Abstract
A product-on-demand delivery system for an agricultural machine having a main hopper arrangement wherein each outlet nozzle of the main hopper nozzle manifold is connected to plural product hoses that are each in communication with an auxiliary product hopper of an application unit. The nozzle manifold includes an inlet for receiving pressurized air, and an outlet nozzle allowing air with entrained seed or product to exit the main hopper. The outlet nozzle includes a splitter portion, such as a Y-shaped fitting, having a single splitter inlet and two splitter outlets. The single splitter inlet is coupled to a nozzle portion of the outlet nozzle and the two splitter outlets are coupled to two product hoses that are each coupled to a respective application unit. An internal divider wall extends through the nozzle portion and partially through the splitter portion from the splitter inlet to the splitter outlets. The divider wall evenly divides flow of air and entrained seed or product between the two splitter outlets to the two application units.
