Abstract
A combine including a feeder housing for receiving harvested crop, a separating system for threshing the harvested crop to produce grain and residue, a residue spreader wheel spinning at a speed for expelling the residue from the combine, a residue deflector positioned at an angle for deflecting the expelled residue in a predetermined direction, and a controller. The controller is configured to determine a heading of the combine, determine wind effects on the expelled residue based on an observation of the expelled residue at the determined heading, and adjust at least one of the speed of the residue spreader wheel or the angle of the residue deflector based on the wind effects to achieve a desired residue spread at the determined heading.
