TurfDefender Leak Detector
The TurfDefendert is an electronic hydraulic fluid leak
detection device that fits inside the hydraulic tank of your
machine. It is a pressure based system which requires a
sealed hydraulic tank to function properly. Very small
changes to the oil level in the sealed tank result in a large
movement of the leak detector’s internal float. The Turf-
Defender’s internal microprocessor analyzes the float
movement and determines if there is a leak in the sys-
tem.
S Turn ignition key to “ON” position start the system.
The system will reset itself whenever the ignition
key is moved to “OFF” position. Wait 5 seconds,
then move key to “ON” position to restart the sys-
tem.
S When machine is started, the alarm will give one
short beep to indicate that everything is operating
properly. If the alarm makes no noise at all, it should
be checked.
S If the alarm gives 4 short beeps it means a system
problem has been detected and it should be
checked. If the TurfDefendert is programmed w ith
software revisions -- A, B, C, D or E, the alarm will
continue the 4 beep pattern for approximately 1.5
minutes, and then stop. If it is programmed with revi-
sion level F or above, the alarm will repeat the 4
beep pattern twice, and then cease to give further
error indication until another fault is detected. In ei-
ther case, once the ignition key is moved to the
“OFF” position, all alarm reports will cease.
Note: The low or high oil level 4 beep signal may occur
if machine is started on a slope. Move machine to a level
surface, move ignition key to “OFF” position, wait 5
seconds, then move key to “ON” position to r estart the
system.
S If the alarm gives long continuous beeps while
mowing and shuts off the cutting units, it means that
a leak has been detected. On the Reelmaster trac-
tion unit, the red diagnostic lamp on the steering
console w ill also blink indicating the Reelmaster
electronic controller has shut off the cutting unit’s.

Checking
Leak Detector Operation
The operation of the TurfDefendert should be
checked if any of the following conditions occur:
Note: The hand held Diagnostic ACE can be used to
identify many of the problems.
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.
Note: The Diagnostic ACE may have to be connected
before shutting off the ignition key in order to identify the
problem.
WARNING
To identify some problems, engine may have
to be running. To guard against possible per-
sonal injury, engage parking brake and keep
hands, feet, face and other parts of the body
away from moving parts.
