Abstract
An agricultural harvesting machine includes a tailings conveyor housing. The agricultural harvesting machine provides a cleaning device for cleaning threshed and separated grain. The tailings conveyor housing collects tailings from the cleaning device and propels the tailings with a first impeller against a first rethreshing member and radially to a second impeller. The second impeller propels the tailings against a second rethreshing member and radially to a third impeller. The third impeller propels the tailings against a third rethreshing member and radially through the second opening and past a baffle, where the tailings are redirected back to the cleaning device and spread out over the cleaning device.
