Excessive
NH
3
loss to
atmosphere
(all rows)
Application depth too shallow Check/adjust tractor hitch (page 43), lift-assist spacers
(page 43) and gauge wheel height (page 91).
Coulters set too deep; lifting tines Reduce coulter depth to tine depth (page 86).
Insufficient sealing Adjust sealers (page 87). Test running dry. Try multiple
settings on different rows at the same time if the adjustment
needed is not obvious.
Check applicator front-to-back level.
Application rate too high for soil or
weather conditions
Consult with agronomist on optimal rate and conditions.
Field speed too high Slow down.
NH

loss to
atmosphere
(some rows)
Wings not level Check tire pressures.
Check wings level (page 136).
Fold cylinders locked in Neutral, and
unable to follow terrain
Set fold/lift circuit to continuous Extend (unfold/lower) for
field application.

Plugged tine See “Clearing Plugged Tines” on page 120.
If tines are plugging frequently, check: coulter setup,
application depth, tine wear. Field conditions and weather
may also be unsuitable at the moment.
Disconnected delivery or vapor line Treat this as tine plugging (page 120) until the cause is
determined. If the cause is tall tough field trash, consider
re-working the field if disconnects are frequent.
Sealer mis-adjusted or failed (such
as a broken spring)
Check sealer. Adjust (page 87) or repair.
Rows in tractor tracks too shallow Reset tractor wheel spacing to avoid rows.
Tines
plugging
frequently
Tines worn Replace worn tines.
Field too wet Wait for drier conditions.
Tractor rocking backward during
stops, or lift sequence pushing tines
backward
Refine stopping and/or lifting technique to avoid reverse
tine motion.
Sealers
plugging
Conditions too wet. Wait for drier conditions.
Too much pressure on row-units. Reduce spring pressure.
Sealers running at an angle Adjust sealers to run straight.
Coulters set too deep, bring up
excess dirt and moisture.
Check coulter adjustment.
Fertilizer Applicator not level from
front to rear
Check applicator front-to-back level (page 43).
Failed bearings Replace bearings.
