Small Seeds Row Shut-Off
Refer to Figure 20
If alternate row spacing is required for small seeds,
optional plugs are available to block flow inside the seed
box tray.
1. Cleanout seed. The seed box must be empty prior to
inserting plugs. See “Small Seeds Box Cleanout”
on page 23.
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 and marker extension
prior to planting.
When removing plugs to restore rows to operation, be
sure to not disturb a factory-installed plug. Figure 20
