Troubleshooting
Planting Rate Problems
When starting up with a new implement name, a new
crop or a new population it is important to physically
double check what the monitor is reporting in the cab by
digging seeds. This is to verify that you are set up
correctly to plant the desired population. Do not rely
solely on the population reported by the DICKEY-john
®
monitor.
Also during start up it is common to encounter alarms
and readouts on the DICKEY-john
®
console that don’t
seem to make sense. It is critical to troubleshoot these
alarms not only to make sure the implement name drive
is set properly to hit the target population, but also to fix
incorrect entries in the DICKEY-john
®
monitor to
eliminate nuisance alarms.
Before entering the troubleshooting charts to remedy a
monitor or population problem, it is helpful to use the
following flowchart to get a handle on what may be
wrong. The basis for finding what is wrong comes from
knowing exactly what the implement name is actually
doing in the soil. Always dig or 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. See also “ Population Too Low ” or
“ Population Too High ” in the troubleshooting charts.
Yes: Go to step 2.
2. Is the reported population
1
/
2
the actual 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 DICKEY-john
®
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 implement name.
3. Is the population on the
screen close to the target
population?
No:
Check seed rate charts against transmission sprockets selected. See
“ Population Too Low ” or “ Population Too High ” in the troubleshooting charts.
Yes:
If slightly under, see “ Population Too Low ” if slightly over, see “ Population
Too High ”.
For seed monitor issues, see also the DICKEY-john
®
Planter/Drill Control User Manuals,
“ TROUBLESHOOTING & ALARMS ” section.
Suggested Furrow Check:
Plant a short distance and dig 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 is listed as “inches per seed”.
