Finger Pickup Meter
This planter is equipped with a 12 finger mechanical corn
meter see Figure 3-1. Refer to the Planter Rate for Finger
Pickup Corn Meter chart in “Section 5 Adjusting Plant-
ing Rates” on page
28 for adjusting the planting rates and
sprocket combinations.
IMPORTANT: To extend the life and maximize efficiency of
the finger pickup meter, sprinkle 1 teaspoon of powdered
graphite on top of the seeds in the hopper, see Figure 3-
2. The graphite will work its way down to lubricate the
meter mechanism.
For more information on the meter, see “Section 6 Trou-
bleshooting” on page
42 & “Section 7 Maintenance
and Lubrication” on page 45.
