The finger pick-up meter has an adjustable brush, and
alternate inserts are available for the backing plate. The
brush has been pre-set to the optimum setting for most
seed sizes. The factory-installed insert is the “A” insert.
Optimum planting speed is 4
1
⁄
2
to 5 miles per hour
(7.2 to 8 kph). Excess speed causes poor spacing
performance due to seed tube bounce, and may also
cause 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
pickup meter shipped with new Great Plains
planters, which has an integrated adjustment lever
for the brush. If you have added pre-existing finger
meters after purchase, there is some chance that
you may have the previous model meter, adjusted
by screwdriver rather than lever. If so, rely on
counting detents to determine the setting. Not all
have 9 detents.
Refer to Figure 111
The adjustable brush provides additional flexibility to
accommodate a wide range of seed sizes. Use lever
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. The factory default setting is
2
1
⁄
2
. 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 at right 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.
