Gear Ratio Drawing - For John Deere Pro-Shaft™ Drives
Seed Rate Drive Setting (Calculating a Gear Ration for John Deere Pro-Shaft Drives)
Carry the Decimal place to the nearest 0.001 for accurate results.
Seed Ratio Calculation Example Procedure - for Pro-Shaft™ Drives
The example outlined below assumes that you have a single planter drive motor. Step 5 notes that this
process has multiple steps if you have more than one Stepper Seed Motor Drives.
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. On the Pro-
Shaft Drive, the number of teeth on the driven sprocket is always 28, and the number of teeth on the drive
sprocket is always 19.
4. Take the ratio of the Seed Rate Motor and multiply it by the ratio of the other sprocket combinations.
5. Repeat this process if you have multiple hydraulic drives. Enter the gear ratio for each motor under the
appropriate tab on the display.
Note: If you have additional motor drives on the planter and these motor drives have the same total gear ratio,
enter that number into the other channels.
