Seed Rate
Rates are set separately for seed, fertilizer (page 17) and
treatments (Option, page 26).
Seed rate is determined by:
1. consulting the seed rate charts,
2. installing the correct meter (in the case of finger
meters, the appropriate finger sets, inserts and
brushes, and in the case of the brush meter, the
appropriate seed plates),
3. setting the Range and Transmission driving/driven
sprocket combinations on each wing, and
4. checking the rate.
There are separate charts for brush and finger pickup
meters. If you are unfamiliar with the charts, see
“Reading a Brush Meter Chart” below or “Reading a
Brush Meter Chart” on page 4.
To change meters, see “Exchanging Meters” in the
Operator manual.
About Finger Meter Charts
The charts are for meters with 12-fingers, and apply to
both Corn and Sunflower configurations.
Some sizes of sunflower seeds meter more reliably with
the corn finger set, insert and brush. See the table below.
See the Operator manual (401-832M) for meter
reconfiguration instructions.
