Abstract
One embodiment describes a seed metering system that includes a first seed meter that controls seed deposition by a first row unit on a seed planting implement; a first direct vacuum source fluidly coupled to the first seed meter, in which the first direct vacuum source supplies vacuum pressure only to the first seed meter to enable the first seed meter to control seed deposition by the first row unit; a second seed meter that controls seed deposition by a second row unit on the seed planting implement; a second direct vacuum source fluidly coupled to the second seed meter, wherein the second direct vacuum source supplies vacuum pressure only to the second seed meter to enable the second seed meter to control seed deposition by the second row unit; and a control unit communicatively coupled to the first direct vacuum source and the second direct vacuum source, in which the control unit controls vacuum pressure supplied by the first direct vacuum source and the second direct vacuum source independently.
