Fertilizer Rate
Fertilizer rate is controlled by:
• Rate adjuster setting
Fertilizer rate is independent of the Drive Type used for
main seed box planting. The fertilizer cups do not have
doors to adjust.
Before setting the rate, raise the drill and rotate the
gauge 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 it is substantially differ-
ent from the material used to generate the charts,
apply a correction factor before selecting the initial
rate from the charts.
2. Consult the fertilizer rate chart for desired
applications density (pounds/acre or kg/hectare).
The chart provides the initial adjuster setting.
3. Configure the adjuster on one or both sides of the
drill.
4. Calibrate the drill for your specific material.
5. Set both rate adjusters identically.
Setting the Fertilizer Adjuster
Refer to Figure 30
Each fertilizer box has its own adjuster, located near box
center. Position the adjuster to the rate from the fertilizer
Chart in the Seed Rate manual.
To adjust:
1. Rotate the adjuster knob located to the right of the
scale . Rotate counter-clockwise to increase rate.
The knob stays at your setting due to springs clamp-
ing a nut at the left end of the shaft.
2. Rotate the adjuster until indicator is about 10 past
the desired value, then move it back to the desired
value.
