US Patent 7283903 Enabling system for an implement controller

A system for reliably enabling an implement controller for a work vehicle having a swivel seat with at least two angular positions. The system includes an implement controller for controlling a work implement, seat position detector for determining the positions of the swivel seat, an ignition switch and an implement controller toggle switch. The system is capable of enabling the implement controller under ideal enablement conditions and non-ideal enablement conditions. Ideal enablement conditions exist when the implement controller toggle switch is toggled to an implement controller enabling state while the ignition switch is on and the seat is properly positioned. Non-ideal enablement conditions exit when the implement controller toggle switch is put in an implement controller enabling state in the absence of ideal enablement conditions.
