Abstract:
1. A seed distribution system configured to be transported by an agricultural vehicle along a direction of travel comprising: a main frame extending along the direction of travel; a left wing frame extending from a first side of the main frame in a first direction substantially perpendicular to the direction of travel; a right wing frame extending from a second side of the main frame in a second direction substantially perpendicular to the direction of travel; at least one row unit arranged on the first side of the main frame and supported by the left wing frame; at least one row unit arranged on the second side of the main frame and supported by the right wing frame; a first seed reservoir arranged on the first side of the main frame; a second seed reservoir arranged on the second side of the main frame; a plurality of row units arranged on the first side of the main frame and supported by the first wing frame and a plurality of row units arranged on the second side of the main frame and supported by the second wing frame; an air pump connected to a main hose which directs pressurized air stream to a left and right manifold assembly; said left manifold assembly having a plurality of manifold outlets corresponding to said number of row units mounted to said left wing frame; said right manifold assembly having a plurality of manifold outlets corresponding to said number of row units mounted to right wing frame; said plurality of manifold outlets connected to a left and a right seed delivery hose assembly system each having a plurality of seed delivery hoses coupled as bundles to each respective manifold outlets; said left seed delivery hose assembly system connecting the first seed reservoir to the at least one row units arranged on said second side of the main frame; said right seed delivery hose assembly system connecting to the second seed reservoir to the at least one row unit arranged on the first side of the main frame; said left seed delivery hose assembly extends transversely from the left manifold outlets across said main frame and direct air and seed to respective row units mounted on said right wing frame; and said right seed delivery hose assembly extends transversely from the right manifold outlets across said main frame and direct air and seed to said row units mounted on the left wing frame.
