Vacuum Level, Baffle Position and Vacuum Meter Brush for Corn Seed

For Corn, use the seed corn supplier's information to calculate the seed size in seeds per pound.

EXAMPLE: If the bag label indicates there are 85,000 kernels in the bag and bag weight is 45 lbs., seed size is 1889 seeds per pound (85,000 divided by 45). Referring to the chart, vacuum level should be set at 7 in. when using Standard Corn Disk or 10 in. when using Small Corn Disk for a seed size of 1889 seeds per pound.
