General Application Troubleshooting
Problem
Cause
Solution
Excess
Material
Remaining
Field size different.
After ruling out metering problems, re-check geography.
Excessive gaps between applicator
passes.
Gap between opposing pass end trenches should be one row
space (e.g. 30 inches)
Material
Consumption
Too High
Field size different.
After ruling out metering problems, re-check geography.
Excessive overlap
Gap between opposing pass end trenches should be one row
space (e.g. 30 inches). Also check tracks for unintended
re-applications, particularly if relying on GPS mapping.
Tank or system Leak
Suspend application. Check for leaks.
Rows Not
Fertilized
Check for plugged row-unit tube
Stop application. Lift applicator and inspect tines.
No Fertilizer
Flow
Strainer plugged
Close all valves. Inspect strainer (page 128). Clean screen as
needed.
Material run-out
Check tank level.
Tines
plugging
frequently
Tine tips too low for coulter depth
Raise tine weldment.
Coulter blades too worn
Replace coulter blades.
Field too wet
Wait for drier conditions.
Applicator not level from front to rear
Check applicator front-to-back level (page 41).
Tractor rocking backward during stops,
or lift sequence pushing tines backward
Refine stopping and/or lifting technique to avoid reverse coulter
motion in ground.
Excessive
NH
3
loss to
atmosphere
(all rows)
Application depth too shallow
Check/adjust tractor hitch (page 41), lift-assist spacers
(page 41) and gauge wheel height.
Coulters set too deep; lifting tines
Reduce coulter depth to tine depth (page 84).
Insufficient sealing
Adjust sealers (page 86). 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
3
loss to
atmosphere
(some rows)
Wings not level
Check tire pressures.
Check wings level (page 137).
Fold cylinders locked in Neutral, and
unable to follow terrain
Set fold/lift circuit to continuous Extend (unfold/lower) for field
application.
NH
3
loss to
atmosphere
(one row)
Plugged tine
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 118) 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 86) or repair.
Rows in tractor tracks too shallow
Reset tractor wheel spacing to avoid rows.
