A headlands control system for a winged agricultural implement includes a headlands actuator operatively connected between implement wing actuators for establishing operation in either of two modes. In the first mode, when the headland actuator is in a first position (e.g. extended), the wing actuators are provided extra downward range to pivot and bias the wing sections downward below horizontal as may occur during operation over uneven ground. In the second mode, when the headland actuator is in a second position (e.g. retracted) and the implement is raised (e.g. at the headlands), the downward range of the implement wings is more limited (as compared with the first mode) at the point where the wing actuators are fully extended. This system thus provides an apparatus for preventing implement wings from drooping in the headland position so the operator is not required to reset the wing control from float mode, or from down pressure mode, depending on what is equipped.
