Seed Population Too High
Seed Delivery Problems
Problem Cause Solution
Overall high
population.
Incorrect seed rate Check seed rate charts.
Incorrect ground drive transmission or
range sprockets or shafts used
Check transmission sprocket or range sprocket tooth counts and
driving/driven locations.
Two seeds per cell in the seed disk due
to excess meter pressurization
Decrease the controlled air to the meter. See “ Fan and Meter
Pressurization ” on page 32.
Two seeds per cell in the seed disk due
to cells too large for the seed
Select a disk with smaller cells.
Air meter pressure too high due to
pressure sensor not zeroed properly
Re-zero the air pressure with the fan off. Make sure the displayed
pressure reads 0.00.
Air pressure too high, false information
driving the software
Compare the air pressure reported on the monitor to the mechanical
gauge. If they do not match:
• inspect the 1/4 inch sample lines from the row units up to the
sensor chamber for leaks.
• make sure all non-planting rows have blank disks.
• re-zero the air pressure with the fan off.
False alarms or actual seed rate errors
due to monitor setup with incorrect row
count, spacing, or active rows
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 the planter for 1.6 to 3.2 mm (1/16 inch to 1/
8 inch) 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.
Doubles due to incorrect disk for crop or
seed size
Use the recommended disk for crop and seed size.
Sticky seeds, excess seed treatment Increase seed lubricant.
High
population, one
wing.
Ground drive only - left-hand and right-
hand range or transmission setup not
matched
Make sure left-hand and right-hand range and transmission settings
are identical, and that sprockets are on the proper driving/driven
shafts.
High
population,
single row.
Excess meter pressurization causing
doubles
Check gate.
Worn seed drop brush and/or strip
brushes allowing excess seed to pass
Replace worn brushes.
Incorrect seed disk with higher cell count Install correct disk.
Problem Cause Solution
Single row
does not fill or
keep up with
other rows.
Y-tube is bent or angled off feed pipe
Loosen the pipe and spin so the bend is straight down and the Y-
tube is not pointing to the front or rear of the air pipe.
Drop tube to the meter is too long
causing seed to pool and plug the hose
or Y-tube
Shorten the hose (with planter raised, but row units lowered, to
make sure the hose is not too short).
Both rows on
one meter
outlet low or
not keeping up
with other
rows.
Blockage in the air slot in top of airbox
Clear by using a long skinny tool and taking hose off through the
hose outlet.
It may be necessary to take the top off the airbox or use side access
doors to clear junk from the slot.
Bad hose routing between delivery hose
and airbox on wing
Correct the hose routing.
