摘要：
A grain cleaning system (26) in an agricultural harvester (10), that includes a chaff pan (70) with a pivotal axis (A1) near an end of the chaff pan (70). The chaff pan (70) has a dual locking system (100, 200) coupled thereto for holding of the chaff pan (70) in two different positions. The dual locking system (100, 200) has a first over-center locking arrangement (102, 202) and a second over-center locking arrangement (104, 204). The first locking arrangement (102, 202) is used to hold the chaff pan (70) in an upward position when the first locking arrangement (102, 202) is locked. The first locking arrangement (102, 202) includes a first linkage element (110, 210); and a second linkage element (108, 208). The second locking arrangement (104, 204) holds the chaff pan (70) in a locked downward position when the second locking arrangement (104, 204) is locked. The second locking arrangement (104, 204) includes a first linkage element (110, 210); and a second linkage element (112, 74). The first linkage elemen
