Abstract
A seed meter is provided having an endless belt as a seed transport member together with a pressure differential to hold the seed onto the belt. The use of an endless belt as the seed transport member enables the spatial orientation of the seed transport member to vary from location to location along the path of the belt where different seed meter functions are performed. The belt allows greater freedom in determining the location of the seed pick-up region and the seed release or removal region beyond the constraints of a fixed diameter seed disk. The belt further allows for a narrow envelope seed meter which can cross-feed seed into a substantially vertically oriented delivery device.
