Troubleshooting
When starting with a new planter, a new crop, or a new population, it is important to physically check what the
seed monitoring system console is reporting by digging and observing seeds. This is to verify that the planter
is set up correctly to plant the desired population. Do not rely solely on the population reported by the console.
Plant a short distance and dig the seeds, or run with the closing wheels wired up to leave an open seed
trench. Based on seeds found, determine an average distance between seeds. Compare the distance
between seeds to the seed spacing listed in the charts for your population. This listed as “inches per seed”.
Also, during start up you may encounter alarms and readouts on the console that do not seem to make sense.
It is critical to troubleshoot these alarms, not only to make sure the planter drive is set properly to hit the target
population, but also to fix incorrect entries in the monitor to eliminate nuisance alarms. For seed monitor
issues, also see the monitor operator manual.
Before going to the troubleshooting charts to remedy seed monitoring system console or population problem,
use the following chart. Finding what is wrong comes from knowing what the planter is actually doing in the
soil. Always dig and observe seed on the ground when checking populations.

The following illustration shows rear cross sections of the seed meter in normal and row-failed conditions.
1. Is the spacing on the ground
correct?
No
Check the ground drive transmission and range sprocket selections, or the
population settings on a hydraulic drive unit.

the
actual population, or is the
reported population too high by
a factor of 2?
No Go to step 3.
Yes
An incorrect row spacing value entered in the seed monitor can cause this.
Example: 15 inches instead of 30 inches, Correct the row spacing error on
the monitor.
The system can also be off by a large factor if incorrect range sprockets are
installed. Check seed rate charts against range and transmission sprockets
on the planter.
3. Is the population on the monitor
close to the target population?
No Check seed rate charts against transmission sprockets selected.
Yes
If slightly under, see “ Seed Population Too Low ” on page 82. If slightly
over, see “ Seed Population Too High ” on page 84.
