  • Publication number: 20070107644
    Abstract: An adjustable singulating brush assembly for a seed meter and method to improve seed singulation of a seed meter. The assembly includes a carrier and a brush selectively adjustably moveable with respect to the carrier. The method to improve seed singulation of a seed meter includes disposing a selectively adjustable moveable brush along a path of travel of the seed selection mechanism of the seed meter between the meter's seed reservoir and said seed discharge opening and selectively moving the adjustably moveable brush with respect to the path of travel of the seed selection mechanism such that the selected seeds meet the preselected brush position to affect removal of extra seeds from the seed selection mechanism so singular seeds are sequentially discharged through said seed discharge opening.

  • Publication number: 20060213407
    Abstract: A system and method to reduce vertical acceleration experienced by a seed meter of a planter row unit during planting operations, the planter row unit having a row unit frame including a hopper support from which the seed meter is operably supported. The system includes a support system operably vertically supporting the hopper support vertically movably independent of the row unit frame.

  • Publication number: 20060011647
    Abstract: An apparatus and method of testing seed singulation of a seed meter. The apparatus includes a frame which supports the seed meter to be tested above a track within which is disposed a continuous flighted belt. A drive system is provided to drive the flighted belt and the seed meter at a preselected speed and seed discharge rate, respectively. In operation, seeds supplied to the seed meter are dispensed by the seed meter in its normal mode of operation onto the moving flighted belt. A sensor disposed along the path of travel of the belt detects the seeds within each passing cell. A computer records and registers data relevant to the singulation accuracy and efficiency of the seed meter.
