Removing a Seed Disk
Refer to Figure 94
1.
Remove rain cover. If seed is present, close
shutter
to prevent more seed from entering meter.
Attach funnel (page 92).
2. Hold seed disk in meter. Rotate disk clamp
counterclockwise 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 91 page 70), so that new disks can seat fully.
Inspect brushes for excess wear and damage. See
“Meter Brush Maintenance” on page 94.
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 96.
6. Re-install the rain cover (page 68).
Row Unit Shut-Off
Skip-row operations, such as planting from every other
row when switching from 30 inch twin-row to 30 inch
single-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. Fully close seed inlet shutter (always done).
3. Replace seed disk with blank disk (always done).
4. Close seed flow to row at Y-tube (if present).
5. Lock up row unit to reduce wear (optional).
6. Reset marker extension (if used, page 150).
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
during shut-off.
