Finger Meter Brush Adjustment
The finger pick up meter has an adjustable brush.
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.
Refer to Figure 6
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

. 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 in pounds
per 80,000 seed bag. The table below includes seeds
per pound.
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 previous model meters, adjusted by
screwdriver rather than lever. If so, rely on counting
detents to determine the setting. Not all have 9
detents.
