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).
Air release vent plugged
Remove the seed delivery hose and clamp from the
two halves of the screen cone and remove the air
release screen for inspection. Wash or blow out the
screen as needed.
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.
