A power ladder system for an agricultural vehicle includes an agricultural vehicle having a stationary platform and a movable platform with a ladder section connected to the movable platform. An actuator is connected to the movable platform which is configured to move the movable platform between a retracted position and an extended position. An engagement member selectively connects the actuator to the movable platform such that when the engagement member is disengaged the movable platform may be manually operated. The system is configured to automatically extend or retract the movable platform based on various inputs such as pressing a button on a remote or on the ladder, placing the agricultural vehicle in a drive mode, sensing motion of the agricultural vehicle, and opening the door, among other triggers.
