CONTROL PANEL _________________________________________________________

N. Hydraulic Oil Level Light
Alerts the operator of a low fluid level in hydraulic
tank. This light operates in combination with the
alarm. See Section 4.4.
NOTICE
The warning light will remain on as long as a low oil level
is detected. If the alarm sounds due to low oil level, it can
be disabled by turning switch (O) to OFF.
O. Hydraulic Oil Level / Horn Switch
This switch is used to test the alarm
system or disable the alarm after a low oil
level has been detected. Keep switch in its
ON position when starting and operating
mower. To test alarm, set switch to OFF
and turn ignition key to RUN. See Section
4.4.
P. Mower Lift lever
The mower lift lever raises and lowers the
mowers and operates in either automatic
or manual mode. Push lever forward to
lower mowers, pull back to raise mowers.
Manual Mode - Set mow switch (Q) in its OFF (down)
position. In this position all mowers will raise or lower
while pressure is applied to the lift lever.
Automatic Mode - Set mow switch (Q) in its ON (up)
position. In automatic mode the mowers will lower and
start automatically with a momentary forward movement
of the lift lever. In this mode mowers will only raise to a
"crosscut" position with a
movement of the lift lever.
To raise mowers to their transport position, hold lever
until mowers are fully raised.
NOTICE
While in an Automatic Mode lift or lower cycle, which
lasts approximately 3 seconds, moving the lift lever in the
opposite direction will turn all mowers off, and manual
mode will start for the position selected.
Q. PTO Switch
The PTO switch is a 2-position knob type switch
used to engage and disengage the mowers. It
also sets the mower lift lever (P) in manual or
automatic mode. Set PTO switch in its
disengaged (down) position when starting the
mower.

S. Traction Control
Pressing switch enables controller traction
TC-O/I
control system. This system reduces down
pressure on decks by pulsing the lift circuit,
transferring weight to mower. Reducing down
pressure improves traction, but may cause
decks to float up creating an uneven cut.
To increase down pressure on decks, let go of switch.
This reduces traction, but improves deck contact with
ground.
T. Engine Throttle
Controls engine speed. Run machine at full throttle
during normal machine operation.
U. Cruise Control (Option)
When switched ON the cruise control will
lock the traction pedal in its current position.
Cruise will unlock when switched OFF, or if
parking brake is applied.
V. Ignition Switch
The ignition switch has four positions. OFF-
RUN (ON) - GLOW PLUG - START. In the
RUN position the controller program is
running and input and output circuits are
being monitored. The GLOW PLUG position
has no function for this mower. See Section
5.4 and Parts & Maintenance Manual.
