General Run and Transport Problems

Electrical System: Troubleshooting
Problem
The engine continues to run, but should not,
when the key switch is turned to the O
position.
The engine continues to run, but should not,
when the traction pedal is engaged with no
operator in the seat.
The engine shuts off during the operation, but
it is able to start again.
Note: Excessive coolant temperature will
cause the cutting decks to be disengaged
and can cause the engine to shutdown. If the
excessive engine coolant temperature causes
the engine to shutdown, the operator can
start the engine by moving the machine to a
short distance. After starting the engine in this
condition, the engine runs for approximately
10 seconds before it shuts off again.
The engine shuts off when the traction pedal
is pressed.
Note: If the machine controls are not in the
correct position for operating the machine
(e.g., the parking brake is engaged), an
advisory message may be displayed on the
InfoCenter display.
The battery does not charge.
