timed to
lower before the rear cutting units). To move forward
and cut grass, press the traction pedal forward.
Maintain a speed which does not result in the Reel
Control LIght illuminating. Gradually increase or
decrease traction speed to ensure proper clip.
Transport—Move the ENABLE / DISABLE switch
to DISABLE and raise the cutting units to the trans-
port position. Be careful when driving between
objects so you do not accidentally damage the
machine or cutting units. Use extra care when oper-
ating the machine on slopes. Drive slowly and avoid
sharp turns on slopes to prevent roll overs. The cut-
ting units should be lowered when going downhill
for steering control.
Selecting Clip Rate (Reel Speed)—The automatic
clip control programmed into the machine controller
requires that it be told at what height of cut the
machine is being operated and whether the machine
is equipped with 5- or 8-blade reels. Refer to
Selecting Clip Rate (Reel Speed).
When the machine is being operated in such a way
that it can control the reel speed to achieve the
desired clip, the reel control light will not light. If
the reel control light is illuminated, the traction
speed is too low or too high to allow the machine to
achieve the desired clip.
