Flat type seed meter disk with axially offset surface

摘要

A flat disk type circular seed disk is provided with a series of circumferentially arranged seed attracting apertures. The apertures are spaced along a circumferential rim offset axially from the remainder of the disk to approximate the seed release location and characteristics of a cell type seed disk. The offset allows the seed to fall in the correct location of the seed tube to reduce or eliminate unwanted seed bounce and provide better seed delivery to the ground and better seed spacing as compared to flat disks without the offset. In one embodiment, the rim has a surface angled with respect to the rotational plane of the seed disk to impart an axial component to the seed trajectory. A tortuous wall between the rim and the remainder of the disk provides seed agitation.
