Removing a Seed Disk
Refer to Figure 110
1. Remove rain cover. If seed is present, close
shutter
to prevent more seed from entering meter.
Attach funnel (page 103).
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 107
page 81), so that new disks can seat fully.
Inspect brushes for excess wear and damage. See
“
Meter Brush Maintenance
” on page 105.
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 107.
6. Reinstall the rain cover (page 79).
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 170).
7. Reset monitor active row pattern and row spacing to
avoid nuisance alarms (always done).
8. Shut off fertilizer drop lines (Option, see Seed and
Fertilizer Rate manual 401-647B for details).
Meter drive is not disabled on 25AP row units during
shut-off.
1. Identify Rows to Shut Off. On twin-row planters,
openers are installed with short and long opener
mounts. If locking up unused rows of a twin-row
planter, shut off the rear (long mount) rows.
On single-row planters with mid-length mounts, any rows
may be locked up.
