Abstract: A milking stall has a lift rail; an actuator for rotating the lift rail between neutral and maximum positions; a divider mounted on and extending rearward of the lift rail; and, an exit gate mounted on and depending downwardly from the lift rail. The exit gate has a head rail rotatably mounted on the lift rail and a shoulder bar connected to and depending downwardly from the head rail. The exit gate pivots with the lift rail, and the shoulder bar points more rearward in the maximum position than in the neutral position. The head rail is rotatably mounted on the lift rail through a torsion spring. The torsion spring biases rotation of the head rail relative to the lift rail and is pre-loaded on the lift rail to provide a rotational bias to the head rail so that the shoulder bar is urged rearward by the rotational bias.
