Brush meter adjustments begins on page 60.
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.
Refer to Figure 61
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. 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 in pounds
per 80 000 seed bag. The table below includes seeds
per pound and seeds per kilogram.

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.
