NOTE: To extend the life and maximize efficiency of the
finger pickup meter and the brush-type seed meter, sprin-
kle 1 teaspoon of powdered graphite on top of the seeds
in the hopper, see Figure 3-3. The graphite will work its
way down to lubricate the meter mechanism.

To install the seed disc onto the meter hub, turn the disc
counterclockwise while tightening the two wing nuts that
retain the disc. After the wing nuts are tight make sure the
seed disc has only slight resistance when it is rotated
counterclockwise.
Clean seed should be used to assure accurate seed me-
tering. Brush meter seed discs should be removed and
checked daily for buildup of foreign material in the seed
meter or brushes. Foreign material, such as hulls, stems,
etc., may affect seed delivery.
Refer to the Planting Rates for Brush Meters in “Section
5 Planting Rate Adjustments” on page
30 for adjusting
the planting rates and sprocket combinations.
Read and follow the seed manufacturers’ recommenda-
tions when using seed treatment.
