Choosing Seed Disks

IMPORTANT: If hopper box treatments are used, be sure to follow the chemical manufacturer's recommendations carefully. Dry powder or fast drying liquid treatments are generally recommended. HIGH OIL CONTENT TREATMENTS ARE NOT RECOMMENDED.

Chemical reaction between farmer-applied seed treatments and treatments commercially applied to seed can cause the seed treatments to become sticky. Certain temperature and humidity levels can further complicate material compatibility. Treatments that adhere to the vacuum meter components can cause reduced population and spacing control.

Check with your chemical and seed supplier for treatment compatibility.

The vacuum seed meter will accurately plant most sizes of corn, acid-delinted cotton, sorghum, soybeans, edible beans, sugar beets, sunflowers, and popcorn.

Use the following guidelines to select the seed disk and the seed size that will optimize vacuum meter performance.

CORN

A - STANDARD CORN SEED DISK - Part No. A50617

B - SMALL CORN SEED DISK - Part No. A43215

C - SUNFLOWER/POPCORN DISK - Part No. H136478

Corn seed size and shape varies widely. The vacuum seed meter corn disks can individually handle a large portion of the full size range.

The chart illustrates the range of seed sizes best suited for use with the respective seed disks.

The chart represents the seed size range where optimum performance can be expected with each seed disk. Select the disk which best handles the seed to be planted or best represents the majority of seed sizes to be planted.

If several seed sizes are to be planted and their seed size falls within the overlapping areas of the two seed disks, it is recommended that BOTH seed disks be ordered to optimize performance to the individual seed shape.
