Abstract: An access ladder assembly for an agricultural machine having a body with an elevated operator's station. The ladder assembly includes a ladder that is mounted to the frame of the machine by a pivot mechanism that allows the ladder to be moved in either rotational direction about both a generally horizontal axis and a generally vertical axis. A locking mechanism releasably holds the ladder in an angularly adjusted position about both of these axes. A release mechanism conveniently located relative to the operator's station controls operation of the locking mechanism. The ladder assembly further includes rail structure carried by the ladder and movable about a generally vertical axis to either of two adjusted positions.
