Sprocket Indexing (Stagger)
If you are planting:
• finger-metered,
• twin-row crops,
• at seed interval spacings above 6
1 ⁄
2
inches (16.5 cm),
you can synchronize each pair of adjacent meters in a
twin row so that you achieve the maximum seed-to-seed
spacing between the units of the pair.
Refer to the Seed Rate manual for details.
Finger Meter Inserts
Refer to Figure 114
The backing plate is equipped with an “A” insert . In
tests, this insert provides the best performance in most
seed sizes. However, there are two alternative inserts
that can be used. Before changing to a different insert,
please consult with a Great Plains service representative
for a recommendation.
The identification of the insert type is molded into the
back of the insert.
Machine Damage Risks:
Be cautious in using seed treatments, additives, and other
chemicals when possible. They can cause meter performance
problems and premature wear to meter parts. Avoid the use of
graphite with the precision meter. If graphite must be used, use
Precision™ Planting graphite or Great Plains graphite which
is less abrasive. Generally, seeds coated with Maxi or similar
coatings, such as Captan, benefit from graphite. Always store
meters in a dry, secure place. Moisture, temperature,
nest-building insects and rodents can create problems. Always
pay attention to your seed monitor and operating manual.
Monitor the amount of seed you are planting compared to your
expectations. Always investigate abnormalities!
