A pitch actuating system for a turbomachine propeller including an actuator having a movable portion configured to be connected to propeller blades for displacement thereof in rotation with respect to the pitch axes of the blades. A first pitch control system for the blades, includes a first transmission screw movable in rotation, a first nut traversed by the first transmission screw and configured to cooperate with the blades for their displacement, an auxiliary system for feathering the blades, which comprise a second fixed transmission screw, a second nut traversed by the second transmission screw and movable in translation on the second nut, and wherein the pitch actuation system is configured so that a translational movement of the second nut causes a translational movement of the first transmission screw.
