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 console to eliminate nuisance alarms.
For console issues, see console 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.
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.
Yes
Go to step 2.
2. Is the reported population

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 console can cause this.
Example:
If 15 inches has been entered instead of 30 inches, correct the
row spacing error on the console.
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 console
close to the target population?
No
Check seed rate charts against transmission sprockets selected.
Yes
