PLANTER whEEL SPEED CALIBRATION
If the planter sensor is not reading correctly, use the following routine to calibrate the sensor.
1. Identify a known good speed source, such as GPS speed, tractor wheel speed, or tractor radar speed.
2. Go to the Speed Settings screen.
3. Begin driving at 5 mph.
4. Record the speed for known good speed source and the planter speed source.
a. Example
i. GPS speed - 5.1 mph
ii. Planter speed - 4.5 mph
5. Divide the planter speed by the known good speed.
a. Example
i. 4.5/5.1 = 0.88
6. Travel to the Seed Meter Drive Settings Screen.
7. Take the value in the field labeled Tire Diameter time the number from step 5.
a. Example
i. 37 x 0.88 = 32.56
8. Enter this new number into the Tire Diameter field.
9. If the planter speed is still off, repeat these steps.
The seed meters diagnostics show the ground speed and seed meter speed for each row. These will vary row to row
when using turning compensation.
