Airbox Troubleshooting
Speed
Reading
Doesn’t Match
Tractor
Monitor speed reading will only match tractor
with planter lowered.
If speeds don’t agree during planting (with planter lowered),
re-calibrate radar speed sensor with planter lowered.
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,
or use side access doors.
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, butterfly valve.
Out of seed.
Add seed.
Single or multiple hoses
plugging just ahead of airbox.
Fan speed too high/too low.
Check/adjust fan speed, butterfly valve.
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 or butterfly valve.
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.
Incorrect airbox air slot to seed
chamber.
Contact Great Plains Service dept. for
assistance.
Little or no seed to many rows,
with heavily treated seed.
Seed treatment sticky.
Note:
Do not use liquid seed
treatments.
Add talc to seed to dry out seed treatment.
