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 98) 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 91 page 76), so that new disks can seat fully.
Inspect brushes for excess wear and damage. See
“Meter Brush Maintenance” on page 101.
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 103.
6. Re-install the rain cover (page 74).
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 (page 78).
2. Fully close seed inlet shutter (page 78).
3. Replace seed disk with blank disk (page 78).
4. Lock up row unit to reduce wear (optional, page 78).
5. Reset marker extension (Option, page 165).
6. Reset monitor active row pattern and row spacing to
avoid nuisance alarms (see Monitor manual).
7. Shut off fertilizer drop lines (Option, see Seed and
Fertilizer Rate manual 401-651B for details).
Note: Meter drive is not disabled on 25AP row units
during shut-off.
