Abstract: The volume and composition of the material in the tailings returns is directly responsive to the major combine settings, and dependent on the throughput and crop conditions. The research has shown that tailings returns frequently contain loose grain that does not need to be rethreshed. Loose grain in the tailings is more susceptible to damage when it is returned to an aggressive threshing cylinder or rethresher. Published data other authors is showed some evidence that grain damage could be reduced with the use of an auxiliary tailings rethresher instead of returning the tailings to the main threshing cylinder. The amount and composition of the tailings are strong indicators on how a combine is performing. Low throughput and its consequential grain damage can cause dramatic increases in combine losses. High levels of damaged grain in the tailings indicate excessive speed of rethreshing or inadequate throughput. Power consumption was found to be dependent on rethresher throughput. When the feederate is changes from 0.2 kg-s"1 to 1.0 kg-s"1, the power consumption for rethreshing of wheat increases from 1.53 kW to 2.44 kW
