Reading a Seed Rate Chart
1. Find your seed. Charts are in alphabetical order by
seed name. Charts covering more than one seed
may be out of order.
For Sudan, see Flax.
There are multiple charts for some seeds, and the
rates may overlap. Use the chart where your desired
rate is closest to 50 on the Seed Rate Handle scale.
If your seed is not listed, find one with similar size,
shape and density. Density of the test seed used to
develop the chart appears under the right end of the
handle scale values.
2. Note the Drive Type in the upper left corner of the
chart for your seed. This number (1-4) is used to
determine the gearbox handle setting. See page 2.
3. Find your row spacing in the far left column.
4. Locate your desired seed rate in the table row for
your row spacing.
5. Note the Seed Rate Handle setting required, at the
top of the column at that seed rate. This is the initial
value set on the Seed Rate Handle. See page 3.
When a target rate falls halfway between handle
settings, you can adjust the handle slightly to
compensate, but calibration is apt to result in further
adjustment anyway.
