One embodiment describes a seed gate assembly disposed between a seed storage tank and a seed meter. The seed gate assembly includes a gate barrier that controls seed flow from the seed storage tank into the seed meter by moving to an open position that enables seed flow from the storage tank into the seed meter and by moving to a closed position that blocks seed flow from the storage tank into the seed meter; and a first seed agitator extending substantially perpendicularly from a surface of the gate barrier, in which the first seed agitator extends into the seed storage tank as the gate barrier moves toward the closed position to dislodge clumped seeds in the seed storage tank.
