Row Shut Off
Using optional plugs, seed flow can be shut off for indi-
vidual main box or Small Seeds box rows, but not for Fer-
tilizer rows. Using optional pins, unused rows can be
raised and locked up to reduce wear.
Main Seed Row Shutoff
If alternate row spacings are desired, the unused rows
can be shut off with optional plugs (page 85).
1. Clean-out seed. The seed box must be empty prior
to inserting plugs. See “Main Seed Box Clean-Out”
on page 61.
2. Insert one plug at each row to shut off. Verify the
seed hose path before inserting the plug, as some
hoses do not make a strictly vertical drop to their row
units.
3. Review seed rate settings prior to planting. Perform
calibration calculations with the actual active row
count.
4. Review marker extension setting. Drill centerline may
have shifted, and correct extension values are likely
to have changed and may differ on each side (and
differ for opposing vs. concentric passes).
Small Seeds Row Shut-Off
If alternate row spacing is required for small seeds,
optional plugs (page 86) are available to block flow inside
the seed box tray.
1. Clean-out seed. The seed box must be empty prior
to inserting plugs. See “Small Seeds Box Clean-
Out” on page 62.
2. Before installing plugs, inspect the seed boxes for
existing factory-installed plugs. These are blocking
extra unused seed ports. You may want to identify
these plugs with an indelible marker.
3. Insert one plug at each row to shut off. Verify the
seed hose path before inserting the plug, as some
hoses do not make a strictly vertical drop to their row
units.
4. Review seed rate settings prior to planting. Perform
calibration calculations with the actual active row
count.
5. Review marker extension setting. Drill centerline may
have shifted, and correct extension values are likely
to have changed and may differ on each side (and
differ for opposing vs. concentric passes).
When removing plugs to restore rows to operation, be
sure to not disturb a factory-installed plug.
