TROUBLESHOOTING
Problem
Row unit floats out of soil
Planter pulls to one side
Damage/Breakage of blade
shaft, coulter arm and or
blade
Fertilizer splatter
Cause
Insufficient down pressure
Planter frame not level for
and aft
Soil too hard/compacted
Fertilizer coulter blade
adjusted too deep
Not an equal number of RH
and LH coulter assemblies
Turning with blades in
ground
Extreme soil conditions
such as very tight soil or
heavy rocks, especially
combined with:
A: speed is too fast
B: blades too deep
C: turning with blades in
ground
Nozzle not aligned with
furrow
Liquid pressure is too high
(PSI) pounds per square
inch
Solution
Increase the tension of the
planter unit down force
springs
Level the frame at 20” frame
height while in planting
position
May have to use a tillage
implement to loosen soil
Raise the coulters.
Coulters could hold planter
out of ground if set too
deep
Assemble equal number of
RH and LH coulter
assemblies
Avoid this
Avoid whenever possible
otherwise:
A: reduce speed
B: run blades only deep
enough to place fertilizer
C: do not turn with blades
in ground
Ensure each nozzle is
directly behind and
centered on the coulter
blade furrow
Recommended PSI is 20 to
30. Adjust and recalibrate
system for different
pressure setting.
