PROBLEM Probable cause Remedy
Inadequate
numbers of seeds
and or uneven
distribution in the
line of seeds, with
un-seeded spots
or two seeds
together
Inadequate plate or seed disc
for the density selected.
Determine the position of the levers
in the gearbox and the correct seed
plate for type of seed and doses
desired.
Seeds of very different types
Use calibrated seeds.
The size of the seed does not
match the size of the holes in
the seed plate.
Use the seed plate with holes
according to the size of seed.
Excessive speed while planting.
The normal operating speed while
planting should not exceed 10
km/h.
Holes of the plates stuck with
foreign object.
Clean the seed plates.
Wrong regulation and setting of
the Seed triggers
Regulate the seed scrapers and
triggers
Not enough
planting depth
Worn opener discs
Adjust the depth control registration
Replace discs.
Compacted and hard soils
Register the planting unit´s
pressure(springs of the
parallelogram)
Install No-till planting disc.
Covering of the
wrong furrow
Wrong regulation of the
covering- closing wheels
Correct the pressure and angle of
wheel operation.
Seeds appear in
the head ends
The contact drive wheel is too
low; it still is in contact with the
ground while the planter is lifted.
Actuate on the contact drive wheel
adjusting its height
(in this case lifting it)
Irregular planting
and less than the
doses selected
The contact drive wheel is too
lifted and produces slippage.
Work on the registration of the
wheel´s height
The contact drive wheel
performs with low pressure over
the ground and produces
slippage
Increase the pressure of the spring
of the contact drive wheel.
Incorrect tire pressure of contact
drive wheel produces slippage
Inflate to 30 lbs/square inch
2,1 kgs/ cm2
A marker does not
descend
The elevation cycle of the other
marker has not been completed
Always elevate the markers to the
final position, this will allow the
sequence valve to work correctly
The marker is lifted
while working
An elevation cylinder of the
planter has not closed properly
Always lower the planter to the
lowest position, until cylinder stop
has been reached
Uneven elevation,
or not elevation of
the planter al all
There is air inside the elevation
cylinders
Lift TOTALLY the planter and keep
it in this position using the lever for
2 or 3 minutes to purge the system.
