Seed Disk Removal
1. Remove the rain cover. If seed is present, close
the seed inlet gate to prevent more seed from
entering the meter.
2. Attach the seed container, stored under the
walkboard, to the seed meter or place a tarp
under the row unit to collect the seed.
3. Hold seed disk and rotate the seed meter clamp
(1) counterclockwise 45° to release the disk.
4. Tilt the top of the seed disk toward the meter and
slowly remove the disk, allowing seed to collect
in the funnel on the tarp.
5. Open the seed inlet gate to release the
remaining seed.
6. Clean the seed from all brushes. Clean disk seat
so new disks can seat fully. Inspect brushes for
excess wear and damage. See “ Seed Meter
Brushes Maintenance
” on page 56.
7. Inspect removed disks for excess wear and
damage. Set aside any disks requiring
replacement. See “ Seed Disk Maintenance ” on
page 58.
8. Clean seed disks and place in storage.
9. Re-install the rain covers.
Row 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.
1. Identify the 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 front (short mount)
rows.
On single-row planter with mid-length
mounts, any rows may be locked up.
2. Fully close the seed inlet gate to prevent meter
pressurization air from leading into the seed air
system. This can result in lower pressures in
other rows, which can cause skips.
To close the seed inlet gate, squeeze the tabs (1)
and move the gate to the “X” setting (2). Release
the tabs.
The gate also stops seed flow from a row as
soon as the meter is empty. Bulk seed flow to the
row falls to zero as soon as the seed backs up to
the air release vent at the top of the meter.
3. Clean out the meter. Remove the seed disk and
install a blank disk.
A blank disk is necessary in row shut-off to
maintain consistent meter pressurization
and to minimize wear on the seed disk and
brushes.
Irregular Seeding Risk
Always use a blank disk in a shut off row.
Operating with no disk, or with a seed disk
but no seed, destabilizes the regulated
airflow, particularly at rows with pressure
sensor lines.
