1.
Raise drill (page 33). Contact drive tires cannot be
turned by hand with drill lowered.
2. Fold wings (page 37) for more convenient access to
cranking location.
3. For clean-out, set both meters 80 or higher (LOW
range), or 10 or higher (HIGH RANGE).
For calibration, set the meter under test per the
instructions in the Seed Rate Manual, and remove a
DRIVER or DRIVEN final gear on the other meter.
4. Open calibration door on meter(s) being cleaned-out
or tested.
5. For calibration, record weight of calibration bag.
Hook bag to meter under test.
6. Move crank handle from storage stob to shaft of left
or right outside contact drive wheel.
7. Turn the hand crank to simulate meter operation dur-
ing planting.
8. Return crank to storage stob at task completion.
Specific recommendations may be made in applicable
manual sections. See:
see “Meter Calibration” in the Seed Rate manual,
see “Unloading Materials” on page 65, and
see “Storage” on page 70.
In general, you may operate the crank as fast as is com-
fortable. For reference, at a field speed of 10 kph
(6.2 mph), the jackshaft rotates at 120 rpm (2 turns per
second).
For clean-out, make sure the variable rate gearboxes are
set:
• above “10” if the final drive range gears are in High
Range mode, or
• above “80” if the final drive range gears are in Low
Range mode.
To change variable rate gearbox and final drive range
gearing see “Setting Material Rates” on page 72.
