Seed Meter Final Drive Range
Refer to Figure 4 and Figure 5 (which depict meters without
guards - if your cart included guards, do not operate without
them)
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.
Each rate chart is based on a specific Final Drive Range.
The Ranges are:
• “High” range, which is used for larger seeds and
higher seeding rates
• “Low” range, which is used for smaller seeds and
lower seeding rates
The two seed meter shafts are labelled “DRIVING” and
“DRIVEN”.
The “DRIVING” shaft is the upper shaft.
The “DRIVEN” shaft is the lower shaft.
Refer to the Seed Rate Chart (or Fertilizer Rate Chart),
the table below, and Figure 4 and Figure 5 for setting the
seed 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.
