A control system for an implement hitch of an agricultural vehicle, wherein the hitch is mounted to the vehicle and includes one or more hydraulic cylinders or other actuators operable to raise and lower the hitch between minimum and maximum heights relative to the vehicle and hold the hitch static at one or more heights between the minimum and maximum heights. The control system includes a rocker control device having a first operating position and being 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) is connected to the rocker control device and controls operation of the or each of the hydraulic cylinders or actuators and thereby control raising and lowering of the hitch in response to user operation of the rocker control device. The ECU is operable to control raising and lowering of the hitch to move it to a selected one of two or more previously stored positions between the said minimum and maximum heights, and to switch between the said previously stored positions in response to a predetermined first actuation operation of the same rocker control device. Preferably, the same rocker control device is used to control the input and storage of at least one further height value.
