Setting Fertilizer Rate
The 3S-4000HDF fertilizer meters are driven from the
clutch shaft through a series of sprockets. This system is
independent of the seed meter drive, and is unaffected
by Drive Type. Fertilizer rate is adjusted by changing
1 to 3 sprockets on each drill section (3 sets total).
Fertilizer application rates vary with fertilizer type,
density and particle size. Relative humidity and field
conditions can also affect application rates. The chart on
page 19 is based on fertilizer with average particle size
and a density of 65 pounds per cubic foot. Initially set
rate according to charts, then calibrate the drill to your
material as described on this page.
Perform setup and calibration for the left drill box. Once
determined, set the center and right boxes to match.
Accurately obtaining your application rate requires four
steps:
1. Adjusting target rate for large differences between
material and chart density.
2. Setting Range sprocket (from chart)
3. Setting initial Driver / Driven sprockets (from chart)
4. Calibration: checking actual application rate
Adjusting for Density
The fertilizer chart is based on fertilizer with a density of
65 pounds per cubic foot (1.04 kg/liter). If your fertilizer
density is within a few percent of that, skip this step and
rely on calibration to determine final Driver/Driven setup.
For larger variances, particularly with very low densities,
pre-compensating can simplify calibration, by choosing a
different target chart value for the application rate.
1. Find your actual material density. Normally, this
reported on the container in which it was supplied. If
not, weigh a known volume and calculate it.
2. Find your material Density in the table at right, and
the Conversion Factor below it.
3. Adjust your target application rate prior to consulting
the Fertilizer Rate Chart.
4. Consult the Fertilizer Rate Chart for the Adjusted
rate.
5. Calibrate using the sprocket setup for the adjusted
rate.

Example: Your fertilizer has a density of 45 pounds per
cubic foot, and you want to apply 100 pounds per acre
with your 7.5in drill.
Example: the adjusted 145 rate corresponds to a High
Range, and 17T/19T Driver/Driven final drive.
