A control system is disclosed for controlling a power takeoff (PTO) shaft of a work vehicle (e.g., a tractor). The work vehicle includes an engine and an operator station, and the PTO shaft transfers power from the engine to an implement. The control system includes a remote switch, a vehicle speed sensor, and a control circuit. The remote switch is located remotely from the operator station and provides a remote switch signal to the control circuit to engage and disengage rotational movement of the PTO shaft. The vehicle speed sensor provides a vehicle speed signal to the control circuit representative of a speed of the work vehicle. The control circuit receives the remote switch signal and the vehicle speed signal and, when the vehicle speed signal exceeds a predetermined vehicle speed, the control circuit prevents engagement and disengagement of the PTO shaft with the remote switch.
A control system for controlling a power takeoff shaft of a work vehicle, the work vehicle configured for travel across a work surface and having an operator station, the control system comprising:
A control system for controlling a power takeoff shaft of a work vehicle, comprising:
A method for controlling a power takeoff shaft of a work vehicle, the work vehicle configured for travel across a work surface, the method comprising:
The method of clam 15, further comprising selecting one of the local switch signal and the remote switch signal to control the power takeoff shaft.
