1. A system for controlling an operation of agricultural implements, the system comprising:
a work vehicle including a hitch assembly including a hitch frame and a draw point moveable relative to the hitch frame, the work vehicle further including an actuator configured to move the draw point relative to the hitch frame, the work vehicle further including a vehicle-based sensor and a vehicle-based controller communicatively coupled to the vehicle-based sensor; and
an implement configured to be towed by the work vehicle, the implement configured to be coupled to the draw point such that movement of the draw point relative to the hitch frame adjusts the position of the implement relative to the work vehicle, the implement including an implement-based sensor configured to detect an operational parameter indicative of the operation of the implement, the implement further including an implement-based controller communicatively coupled to the implement-based sensor, the implement-based controller configured to receive the sensor data from the implement-based sensor and transmit signals to the vehicle-based controller requesting the vehicle-based controller to control an operation of the actuator based on sensor data received from the implement-based sensor to adjust the operational parameter of the implement,
wherein the vehicle-based controller is configured to determine when the implement is present within a headlands based on the sensor data received from the vehicle-based sensor and ignore the signals received from the implement-based controller requesting that the vehicle-based controller adjust the operation of the actuator when it is determined that the implement is present within the headlands; and
wherein the vehicle-based controller is further configured to operate the actuator such that the draw point is moved relative to the hitch frame so as to reduce a turning radius of the work vehicle and implement when it is determined that the implement is present within the headlands and the vehicle-based controller is ignoring the signals received from the implement-based controller.
