Finger Meter Adjustments
The finger pick up meter has an adjustable brush. The
brush has been pre-set to the optimum setting for most
seed sizes.
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
drills, which has an integrated adjustment lever
for the brush. If you have added pre-existing fin-
ger meters after purchase, there is some chance
that you may have previous model meters, ad-
justed by screwdriver rather than lever. If so, rely
on counting detents to determine the setting. Not
all have 9 detents.
Refer to Figure 3
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.
