47. The Small Seeds Rate Handle scale is a percentage
of meter opening, and its effect is linear near scale
center. Calculate a new scale setting based on the
test.
48. Set the Small Seeds Rate Handle to the new scale
setting.
49. You may want to repeat calibration procedure at the
new setting if your results varied greatly from the
Seed Rate Chart, or if you must operate near the
ends of the Seed Rate handle scale (0-20 or
90-100).
50. Check that your end-wheel tires are 7.5 x 20, 4-ply
Rib Implement and properly inflated. See “Tire
Inflation Chart” in Operator Manual.
51. With calibration complete, store calibration crank, re-
engage lock-out hub, reinstall fertilizer chain (if
removed) and reconnect seed hoses.
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 rate
slightly to compensate for field conditions.
Small Seeds Row Shut-Off
If alternate row spacing is required for small seeds,
optional plugs (see Operator Manual) are available to
block flow inside the seed box tray.
Clean-out seed. The seed box must be empty prior to
inserting plugs. See “Small Seeds Box Clean-out” in
Operator Manual.
52. 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.
53. 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.
54. Review seed rate settings prior to planting. Perform
calibration calculations with the actual active row
count.
When removing plugs to restore rows to operation, be
sure to not disturb a factory-installed plug.
