Abstract: An ingress/egress arrangement for a machine comprises an operator cabin and a walkway system outside the operator cabin. The operator cabin can include a plurality of posts, including first post and a second post, and a door rotatably coupled to the first post so as to be movable between at a fully open position and at a fully closed position. An opening in the operator cabin between the first post and the second post defines a first operator ingress/egress point. The walkway system provides operator access to inside the operator cabin via the door and the opening, and provides operator access to outside the operator cabin. The door, in the fully open position, can restrict operator access toward a front of the machine and can allow operator access simultaneously to the walkway system and a second operator ingress/egress point.
