TROUBLESHOOTING
Problem
Row unit floats out of soil
Planter pulls to one side
Damage/Breakage of blade
shaft, coulter arm and or blade
Bending or breakage of
fertilizer tube
Fertilizer splatter
Cause
Insufficient down pressure
Planter frame not level for and
aft
Soil too hard/compacted
2959 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
Tube/nozzle adjusted too low
Heavy rock conditions
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
Raise nozzle to a minimum ½”
above soil
Install 2959-104 spring loaded
injection kit
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.
