1. With the fan off, check the meter pressurization
on the seed monitor. Re-zero as needed (see
seed monitoring system console manual).
2. Determine the recommended fan rpm.
3. Determine the recommended meter pressurization
(see Seed Rate manual).
4. Start the fan. Gradually increase fan rpm using
the tractor hydraulic flow control for the circuit.
5. Check that at least a small amount of pressure is
being sensed at the meters and meter
pressurization is near the suggested value.
6. Start delivery fan.
7. Fill the meters:
a. With the fan running, put the tractor in park and
set the park brake.
b. Walk behind the wings, remove several rain
covers from the seed meters, and check for seed
in the meters by looking through the clear disks.
Rows to check are those with longer hoses and
sharper hose bends.
If a meter runs completely out of seed (starved),
back-pressure to the air box manifold may
prevent prompt refill. To fill a starved meter, close
the seed inlet gate for about 15 seconds, then
restore it to the original setting.
8. Fill the disk pockets with seed:
a. For electric drive and hydraulic drive, run a FILL
DISK operation.
b. For ground drive, use one of these options:

With RSM clutch switches off, use a 7/8 inch wrench
to rotate the wing meter system drive shaft 1 1/2 turns
(top forward).

Lower the planter and plant for a short distance. It
takes a few feet before seed begins to drop from the
meters.
9. Check control air system pressure. With meters
and disks filled, meter pressurization should be
at target value.
10. Begin planting. Troubleshoot any obvious
problems or alarms.
11. During the first pass, take note of the average
populations reported on the seed monitor:

Screen 1 (first row above graphs), Average Overall
Population
If the population is only slightly low, the problem
can be skips (periodic empty disk pockets). If
slightly high, the problem can be doubles
(periodic pockets with double seed). A meter
pressurization adjustment may correct either
condition.
If the reported population varies from the desired
population by a significant amount, preform the
following check:
a. Expose several seeds in each of several rows,
being careful not to disturb their relative
positions.
b. Measure and average the distance between
seeds.
c. Compare the average to the predicted seed
spacing for the population in the Seed Rate
manual.
Any instances of no seed where expected may
be sign of skips. Two seeds at the same place
indicates doubles.
12. Resume planting. During the next pass, note the
following on the seed monitor:

Screen 1 (second row above graphs), Minimum Row
Population

Screen 1 (third row above graphs), Maximum Row
Population
A small variation of population between rows in
normal. However, a row consistently running
lower or higher than the other rows, could
indicate a meter or seed sensor problem that
needs attention. See “ Seed Population
Troubleshooting ” on page 81.
Skips
If everything else is correct, and the overall average
population is running low, or there are gaps when
doing a furrow check, the cause may be seeds falling
out of disk pockets before delivery to the seed tube.
Increase meter pressurization to correct this.
Insufficient meter pressurization, or unusually rough
fields can increase the incidence of empty pockets.
Be sure to rule out other causes, such as skipping
chains, meter starvation, or incorrect meter disks,
before adjusting meter pressurization to reduce
skips. Excess meter pressurization can increase the
chance of doubles.
Meter pressurization can be adjusted with
the planter in motion.
