Abstract
A seed metering mechanism including a seed singulator assembly for reducing the likelihood of or eliminating double or excess seeds being carried by a seed disc of the seed metering mechanism to a discharge area of the seed metering mechanism for deposit to the ground. The singulator assembly is disposed downstream of a seed chamber and upstream of the seed discharge area of a seed metering mechanism. The seed singulator of the present invention includes a seed engaging member arranged on opposite sides of the path of travel of a circular array of openings on a seed disc of the seed metering mechanism. The spacings between the seed engaging members being such that only a single seed carried in each opening is permitted to pass therebetween.
