TurfDefender
TM
Leak Detector (Optional)
The optional TurfDefender
TM
is an electronic hydraulic
fluid leak detection device that fits inside the hydraulic
reservoir of your machine (Fig. 12). It is a pressure
based system which requires a sealed hydraulic reser-
voir to function properly. Very small changes to the oil
level in the sealed reservoir result in movement of the
leak detector’s internal float. The internal microproces-
sor of the TurfDefender
TM
analyzes the float movement
and determines if there is a leak in the hydraulic system.
D Turn ignition switch to “ON” position to start the sys-
tem. The system will reset itself whenever the igni-
tion switch is moved to “OFF”. Wait 5 seconds, then
move switch to “ON” position to restart the system.
D When the machine is started, the alarm should give
one short beep to indicate that everything is operat-
ing properly. If the alarm makes no noise at all, see
Checking TurfDefender
TM
Operation in this section.
D If the alarm gives 4 short beeps, a system problem
has been detected and it should be checked by a
technician.
NOTE: The 4 short beep signal may occur if the ma-
chine is s tarted on a slope. Move machine to a level
surface, move ignition switch to “OFF” position, wait
5 seconds, then move switch to “ON” position to re-
start the system. Repeat this cycle twice.
D If the alarm gives a loud continuous beep while mow-
ing and the c utting units are shut off, a hydraulic leak
has been detected. On the traction unit, the diagnos-
tic light on the control panel will also blink indicating
the ECM has shut off the cutting units.
Checking TurfDefender
TM
Operation
When any of the following conditions occur, the opera-
tion of the TurfDefender
TM
should be checked:
A. No beeps are heard when ignition switch is
turned “ON”.
B. Any time the machine gives a series of 4 short
beeps.
C. False alarms are observed.
1. Park machine on a level surface, lower cutting units,
stop engine and engage parking brake.
2. Raise hydraulic reservoir cover. Locate leak detector
wire harness loopback connector identified with a green
hydraulic symbol tag (Fig. 12). Carefully unplug loop-
back connector from harness connector.
3. Connect the Diagnostic Display connector to the cor-
rect harness loopback connector. Install TurfDefender-
TM
overlay decal (supplied with TurfDefender
TM
kit) onto
the Diagnostic Display (Fig. 13).
4. Turn the ignition switch to the RUN position, but do
not start machine.
NOTE: Red text on the overlay decal refers to inputs
and green text refers to outputs.
5. The red “Inputs Displayed
” LED (Light Emitting
Diode), on lower right column of the Diagnostic Display,
should be illuminated (Fig. 14). If green “Outputs
Dis-
played
” LED is illuminated, press and release the toggle
button, on the Diagnostic Display, to change LED to “
In-
puts Displayed
”. Do not hold toggle button down.
