Abstract: A system includes a selector switch and a control device. The selector switch is positioned inside a cab of a work vehicle and coupled to main and remote switches, which are in turn coupled to a voltage source. The selector switch can be used to select standard and remote modes that allow, respectively, the main and remote switches to engage and disengage a power takeoff (PTO) on the work vehicle. The control device is coupled to the switches and the PTO to interpret combinations of positions of the switches for engagement and disengagement of the PTO, preferably based on testing of the combinations with stored preselected conditions. Further, the control device activates warning signalers according to conditions of the system.
