When removing a cover, inspect it for damage and
missing parts. If a cover does not have both latches it
can be lost during transport or field operations. Also,
inspect the knockout brush for wear.
To replace a latch, slide the replacement latch onto
the cover lugs from the meter side, then snap the
other end down over the lugs.
To replace the knockout brush, see “
Knockout
Brush Replacement
” on page 59.
Seed Disk Installation
Incorrect Brush Seating Risk
If planting will not be done within an hour or two
of disk installation, rotate the drive system a
few turns to make sure that the brushes lean in
the correct direction. This will improve meter
performance and reduce air consumption.
Population Risk
Make sure to use the same disk in all active
rows.
1. Check the part number and description on the
seed meter disks against the seed rate chart
data.
2. Before installing, inspect the disks. Do not install
damaged or 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 (see page 57 for
details).
5. Make sure the seed meter clamp (1) is aligned
with the disk seat (2).
6. With the seed cell 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).
With a new meter or new brushes, force the disk
into the brushes to position the seed meter
clamp. The brushes will be trained during initial
rotations.
With slightly used brushes, when a disk is first
clamped, the disk hub may be flat with the disk
seat only on the gate side. The disk should seat
as it first turns. This condition will ease as the
brushes are used.
8. Rotate disks forward after disk installation. This is
particularly important for new brushes.
Brush seating can be done with or without
seed present.
9. Set the seed inlet gate to the setting on the seed
rate chart or to your own developed value.
10. On the console, select the new MATERIAL , seed
disk CELL COUNT , and target population.
See
console manual for instructions for your seed
monitoring system.
11. Reinstall the rain cover.
Seed Disk Removal
1. Remove the rain cover. If seed is present, close
the seed inlet gate to prevent more seed from
entering the meter.
2. Attach the seed container, stored on the planter,
to the seed meter or place a tarp under the row
unit to collect the seed.
