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
planters, which has an integrated adjustment lever
for the brush. If you have pre-existing finger meters,
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.
Refer to Figure 7
The adjustable brush provides additional flexibility to
accommodate a wide range of seed sizes. Use lever
to gently rotate the brush into position.
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 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.
