Removing a Seed Disk
Refer to Figure 51
1. Remove rain cover. If seed is present, close
shutter
to prevent more seed from entering meter.
Attach funnel (page 66).
2. Hold seed disk in meter. Rotate disk clamp coun-
terclockwise 45
°
to release disk.
3. Tilting top of disk toward meter, slowly remove disk,
allowing seed to collect in funnel. Open shutter to
release remaining seed up to wing tube.
4. Clean seed from all brushes. Clean disk seat ( in
Figure 48 page 48), so that new disks can seat fully.
Inspect brushes for excess wear and damage. See
“Meter Brush Maintenance” on page 68.
5. Inspect removed disks for excess wear and damage.
Set aside any disks requiring replacement. Clean
other removed disks and place in storage. See
“Seed Disk Maintenance” on page 70.
6. Re-install the rain cover (page 46).
Row Unit Shut-Off
Skip-row operations, such as planting from every other
row when switching from 30in twin-row to 30in sin-
gle-row, requires shutting down unused rows.
Shutting off seeding at a row involves 4 to 7 steps:
1. Identify the rows to shut off.
2. Install outlet plugs in the seed box.
3. Fully close seed inlet shutter (always done).
4. Replace seed disk with blank disk (always done).
5. Lock up row unit to reduce wear (optional).
6. Reset marker extension (if used, page 100).
7. Reset monitor active row pattern and row spacing to
avoid nuisance alarms (always done).
Note: Meter drive is not disabled on 25AP row units dur-
ing shut-off.
