Seed Population Troubleshooting
Problem Cause Solution
Overall
population
alarms.
False alarms or actual rate errors due to
monitor setup with incorrect (active) row
count or spacing
Review planter configuration and monitor setup.
Incorrect cell count
Replace seed disks with correct disks, or reset rate for current
disks, if within range.
Improper gap on speed sensor
Check speed sensor on planter for
1
/
16
to
1
/
8
inch (1.6 to 3.2 mm)
gap from the wheel. An improper gap can cause erratic speed
signal causing the monitor to falsely report an improper planting
rate.
Incorrect speed sensor constant Perform speed calibration according to the monitor manual.
Low population
bands just after
turns.
Insufficient oil to fan, meter pressures
low, seeds falling from disks
Perform end-of-pass marker and lift operations separately. If
already performing separately, reduce marker speed, and/or lift
more gradually.
Mismatch
between
reported and
furrow
population.
Small seeds (example: milo) are not
reliably sensed in the seed tube
Run with rain covers in place to minimize ambient light intrusion.
Use the population adjustment factor in the monitor system to
compensate for missed seeds. For example, change the Population
Adjustment values from 100% to 130% as needed. Remember to
set this value back to 100% for large seeds.
Seed tube sensor is not counting all
seeds
Clean the seed tube of graphite and dust buildup with seed tube
brush. Replace sensors that malfunction.
Seeds or revolution value in the monitor
setup does not match disk cell count
Correct the value in a setup screen or install correct cell count disk.
Unable to
adjust air
pressure low
enough.
Lower limit reached in software At User Level 2, reduce the controlled air lower limit in the software.
Fan speed too high, vane rotated to
maximum
Reduce the fan speed.
Seed too
shallow or
scattered on
the ground
from a single
row.
Bottom of seed tube damaged
Replace seed tube. Avoid setting the planter straight down. Use
forward motion when lowering.
Row not penetrating in tire tracks Increase down force on parallel arm springs.
Opener depth too shallow Change side depth wheel setting.
Twin rows were
timed but
became out of
time.
Timing will change when a population
change has been made
Re-time meters from the population based timing chart.
Chain has jumped Check sprockets and chain for excessive wear or rusty, stuck links.
Excess seed
remaining.
Field size different After ruling out population problems, re-check geography.
Excessive gaps between planter passes Adjust marker.
Incorrect speed calibration
Perform speed calibration using the monitor manual.
Seed
consumption
too high.
Field size different After ruling out population problems, re-check geography.
Excessive overlap, irregular shaped field Adjust marker.
Incorrect speed calibration
Perform speed calibration using the monitor manual.
Rows not
planted.
If not detected by the seed monitor,
check for plugged seed tube
Lift the planter, expose bottom of seed tube, and clean out.
