Reading a Volumetric Chart
1.
Using the rate range charts on pages 30-35, find the
chart for your seed, in this example, Hard Red
Winter Wheat.
2.
Find your row spacing at right side of the chart,
15 inch single row in this example.
3.
The speed and rate ranges are determined by
allowable meter rpms. Enter the Meter RPM limits in
the seed monitor to set alarms for operations that are
too slow or too fast.
4.
With your desired seed population in mind (for
example, 75 pounds/ac), note at which field speeds
that population remains in range. These are the
ranges, in pounds per acre, within which the seed is
metered accurately. In this example, speeds of
4 to 6 mph are in range for the “WHEAT NARROW”
wheel, but only 8 mph is in range for the
“WHEAT WIDE” wheel. Assuming that a slower
speed is desired, choose the “NARROW” wheel.
5.
Verify that you have the correct seed wheel for the
chart, WHEAT NARROW in this example.
6.
For Rice, note that a Flow Gate (p/n 817-529C) is
required inside each seed meter. Rice seed wheels
may be ordered:
as wheels only: (“D” p/n, without Flow Gate), or
as kits (“A” p/n, with Flow Gate).
7.
The tables on pages 30-35 and page 36 are
insufficient for setting the seed monitor to control the
hydraulic drive. The monitor also needs a figure for
meter throughput. Running a calibration (page 27) is
the easiest way to ensure that your material is
accurately applied.
Population Risk:
If your desired seed rate and planting speed fall within the
chart range, proceed to calibration and planting. Otherwise,
you must pick another combination of seed wheel and planting
speed.

Calibrate. Planting volumetric (“granular”) seed based only
on chart data is risky. Your material can vary substantially
from the test material used to generate the charts.
