A screen (48, 50) for an agricultural harvester (10) includes a frame structure (112) having a pair of opposing side members (114) and a first cross member (118) extending between the side members (114) at one end of the side members (114). A plurality of louvers (122) extend between the pair of opposing side members (114). A pair of adjustment slats (126) are respectively associated with and movable substantially parallel to the side members (114), each adjustment slat (126) being further connected to the plurality of shutters (122). The screen (48, 50) is characterized by an adjustment device (130, 160) located below the plurality of shutters (122). The adjustment device (130, 160) includes an actuator (132, 162) and a frame (134, 164). One end (136) of an actuator (132, 162) is connected to the first cross member (118) and the other end (138) of the actuator (132, 162) is connected to the frame (134, 164). The frame (134, 164) has a pair of outboard ends (146), each outboard end (146) being connected to a
