Finger Meter Inserts
Refer to Figure 59
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 insert type is molded into the back. Changing inserts
requires meter disassembly.
Meter Reliability Risk:
Be cautious in using seed treatments, additives, and other
chemicals when possible. They can cause meter performance
problems and premature wear to meter parts. If graphite is
used, use Precision Planting
®
planting graphite or Great
Plains graphite, which is less abrasive. Generally, seeds
treated with Maxi, Captan, and similar coatings 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!
Sunflower Meter Configurations
Review the finger pickup meter configuration, based on
the seed size. See chart below. See “Exchanging
Finger Sets” on page 75 for component removal and
installation instructions.
The standard Sunflower configuration is suitable for
#4 and #3 seed sizes. Larger seeds may require the
Corn meter configuration. Using a finger pickup meter for
Confection seeds is not recommended.
