SW Iowa | Seed can only flow through the tubes when enough air can exit the meters at the row units. When the meter hopper is full, air flow is low and does not carry more seed to the meter. When the fan is too high there is still air exiting the system at the meters and allowing more seed to trickle into the seed tubes. Need to balance the air flow from the fan with the airflow needed to fill the meter hoppers and stop when the meters are full. | |
