Beschreibung
Zusammenfassung:	The invention provides a system for equalizing airflow in lines delivering product-conveying air to boom sections of an agricultural machine by controlling valves, such as electronically, in each air distribution line to induce additional pressure drops in lines which would cause imbalance in the system. Such valves can include, but are not limited to: ball valves, butterfly valves, gate valves, globe valves, diaphragm valves, pinch valves and/or plug valves. With the proposed system, the lines of least pressure drop can be induced with additional pressure drop by particular valves in order to bring the lines back to a balanced state.
