Finger Meter Planting
The basic seed rate for finger meters is determined by
the meter finger count (6 or 12), and the drive setup.
Finger meters have an additional adjustment for optimum
results:
• Meter brush (see page 32)
• Sprocket Indexing for twin-row (see page 48)
Recommended speed is 4
1
⁄
2
to 5 miles per hour.
Excess speeds are known to deteriorate seed spacing
control and depth control.
Reading a Finger Meter Rate Chart
Hydraulic or Ground Drive
1.
Consult the chart for your:
row spacing and
meter type (finger count).
2.
Find the desired seed population or seed spacing.
3.
Note the range of meter rpms suitable for that popu-
lation. These rpm ranges govern the suitable plant-
ing speeds.
The shaded rpms are the recommended rpms for most consis-
tent results with flat kernel corn.
For round kernel corn, use either shaded or un-shaded values.
Blank table cells represent rates/speeds that are not recom-
mended regardless of seed type.
