The shutter drive apparatus is an apparatus adapted such that the movement of any one shutter louver of a tilt-rod-less shutter results in the corresponding movement of all of the louvers of the shutter. The apparatus is preferably mounted within a tilt-rod-less shutter comprising a shutter frame having at least top and bottom horizontal rails, at least a first side stile and a second side stile, and a plurality of louvers rotatably mounted within the stiles such that a first end of the louvers are freely rotatable within the first side stile, and such that a second end of the louvers are drivably engaged to the apparatus. The apparatus includes a plurality of pinion gears, a face strip, opposing drive strips, and a retainer strip. Each louver is drivably engaged to a different pinion gear and each pinion gear is drivably engaged to the drive strips.
