12. Divide by three to obtain a rate per row.
13. Multiply by the active row count to obtain a measured
seed rate.
14. If this figure is different than desired, set your seed
rate adjustment handle accordingly.
15. If the adjustment was more than 5%, it is advisable
to re-test to confirm that the adjustment achieves the
desired field rate.
16. Once a setting is settled on, configure the other
Small Seeds box to match.
When drilling, check seeding rate by noting acres drilled,
amount of seed added to drill and seed level in drill box.
If you are seeding more or less than desired, adjust
seeding rate slightly to compensate for field conditions.
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. See page 129 for ordering information.
1.
Clean out seed. The seed box must be empty prior
to inserting plugs. See “Small Seeds Box
Clean-Out” on page 104.
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.
