<p>A spreader system (12) for an agricultural harvester (10), including a first spreader disc (42) and a second spreader disc (88). The first (42) spreader disc and second spreader disc (88) have at least one paddle (46, 90) and are configured to receive a first agricultural material, a second agricultural material, or a combination thereof, and to distribute the first agricultural material, the second agricultural material, or the combination thereof, throughout a field. The spreader system (12) is characterized by a hood assembly (30) including a rotatable first hood (48, 84, 120) and a rotatable second hood (49, 85, 122). The first hood (48, 84, 120) and second hood (49, 85, 122) cover a portion of a respective first disc (42) and second disc (88) and are configured to rotate between a first position and a second position. In the first position the first hood (48, 84, 120) and second hood (49, 85, 122) block upward and rearward flow of a first agricultural material, a second agricultural material, an airflow, or a combination thereof. In the second position the first hood (48, 84, 120) and second hood (49, 85, 122) are configured to facilitate upward and rearward flow of the first agricultural material, the second agricultural material, the airflow, or the combination thereof.</p> |
