1. A control system for an implement hitch of an agricultural vehicle, wherein the hitch is mounted to the vehicle and includes at least one actuator operable to raise and lower the hitch between minimum and maximum heights relative to the vehicle and hold the hitch static at, at least one height between the minimum and maximum heights, the control system comprising:
a rocker control device having a first operating position and movable in a first direction to a first limit position and in a second direction to a second limit position;
an electronic control unit (ECU) connected to the rocker control device and configured to control operation of each of the actuators and thereby control raising and lowering of the hitch in response to operation of the rocker control device;
wherein the ECU is operable to control raising and lowering of the hitch according to one of at least two control modes, and to switch from a first mode of the control modes to a second mode of the control modes in response to a predetermined first actuation operation of the rocker control device.
