Unable to adjust
air pressure low
enough.
Lower limit reached in DICKEY-john

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
ground from a
single row
Bottom of seed tube damaged.
Replace seed tube. Avoid setting 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.
System is unable
to automatically
control air meter

Problem Cause Solution
Problem Cause Solution
Single row doesn’t fill or keep
up with other rows.
Y tube is bent/angled off feed pipe.
Loosen pipe and spin so the bend is straight down
and Y-tube is not pointing to front or rear of air pipe.
Drop tube to meter is too long,
causing seed to pool and plug hose
or Y-tube.
Shorten hose (with planter raised, but row units
lowered, to ensure hose is not too short).
Both rows on one meter outlet
low or not keeping
up with other rows.
Blockage in air slot in top of airbox.
Clear by using a long skinny tool and taking hose
off through hose outlet.
It may be necessary to take top off airbox or use
side access doors to clear junk from slot.
Bad hose routing between delivery
hose and airbox on wing.
Correct hose routing.
Multiple rows fail for lack
of seed.
Fan speed too high/too low. Check/adjust fan speed.
Out of seed. Add seed.
Single or multiple hoses
plugging just ahead of airbox.
Fan speed too high/too low. Check/adjust fan speed.
Possible air leak.
Check for air leak downstream between box and
top of meter.
All rows fail.
Lack of seed. Fan speed too high. Adjust fan speed.
Extremely high populations may require slightly
reduced field speed.
1, 2, 3, or more outlets fail.
Outlets can be side-by-side or
random. Plugging may also
move from one outlet
to another.
Foreign matter in seed chamber in
bottom of airbox.
Clean out seed chamber.
Little or no seed to a lot of
rows with heavily treated
seed.
Seed treatment sticky.
Add Ezee Glide Plus to seed to dry out seed
treatment.
Treatment mixed unevenly and
plugging outlets.
Clean out seed. Re-mix.
