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 opener
bounce.
2. Always pay attention to your drill monitor. Compare
actual seed usage to your estimates.
3. Fine-tune your drill 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 opener itself.
Brush
Refer to Figure 79
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.
Be cautious in using seed treatments, additives and other
chemicals when possible. They can cause meter perfor-
mance 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 do not need
graphite. Other seed coatings such as Captan generally
benefit from graphite.

Always store meters in a dry, secure place. Moisture, tem-
perature and mice can create unintended problems.
Always pay attention to your seed monitor, operating manu-
al and monitor the amount of seed you are planting com-
pared to your expectations. Always investigate
abnormalities!
