Fertilizer Box Operation
The 3S-3000F is equipped with a fertilizer compartment
so you can plant seed and apply fertilizer in the same field
pass. Use dry, granular fertilizer and follow the procedure
below.
1. Clean any seed or debris from the fertilizer compart-
ment.
2. Adjust the seed and fertilizer compartments to desired
capacity. The 3S-3000F is equipped with standard di-
viders that partition the drill boxes into 60 percent
seed and 40 percent fertilizer. If your drill is outfitted
with optional offset dividers, the seed-to-fertilizer ratio
can be changed. Refer to Seed and Fertilizer Capaci-
ty, “Adjustments,” on page 48.
3. Calibrate the fertilizer application rate as explained
under Fertilizer Rate Adjustment and Fertilizer Rate
Calibration, “Adjustments,” on page 38.
4. Check that the divider door is closed so seed and fer-
tilizer cannot pass between compartments. See Fig-
ure 2-13.
5. Check that the fertilizer cleanout door is latched se-
curely as shown in Figure 2-11. Close all door latches
before loading the fertilizer compartment.

6. Open the lid over the fertilizer compartment and swivel
back until it rests against the open drill box lid. See
Figure 2-12. The fertilizer lid serves as a spill guard to
keep fertilizer out of the seed compartment.
