three hydraulic motor drives via the display. Configure the Stepper Seed Rate Control module in the
following order.
1. Configure Stepper Seed Rate Control module

2. Enter Controller Settings
Included the Max Meter Speed, Gear Ratio and Minimum Allowable Ground Speed.
See
“Controller Settings for Stepper Seed Rate Motor Drives” on page 168.
3. Prime the Stepper Seed Meter
This fills the seed meter with seed to avoid skips.
See
“Priming Seed Rate Meters” on page 173
.
4. Meter Calibration

the number of seeds dropped per one revolution of the seed meter. See “Calibrating Seed Rate
Meters” on page 174.
- b. Perform a Seed Meter Calibration. A new calibration should be performed if the as-applied seed rate
does not match the actual population planted. See “Calibrating Seed Rate Meters” on page 174.
