Small Seeds Row Shut-Off
If alternate row spacing is required for small seeds,
optional plugs 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 28.
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.
Small Seed Tube Plugs
This plug stops seed flow from the small seeds box at the
top of a seed tube. Order one per row to set inactive.
