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 seed jackshaft sprocket. See page 3.
In our example, this is Drive Type 2 (34T sprocket).
3. Find your row spacing in the far left column.
4. Locate your desired seed rate in the table row for
your row spacing.
In our example, 49 is the closest to 48.
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 4.
In our example, we will start with a handle setting
of 40, and calibrate. 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.
