Adjusting Finger Pick Up Meter
The finger pick up meter has an adjustable brush. It has
been pre-set to the optimum setting for most seed sizes.
Listed below are some basic guidelines for operating
and adjusting the meter.
General Planting Tips
1.
Optimum planting speed is 4 1/2 to 5 miles per hour.
Excess speed results in poor spacing performance
due to seed tube bounce. Excess speed may also
result in improper depth control due to row unit
bounce.
2. Always pay attention to your planter monitor. Com-
pare actual seed usage to your estimates.
3. Fine-tune your planter by thoroughly checking all
key components including: Keeton™ Seed Firmers,
seed tubes, chains, sprockets, tire pressure, seed
monitor, double disk openers, gauge wheels, clos-
ing wheels, parallel arms and the row unit itself.
Brush
The adjustable brush provides additional flexibility to
accommodate a wide range of seed sizes. Use a flat-
head screwdriver to gently rotate the brush into posi-
tion. Use the general guidelines in the table on the right
to adjust the brush position to your seed size and
shape. The numbers listed correspond to the numbers
printed on the outer housing of your meter.
Population Max Inserts
The Population Max backing plate is equipped with an
“a” insert (or an “R” insert). In tests, this insert provides
the best performance in most seed sizes. However,
there are two alternative inserts that can be used. Be-
fore changing to a different insert, please consult with a
Great Plains service representative for a
recommendation.
Important: Be cautious in using seed treatments, ad-
ditives and other chemicals when possible. They
can cause meter performance problems and prema-
ture 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 abra-
sive. Generally, seeds coated with Maxi or similar
coatings do not need graphite. Other seed coatings
such as Captan generally benefit from graphite.
Always store meters in a dry, secure place. Moisture,
temperature and mice can create unintended prob-
lems.
Always pay attention to your seed monitor, operating
manual and monitor the amount of seed you are
planting compared to your expectations. Always in-
vestigate abnormalities!
