opposing seed delivery. Gently tap on the seed
inlet. Re-open the gate and see if seed now fills
the meter.
4. If no obvious foreign object was the cause of the
bridging, the gate setting may have been too
small for the seed. Verify that this and other
operating rows were at the correct initial gate
setting. If so, reset the gates to the next higher
opening.
Foreign Object Risk
After clearing a bridge, or a delivery
blockage upstream, check the seed pool at
the meter for any debris that might have
been the original cause. Remove the debris
from the meter before planting. This will
eliminate the risk of an object lodging in a
seed pocket and causing on-going skips.
Seed Disk Installation
1. Check the part number and description on the
seed meter disks against the seed rate chart
data.
Population Risk
Make sure to use the same disk in all active
rows.
2. Inspect the disks to be installed. Do not install
damaged or excessively worn disks which can
cause irregular seeding. Chips and cracks can
increase brush wear.
3. Remove the meter rain cover.
4. Inspect the meter and brushes
5. Make sure the seed meter clamp (1) is aligned
with the disk seat (2).
6. With the seed pocket side facing the meter
housing, place the new seed disk on the disk
seat.
7. Rotate the seed meter clamp (1) clockwise 45° to
clamp the disk. The clamp will seat into the seed
disk hub (2).
On a new meter, or with new brushes installed, force
the disk into the brushes to allow the seed meter
clamp to rotate. This condition eases as the brush
fibers are trained during initial rotations.
With slightly used brushes, when a disk is first
clamped, it is normal for the disk hub to be flat with
the disk seat only on the inlet (rear) side. The disk
fully seats as it first turns. This condition eases as the
brushes are used.
Incorrect Brush Risk
Rotate disks forward shortly after disk
installation. If planting is not anticipated
within an hour or two of disk installation,
rotate the drive system a few turns to make
sure that meter brushes lean in the correct
direction. Correct lean improves meter
performance and reduces air consumption.
This step is particularly important for new
brushes.
8. Brush seating may be accomplished with or
without seed present.
9. Reset the seed inlet gate to the setting
recommended by the seed rate chart or to your
own developed value.
10. On the seed monitoring system console, select
the new Material, seed disk cell count, and target
population.
11. Reinstall the rain cover.
