engage automated functionality, move the joystick rapidly

maintained after 4 neutral point crossings. Regular bucket
control resumes as soon as the back and forth motion is
stopped.

not move when the control levers are in the hold position.
When released, the control levers will automatically return
to the hold position.

floats across the rough ground.
