1. A seed meter disk assembly for a seed meter to dispense individual seeds at desired intervals, the seed meter disk assembly comprising: a rotatable drum having an inner chamber and a planar exterior surface, the inner chamber being in communication with a vacuum source and the exterior surface defining an annular circumferential periphery including a plurality of circumferentially spaced seed apertures connecting the inner chamber and the exterior surface; a plurality of resilient arm members, each of the arm members having a first end secured about a radially inward portion of the exterior surface of the drum, each of the arm members also extending radially outward from the radially inward portion to an outer free end detached from the exterior surface, the outer free end defining an arm member aperture, each of the arm member apertures at least partially overlaid with a corresponding seed aperture; a lifter having a lifting end, the lifting end being engaged with the drum such that the drum is rotatable relative to the lifting end, the lifting end adapted to urge the outer free end of the plurality of arm members away from the exterior surface of the drum as arm members are engaged therewith, the lifter further adapted to allow the outer free end of the arm members to move towards the seed disk as the arm members are disengaged from the lifter.
