Removing a Seed Disk
Refer to Figure 65
1.
Remove rain cover. If seed is present, close
shutter
to prevent more seed from entering meter.
Attach funnel (page 78) or place a tarp under the row
to collect seed.
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 or to control flow to
tarp. Open shutter to release remaining seed up to
wing tube.
4. Clean seed from all brushes. Clean disk seat ( in
Figure 62 page 59), so that new disks can seat fully.
Inspect brushes for excess wear and damage. See
“Meter Brush Maintenance” on page 80.
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 82.
6. Re-install the rain cover (page 57).
Row Unit Shut-Off
Skip-row operations, such as switching from 110 cm
twin- or triple-row to 110 cm single-row, requires shutting
down unused rows.
Shutting off seeding at a row involves 4 to 6 steps:
1. Identify the rows to shut off (page 61).
2. Fully close seed inlet shutter (page 61).
3. Replace seed disk with blank disk (page 61).
4. Lock up row unit to reduce wear (optional, page 61).
5. Reset marker extension (Option, page 120).
6. Reset monitor active row pattern and row spacing to
avoid nuisance alarms (see Monitor manual).
Note: Meter drive is not disabled on 25AP row units
during shut-off.
