Airbox Troubleshooting
Problem
Cause
Fix
Single row doesn’t fill or keep up
with other rows.
Y-tube is bent/angled off feed pipe.
Loosen and rotate pipe so the bend is
straight down and Y-tube is not pointing to
front or rear of air pipe.
Both rows on one meter outlet low
or not keeping up with other rows.
Note: This is more likely to occur
on end outlets.
Blockage in air slot in top of airbox.
Clear by using a long slim tool and taking
hose off hose outlet or clean-out door.
Note: May be necessary to take top off
airbox to clear debris 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.
Add seed.
Fan speed too high.
Adjust fan speed.
Extremely high populations may require
slightly reduced field speed.
1, 2, 3, or more outlets fail.
Note: 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 many rows,
with heavily treated seed.
Seed treatment sticky.
Add talc to seed to dry out seed treatment.
