Abstract
A blower centered on the axis of a combine immediately to the rear of the seive that carries the majority of the chaff for discharge onto the ground has a bilateral air nozzle that directs high velocity air perpendicular to the axis of the combine to cause the chaff to be spread across a substantial width distance at the rear of the combine. The spreading reduces concentration of such chaff in a narrow path and spreads it fairly evenly on the ground. The spreading reduces or eliminates problems encountered in minimal till or no-till planting that can be caused by having a deep layer of chaff that is toxic to successive crops that are planted without tillage. Any volunteer plants emerging from a chaff row cause competition for the planted crop and reduces yields.
