Abstract: A harvesting head (100) has a laterally extending frame (102) on which left and right side conveyor belts (120, 122) are supported. A center conveyor belt (124) is disposed between the left and right side conveyor belts (120, 122) to receive crop material from the left and right side conveyor belt (120, 122) and carry it rearward. Crop deflectors (112, 114) are disposed between the left side conveyor belt (120) and the center conveyor belt (124) and between the right side conveyor belt (122) and the center conveyor belt (124) to deflect cut crop material away from the gaps between the belts and prevent substantially all the cut crop material from being drawn into the gaps between the belts and ejected onto the ground.
