Setting Dry Fertilizer Rate
There are three steps to obtaining the target fertilizer
kilograms per hectare (or pounds per acre):
1. Set Final Drive Range on fertilizer meter (below)
2. Set Variable Rate Gearbox (page 24)
3. Calibrate (page 25).
Seed Meter Final Drive Range
Refer to Figure 9
The meter flute shaft is driven by the agitator shaft
through a pair of interchangeable gears , . The
positioning of these gears creates two final drive ranges.
The rate chart has two page columns, each based on a
specific Final Drive Range. The Ranges are:
• “High” range, which is used for higher fertilizer rates
• “Low” range, which is used for lower fertilizer rates
The two meter shafts are labeled “DRIVING” and
“DRIVEN”.
The “DRIVING” shaft is the upper shaft.
The “DRIVEN” shaft is the lower shaft.
Refer to the Fertilizer Rate chart (page 63), the table at
right, and Figure 9 for setting the meter final drive range.
1. Remove the lynch pins from the ends of both shafts.
2. Remove and position the gears as shown in the table
above.
3. Secure with lynch pins.
