An agitating system includes an agitator disposed within a sub-hopper of the agitating system. The agitator is configured to promote movement of the particulate material through the sub-hopper. The agitating system also includes a deflector assembly configured to movably couple to a bracket at a position laterally offset from a center axis of the agitator. The deflector assembly includes a deflector that establishes a space between the deflector and the agitator, and the deflector is configured to block a portion of the particulate material from exerting a force onto the agitator as the particulate material flows through the sub-hopper.
