Overall low
population
(continued)
Empty cells in seed disk due to seed
pool too low, and seeds not filling
every cell on the disk
Open seed inlet gate one notch.
Empty cells in seed disk due to disk
speed too high, and cells not filling
Decrease field speed or change to a higher cell count
seed disk.
Empty cells in seed disk due to tufted
brush too aggressive
Check for matted, stuck together fibers. Wash, scrape
clean, or replace as needed.
Empty cells in seed disk due to seed
too big for the cell
Select the correct disk for the seed size.
Seeds are not falling from seed disk
and are 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 Easy Glide Plus and/or
more thoroughly mix the lubricant into the seed (page 31).
Air pressure too low, as confirmed by
gauge
Increase fan speed.
Air pressure too low, but gauge
reading is within range or reading
high
Inspect the lines from the row units to the sensor chamber
for leaks.
Make sure all non
-
planting rows have blank disks and
gates are closed.
Re
-
zero the gauge with the fan off.
Check gauge vent line for kinks, pinches, or plugging.
Low fan speed - meter starvation due
to meter pressurization not leaving
enough air for seed delivery
Increase fan speed.
Tire pressure in contact drive wheel
incorrect
Check for correct tire pressure (page 87).
Excess field speed
Plant within speed ranges from seed rate chart.
Pass gaps too large
Check marker extension (page 48).
For GPS, check planter size programmed.
Actual field size is different
Population may be correct, and calculations are not.
Seed monitoring system console
reporting excess area
Readings can vary with conditions (wheel slippage, and
effective rolling radius in soft soils) and planting patterns.
Improper gap on speed sensor
Check speed sensor on planter (page 12). Adjust as
needed.
Incorrect speed sensor constant
Perform
SPEED CALIBRATION
operation. See
the
console manual for instructions for your seed
monitoring system.
