Check the cutting unit and the motor
for mechanical resistance.
Check the bedknife adjustment and
the condition of the reel.
Try spinning the motor without a load.
If it doesn't spin, replace and program
the motor (contact an Authorized Toro
Distributor for assistance).
Cycle the key switch.
Replace and program the motor
(contact an Authorized Toro Distributor
for assistance).
Inspect all cutting unit wiring and
connectors.
Inspect the battery terminals.
Swap cutting reel motors between

the motor if the fault moves to the new
position (contact an Authorized Toro
Distributor for assistance).
Swap cutting reel motors between
cutting units. Replace and program
the motor if the fault moves to the new
position (contact an Authorized Toro
Distributor for assistance).
Inspect the harness connectors at
the cutting unit motor for damage,
corrosion, debris, and proper alignment
of the pins inside the connectors.
Test the connectors for 48V with the
engine shut off and the key in the On
position.
Test the power and ground wiring
resistance in the harness connectors.
Check the 48V logic power connection
to the motor.
If the battery voltage is good with
engine shut off but not good with the
engine on, test the starter/generator.
