Abstract
An embodiment includes a combine having a feeder housing for receiving harvested crop, a separating system for threshing the harvested crop to separate grain from residue, a residue spreader wheel spinning for expelling the residue from the combine, and a controller that controls the combine. The controller is configured to control the residue spreader wheel to continuously oscillate between a first speed less than a nominal speed and a second speed greater than the nominal speed while spreading the residue.
