The double eliminator is set to cover a portion of the hole in the seed disk and is the mechanism to knock multiple seeds away as the disk rotates.ĭouble eliminators are required with flat-type seed disks only and should not be used with cell-type seed disks. By design, a flat seed disk requires higher levels of vacuum than a cell-type disk because there is no pocket or cell to hold the seed. The higher vacuum level will pull more than one seed to the holes in the seed disk.
For difficult to singulate seeds, a flat seed disk and double eliminator is a viable alternative to traditional cell-type seed disks.
