3.20 Operator Seat
Check that the operator seat pan is properly latched and operator seat is secure. Be sure
the seatbelt is secure and operable.
Adjust the seat forward or back so that the operator can easily reach the control panel,
steering control arms, and mower deck height adjustment pedal.
3.21 Steering Control Arms
Check that both steering control arms are properly linked, free of debris, and operating
freely. Swing the arms toward the operator seat, removing them from the neutral lock
position. Slowly push both arms all the way forward, then all the way back. They should
both move smoothly and easily, with no sticking, obstruction, or uneven tension. They
should also “snap” back to neutral position, which is straight up and down and centered
with the neutral position lock (notch in the frame).
Be sure to return and lock both control arms into neutral position.
The control arms can be adjusted for operator comfort by repositioning the control arms
on the control assembly.
3.22 Lights
Check the function of the headlights and hazard lights. From the operator seat, turn the
key switch clockwise to the RUN position. DO NOT START THE ENGINE. Using the tog-
gle switches located on the lower right of the control panel, turn on first the headlights,
then the hazard lights, checking them for proper operation. If any lights fail to activate,
repair the problem before attempting to operate the Articulator.
Turn the headlights and flashers off, and return the key switch to the OFF position.
NOTE: Any time the ignition switch is activated for 9 seconds or more, an audible warning
beeper will sound until either the ignition switch is turned off, or the engine is started.
