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 4 Adjusting
Planting Rates” on page 14 for adjusting the planting
rates and sprocket combinations.
IMPORTANT: To extend the life and maximize efficien-
cy 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.

Troubleshooting” on page 25 & “Section 7 Mainte-
nance” on page 28.
