Diagnostics System

Diagnosing the Service
Indicator Light
The service indicator light illuminates in the event of a
fault in the machine. When this light is on, you can access
the computer codes to diagnose the problem by entering
diagnostic mode. In diagnostic mode, the service indicator
light will flash a number of times giving you the error code
that you or your distributor can use to identify the problem.
Note: The engine cannot be started in diagnostic mode.
Entering Diagnostic Mode
1. Stop the machine, set the parking brake, and turn the
ignition key to the O
2. Move the functional-control lever to the T
position.
3. Ensure that the backlap lever is set to the F
(F) position.
4. Get off of the seat.
5. Hold the raise/lower mow control in the R
position.
6. Turn the ignition switch to the R
7. Count the codes as they begin to flash (you may release
the raise/lower mow control once they begin flashing).
When finished, turn the key to the O
diagnostic mode.
Determining the Error Code
The system will display the last 3 faults that occurred in the
last 40 hours. It displays the faults through a series of blinking
lights, as follows:
•
If there are no faults, the light with blink steadily at a
medium rate without pauses (1 Hz).
•
If there is a fault, it will first blink the tens place, followed
by a pause, followed by the ones place. For the following
examples, a # represents a blink. Examples:
– If the code is 15, the blink pattern will be #_#####
– If the code is 42, the blink pattern will be ####_##
– If the code is 123, the blink pattern will be
############_###
•
If there are more than one fault, the tens place of the next
fault will begin after a pause after the ones place of the
first fault.
Note: The system stores only the three most recent fault
codes.
For a list of error codes, refer to your Authorized Distributor
or the Service Manual.

Storage

If you wish to store the machine for a long period of time, the
following steps should be performed prior to storage:
1. Remove accumulations of dirt and old grass clippings.
Sharpen the reels and bedknives, if necessary; refer to
the Cutting Unit Operator's Manual. Use a rust preventive
on bedknives and reel blades. Grease and oil all
lubrication points.
2. Block up the wheels to remove any weight on the tires.
3. Drain and replace the hydraulic fluid and filter and
inspect the hydraulic lines and fittings. Replace, if
necessary; refer to
Filter (page 43)
Hoses (page 43).
4. All fuel should be removed from the fuel tank. Run
the engine until it stops from lack of fuel. Replace the
fuel filter; refer to
Separator (page
5. While the engine is still warm, drain the oil from the
crankcase. Refill it with fresh oil; refer to
