A harvester cleaning system (20) may include a first cleaning zone (22) extending in a first inclined plane (32) and a second cleaning zone (24) extending in a second inclined plane (34) different than the first inclined plane (32). The first and second cleaning zones may include first and second sets of louvers (46). A single actuator (30) is operably coupled to the first set of louvers (42) and the second set of louvers (44) to concurrently rotate both the first set of louvers (42) and the second set of louvers (44).
