Seed Ratio Calculation Example Procedure for Shaft Drives
This example assumes a single drive motor. Step 5 notes that this process has multiple steps for more
than one hydraulic drive.
1. Beginning with the Seed Rate Motor, count the number of teeth on the drive sprocket. Then count the
number of teeth on the driven sprocket.
2. Divide the number of teeth on the driven sprocket by the number of teeth on the drive sprocket. This
is the ratio of the Seed Rate motor.
3. Repeat the process for each sprocket combination in the drive system back to the meter.
4. Take the ratio of the Seed Rate Motor and multiply it by the ratio of the other sprocket combinations.
5. Repeat this process for multiple hydraulic drives. Enter gear ratio for each motor under the appropriate
tab.
Note: Enter the number into the other channels for additional motor drives if they have the same total gear
ratio.

The Seed Meter Prime is used to charge the seed meter when filling with seed.
Press: Map button > Meter RPM button > Planter Drives > Prime Seed Meter button
A message displays, stating “Seed Meter Prime in Progress.” While this message displays, the seed
meter will turn one (and only one) revolution automatically. When complete, return to the Seed Rate
Planter Control screen.

The Meter Calibration number allows the seed meter to communicate the correct seed population to the
display. Assuming the Controller Settings are correct for the seed rate, this Meter Calibration number,
which is based on the number of cells on the seed meter, should not need to be adjusted. However, you
may wish to recalibrate after changing seed types and treatments.
Notes:
• The seed rate meter calibration does not recalibrate any previously-logged planting data.
• This recalibration number applies to a specific crop type, i.e., corn. Normally, there is no need to
recalibrate when switching varieties within the same crop type.
