PL5700 Planter Table of Contents Index Troubleshooting
Seed Population Too Low
Uneven seed depth.
Excessive field speed Reduce field speed.
Planting conditions too wet Wait until drier weather.
Damaged seed tube Check seed tubes for damage and replace
as needed.
Incorrect coulter depth setting See coulter manual or set unit mounted
coulter.
Excessive or improper row unit down
pressure spring setting
See “ Down-Pressure Adjustment ” on
page 46.
Rough planting conditions Rework the field.
Seed firmer not in place and set to correct
tension
See “ Keeton® Seed Firmer ” on page 53.
Some large singulated
seeds are not
accurate.
Incorrect speed calibration, Sensor
Constant, or Gear Ratio setup
Check and correct speed calibration,
Sensor Constant, and Gear Ratio setup.
Problem Cause Solution
Problem Cause Solution
Overall low
population.
Incorrect seed rate Check seed rate charts.
Incorrect ground drive transmission or
range sprockets used
Check transmission sprocket or range
sprocket tooth counts and driving/driven
locations.
Empty cells in the seed disk due to
insufficient pressure
Increase controlled air to meter (page 34).
Empty cells in the seed disk due to sticky
seed treatments not allowing seed to rapidly
fill the cells
Increase seed lubricant. See “ Close lids
and latches. ” on page 39.
Empty cells in the seed disk due to rough
field conditions causing seeds to fall from
the disk
Decrease field speed or increase air
pressure in the meter.
Empty cells in the seed disk due to seed
pool too low and seeds not filling every cell
in the seed disk
Open the seed inlet gate one notch.
Empty cells in the seed disk due to disk
speed too high and cells not filling
Decrease field speed or change to a higher
cell count disk.
Empty cells in the seed disk due to tufted
brush too aggressive
Check for matted, stuck together fibers on
brush. Wash, scrape, clean, or replace as
needed.
Empty cells in the seed disk due to seed too
big for the cell
Select correct seed disk for seed size.
Seeds are not falling from the seed disk and
get carried past drop zone. Static electricity
can cause small, lightweight seeds to cling
to the cell and not fall out
The graphite component of Ezee Glide Plus
addresses this issue. Increase the amount
of Ezee Glide Plus and/or more thoroughly
mix the lubricant into the seed.
Air pressure too low, as confirmed by gauge Increase fan speed or reduce baffle setting.
