Removing a Seed Disk
Refer to Figure 66
1.
Remove rain cover. If seed is present, close
shutter
to prevent more seed from entering meter.
Attach funnel (page 75) 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 63 page 56), so that new disks can seat fully.
Inspect brushes for excess wear and damage. See
“Meter Brush Maintenance” on page 77.
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 79.
6. Re-install the rain cover (page 54).
Row Unit Shut-Off
Skip-row operations, such as switching from 110 cm
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 58).
2. Fully close seed inlet shutter (page 58).
3. Replace seed disk with blank disk (page 58).
4. Lock up row unit to reduce wear (optional, page 58).
5. Reset marker extension (Option, page 111).
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.
