A control system is disclosed for use in a zero turn vehicle, including an electric controller in communication with a pair of independent drive units. A joystick provides user inputs to the controller to control the rotational speed and direction of the drive units. The joystick includes a vertical stalk pivotable between a plurality of pivot positions, where each of the plurality of pivot positions corresponds to a particular rotational speed and direction of each of the driven wheels. A selector switch may be used to select one of a plurality of driving modes stored in the electric controller, wherein each of the plurality of driving modes maps a different set of speeds and directions for each of the driven wheels onto the plurality of pivot positions. The joystick may also rotate about a vertical axis to provide zero turn capability.
