Removing a Seed Disk
Refer to Figure 107
1.
Remove rain cover. If seed is present, close
shutter
to prevent more seed from entering meter.
Attach funnel (page 102).
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 104 page 82), so that new disks can seat fully.
Inspect brushes for excess wear and damage. See
“Meter Brush Maintenance” on page 104.
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 106.
6. Re-install the rain cover (page 80).
Sprocket Indexing (Stagger)
If you are planting:
• twin-row crops,
• at seed interval spacings above 6
1 ⁄
2
inches (16.5cm),
you can synchronize each pair of adjacent meters in a
twin row so that you achieve the maximum seed-to-seed
spacing between the units of the pair.
Refer to the Seed Rate manual for details.
