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 2.4.
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 2.4.
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 momentary backward
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.
R.Light Switch

S. Traction Control
Pressing switch enables controller traction control
TC-O/I
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. 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.
