An unloading system for a harvester is described as including a crop delivery apparatus, an unloading structure, a belt, and a deflector. The crop delivery apparatus has an outlet through which a flow of crop material is expelled. The unloading structure receives the flow of crop material from the outlet of the crop delivery apparatus and includes a conveyor tube portion extending along a longitudinal axis and defining a passage therethrough with an open intake end. The belt extends into from the intake end through the passage for transporting the flow of crop material through the conveyor tube portion. The deflector extends within the unloading structure from an upstream end to a downstream end such that at least a portion of the flow of crop material received from the crop delivery apparatus contacts the deflector and is directed towards at least a portion of the belt.
