Reduce the ground speed.
Check for mechanical resistance in the
wheels that would make the motors
work extra hard.
Replace and program the traction
motor controller (contact an Authorized
Toro Distributor for assistance). The T5
controller is part of the motor assembly
and is not replaceable separately.
Cycle the key switch.
Use the InfoCenter to calibrate the
traction motor controller.
For SC5, calibrate the traction pedal
first, then the traction motors.
For SC6, calibrate the traction motors.
Clean the air intake screen on the back
of the starter/generator. Be sure the
starter/generator is pulling air through
the air intake by feeling with your hand
or by testing with a piece of paper.
Let the machine cool.
Reduce the cutting loads by reducing
the reel speed or reducing mow speed.
Replace and program the
starter/generator controller (contact
an Authorized Toro Distributor for
assistance).
Inspect the wiring of the speed
sensors.
Check supply voltage to the speed
sensor.
Replace the traction motor.
For SC5 and SC6, use the InfoCenter
to calibrate the traction motors.
For T5, program the traction motor
(contact an Authorized Toro Distributor
for assistance).
Cycle the key switch to clear the fault.
Contact an Authorized Toro Distributor
or the Toro Technical Assistance
Center and report that this fault
occurred.
Cycle the key switch.
If the fault repeats, replace and
program the starter/generator
controller (contact an Authorized Toro
Distributor for assistance).
