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 means for the blades includes a first transmission screw movable in rotation, a first nut traversed by said first transmission screw and configured to cooperate with the blades for their displacement, second means for feathering the blades, which comprise a second fixed transmission screw, a second nut traversed by said second transmission screw and movable in translation on said second nut, and wherein the system is configured so that a translational movement of the second nut causes a translational movement of the first transmission screw.
