Finger Pickup Corn Meter
Larger grades generally plant more accurately at the high end of ground speed range than smaller grades. Higher than optimum
speeds may result in population rate increase or higher incidence of doubles, particularly with small seed. Medium round corn seed
is most desirable for planting accuracy at optimum speed.
Finger Pickup Oil Sunflower Meter
Larger grades generally plant more accurately at the high end of ground speed range than smaller grades. Higher than optimum
speeds may result in population rate increase or higher incidence of doubles, particularly with small seed. No. 3 and/or No. 4 size oil
sunflower seeds are recommended for use in finger pickup seed meters equipped with oil sunflower fingers. No. 1 and/or No. 2 size
confectionery sunflower seeds are recommended for use in finger pickup seed meters equipped with corn fingers.
Brush-Type Seed Meter (Soybean, Milo/Grain Sorghum, Acid-Delinted Cotton)
Rate charts are given in seeds per hectare as well as seed spacing in centimeters rounded to nearest tenth of a cm. Because
of large range in seed size, pounds per hectare is not a suggested method of selecting transmission settings. Smaller size seed
pounds per hectare may be below what was expected and large seed pounds per hectare may appear above expectations. To
determine pounds per hectare, use formula given in “Determining Pounds Per Hectare (Brush-Type Seed Meter)” in “Check Seed
Population” in Machine Operation section of this manual.
NOTE: Planting speed can affect actual seeding rate. Make a field check and adjust transmission setting to obtain desired
seed drop.
NOTE: Seed population per hectare with 35 cm rows double rate for 70 cm rows, at listed sprocket combination. See
following pages.
NOTE: Half Rate (2 to 1) Drive Reduction Package may be required to obtain desired population and seed spacing when
planting 15" row soybeans or other crops. Half Rate Drive with brush-type seed meters reduces planter transmission
speed. Seeding rate will be approximately 50% of chart reading when using Half Rate
(2 To 1) Drive Reduction Package.
EXAMPLE: 70 cm row spacing using 60 cell seed discs in brush-type seed meters.
80,928 ÷ 2 = 40,464 Population (6.5 cm Seed Spacing x 2 = 13 cm Seed Spacing)
VACUUM
NOTE: 22, 28, and 44 tooth drive sprockets are NOT applicable to all rate charts. Check chart titles to ensure proper rate
chart is selected. 22 tooth sprocket requires 114 pitch No. 40 chain. 28 tooth sprocket requires 118 pitch No. 40 chain. 44
tooth sprocket requires 126 pitch No. 40 chain.
NOTE: DO NOT USE 44 tooth sprockets (60 cell soybean discs) with Dry Fertilizer Package or Liquid Fertilizer Package.
