Setting Fertilizer Rate
Fertilizer rate is controlled by:
• Range sprockets for coarse rate
• Driver/Driven sprockets for general control of rate
• Rate adjuster for fine control of rate
Fertilizer rate is independent of main seed box Drive
Type and independent of Small Seeds. The fertilizer cups
do not have doors to adjust other than the gates con-
trolled by the adjuster knob.
Before setting the rate, raise the drill and rotate the con-
tact wheels. Check that meters, tubes and drives are
working properly and are free from foreign material.
The procedure for setting the fertilizer rate is:
1. Know your material density. If substantially different
from the chart reference material, apply a correction
factor before selecting the initial rate from the charts.
2. Consult the fertilizer rate chart for desired applica-
tions density (kg/hectare or pounds/acre). The chart
provides the initial range and driver/driven settings.
Note: Chart rates are at adjuster setting 100.
3. If a chart rate is not sufficiently close to the desired
rate, choose a higher rate, and reduce it with an
adjuster setting. A chart provides a rough correspon-
dence between knob setting and percent of maxi-
mum rate.
Note: Calibration is always recommended, but if an ad-
juster setting of less than 100 is needed, calibration
is essential.
4. Calibrate the drill for your specific material.
