A rotor blade folding system includes a blade lock assembly, a rotary actuator and a blade fold controller to selectively position each rotor blade assembly in a particular predetermined folded position. The blade lock assembly positions each blade yoke in a predetermined lead/lag and pitch position to minimize strain upon an elastomeric bearing between the blade yoke and the rotor hub. The rotor blade is then folded relative to the blade yoke to a predetermined blade fold angle.
