1. A dry product spreader comprising;
a bin comprising a bin discharge opening, wherein the bin is capable of containing a dry product material;
a conveyor located at a bottom of the bin, wherein the conveyor is capable of discharging the dry product material from the bin through the bin discharge opening where the discharging of the dry product material from the bin through the bin discharge opening forms a dry product material stream, wherein the dry product material in the dry product material stream flows in a first direction;
one or more spinners for spreading the dry product material and positioned to receive the dry product material from the bin discharge opening;
a material conveyor to displace a portion of the dry product material received through the bin discharge opening before the dry product material reaches the one or more spinners such that the portion of the dry product material is displaced from the dry product material stream in a second direction different from the first direction; and
a distribution manifold configured to receive the portion of the dry product material displaced by the material conveyor;
wherein the distribution manifold is configured to return the portion of the dry product material displaced by the material conveyor to be spread by the one or more spinners such that the portion of the dry product material is returned to the dry product material stream.
