1. PTO switch
The PTO switch is located on the control panel
out to engage the cutting units and pushed in to disengage the cutting units.
The Standard Control Module (SCM) monitors the position of the PTO switch
(up or down). Using the inputs from the PTO switch and other switches in the
interlock system, the SCM controls the energizing of the reel drive solenoid and
thus, the PTO. If the key switch is in the ON position and the PTO switch is
engaged, the SCM PTO switch input LED should be illuminated.
During the operation of the machine, if the PTO shuts down and
the console temperature warning light is illuminated because of
excessive engine coolant temperature, avoid shutting off the engine.
Under this condition, push the PTO knob down, slowly drive to a
safe flat area, move the throttle lever to the SLOW position, press
the traction pedal, and set the parking brake. Allow the engine to be
idle for several minutes while it cools to a safe level, and check the
cooling system before returning the machine to service.
1. Park the machine on a level surface, lower the cutting deck, set the parking
brake, and shut off the engine.
2. Before you disconnect the PTO switch for testing, ensure that you test the
switch and its circuit wiring as a SCM input; refer to
(SCM) (page 6–45).
3. If the SCM verifies that the PTO switch and circuit wiring are functioning
correctly, no further switch testing is necessary.
