摘要： Systems and methods utilizing automation logic for powered ladders of work vehicles, including harvesters. A portion of the powered ladder can be displaced relative to other portions of the ladder so that the powered ladder is in either a folded or unfolded orientation. A controller can determine whether a secondary device, such as, for example, a header, is attached to the work vehicle. In response to at least determining the secondary device is not attached to the work vehicle, the folded powered ladder can be automatically displaced from an extended position to a retraced position. Upon detection of either or both a change in position of an operator, and a predetermined operational status of the work vehicle, the ladder can be displaced away from the retracted position, and the second portion of the powered ladder can be displaced so that the powered ladder can return to the unfolded orientation.
