Problem
Cause
Solution
Overall Low
Population
Incorrect seed rate.
Using
Seed Rate Manual
, check:
•
seed disc selection,
•
Range/Transmission sprocket setup, and
•
tire size and inflation.
” on page 13 for the part
number of the Seed Rate Manual.
Empty pockets on disc (skips) due to insufficient air
pressure.
Methodically increase the Meter pressurization.
Empty pockets on disc (skips) due to sticky seed
treatments not allowing seed to rapidly fill the
pockets.
Increase seed lubricant.
Empty pockets on disc (skips) due to rough field
conditions causing seeds to fall from the discs.
Decrease field speed or increase the air pressure in the
meter.
Empty pockets on disc (skips) due to seed pool too
low, and seeds are not filling every pocket on the
disc.
Open shutter one notch.
Empty pockets on disc (skips) due to disc speed too
high, and pockets are not filling.
Decrease field speed or change to a higher cell count disc.
Empty pockets on disc (skips) due to singulation
(4 tufted) brush too aggressive.
Check for matted, stuck together fibers. Wash, scrape clean,
or replace as needed.
Empty pockets on disc (skips) due to seed too big
for pocket.
Select the correct disc for the seed size.
Seeds are not falling from disc, and get carried past
drop zone. Static electricity can cause small,
lightweight seeds to cling to the pocket 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.
Air pressure too low, as confirmed by gauge.
Increase fan speed or reduce butterfly valve setting.
Air pressure too low, but gauge reading is within
range or reading high.
•
Inspect the
1
/
4
inch sample lines from the row units
up to the sensor chamber for leaks (page 82),
•
Make sure all non-planting rows have blank discs
and shutters are closed (page 75),
•
Re-zero the gauge with the fan off (page 82),
•
Check gauge vent line for kinks, pinches or
plugging (page 82).
Excess field speed.
Plant within speed ranges recommended in
Seed Rate
Manual
.
Incorrect seed rate.
Using
Seed Rate Manual
, check:
•
seed disc selection,
•
Range/Transmission sprocket setup, and
•
tire size and inflation.
” on page 13 for the part
number of the Seed Rate Manual.
Incorrect speed sensor constant.
Perform speed calibration per planter monitor manual.
Incorrect magnetic speed sensor gap.
Check and adjust (page 94).
(Option) Incorrect radar speed sensor angle.
With planter lowered, check radar speed sensor angle per
DICKEY-john recommendations.
Pass gaps too large.
For GPS, check planter size programmed.
Actual field size is different.
Population may be correct, and calculations are not.
Planter monitor reporting excess area.
Readings can vary with conditions (wheel slippage, and
effective rolling radius in soft soils) and planting patterns.
