1. PTO switch
The PTO switch is located on right side of the steering column.
Pull it out the PTO switch to engage the PTO electric clutch.
The electronic control unit (ECU) 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 ECU controls the energizing of the electric PTO clutch.
During the operation of the machine, if the PTO shuts down due to
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, release
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.
