Finger Meter Adjustments
The finger pick up meter has an adjustable brush, and
alternate inserts are available for the backing plate. The
factory-installed insert is the “A” insert.
Optimum planting speed is 4
1
⁄
2
to 5 mph (7 to 8 kph).
Excess speed results in poor spacing performance due
to seed tube bounce. Excess speed may also result in
improper depth control due to row unit bounce.
Always pay attention to your planter monitor. Compare
actual seed usage to your estimates.
Fine-tune your planter by thoroughly checking all key
components including: seed tubes, chains, sprockets,
tire pressure, seed monitor, double disk openers, gauge
wheels, seed firmer, closing wheels, parallel arms, and
the row unit itself.
Finger Meter Brush Adjustment
The brush reduces or eliminates “doubles” (delivering
two seeds per finger), but if set too aggressively can
cause “skips” (delivering no seed on some fingers). As
needed, adjust for minimal doubles and skips.
Note: These instructions describe the current finger pick-
up meter shipped with new Great Plains planters,
which has an integrated adjustment lever for the
brush. If you have the previous model meters, ad-
justed by screwdriver rather than lever, rely on
counting detents to determine the setting. Not all
have 9 detents.
Refer to Figure 10
The adjustable brush provides additional flexibility to
accommodate a wide range of seed sizes. Use lever (L)
to gently rotate the brush into position.
The settings range from 1 to 5 with detents at each half
step, for a total of 9 detents. Although the numbers are
molded into the meter housing, only “1” and “5” may be
visible.To ensure consistency, rotate the lever fully
counter-clockwise (1), and count detents as you advance
it to the desired setting.
Use the general guidelines in the table below 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. If there is a decal on your
meter, its units are seed size in pounds per 80,000 seed
bag. The table below includes seeds per kg and pound.
