Meter Rate Adjustment
Seed rate is determined by:
• Flute shafts (covered on page 65):
standard 2-star/1x rate, or
optional 3-star/1.5x or 4-star/2x rates
• Single/twin hopper metering (covered on page 66).
• Seed meter Final Drive Range gearing
• Variable Rate Gearbox setting
The Seed Rate Manual charts are based on cleaned
untreated seed of average size and test weight. Many
factors affect meter rates including foreign material, seed
treatment, seed size, field conditions, and test weight.
Minor adjustments will be needed to compensate for
these factors. Initially set the rates according to the
charts, then calibrate for your material and conditions.
Calibration is also required to set up the monitor Calibra-
tion Constant. With the correct Calibration Constant and
material density the monitor can be used to help fine
tune the variable rate gearbox setting.
Seed Meter Final Drive Range
Refer to Figure 60
The meter flute shaft is driven by the agitator shaft
through a pair of interchangeable gears , . The posi-
tioning of these gears creates two final drive ranges.
Each seed 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 meter shafts are DRIVING” and “DRIVEN”.
The “DRIVING” shaft is the upper (agitator) shaft.
The “DRIVEN” shaft is the lower (flute) shaft.
Refer to the Seed Rate chart (or Fertilizer Rate chart),
the table at right, and Figure 60 for setting the seed
meter final drive range.
1. Remove the nut and bolt ( , not visible) securing the
application rate sensor to the restraining straps at
the meter sensor mount.
2. Loosen the thumbscrew .
3. Remove the pins from both shafts. Move the rpm
sensor clear of the flute shaft.
4. Remove and position the gears as shown in the table
at right.
5. Secure the DRIVING gear on the agitator shaft with
a pin.
6. Secure the DRIVEN gear with the rpm sensor and a
pin.
7. Use the thumbscrew to eliminate any rotational play
in the sensor-to-shaft coupling.
8. Using the nut and bolt, secure the rpm sensor to the
restraining straps at the meter sensor mount.

Disable a Seed Meter
To avoid operating a meter:
1. Remove a final range gear and leave it off.
2. Set the variable rate gearbox to zero.
These steps are recommended even when the unused
hopper is empty, to:
• reduce gearbox and meter wear
• during calibration, to avoid clogging air tubes at the
meter not under test, and;
• avoid metering undesired material in the field.
