Meter Adjustments
There are adjustments for seed inlet, and choice of disks.
There are no other adjustments, in particular no brush
adjustments, at the meter.
Meter Rain Cover
The rain cover keeps side winds from unseating seed in
disk pockets. It also keeps precipitation, sunlight and
field debris out of the meters.
Refer to Figure 86
To remove the rain cover, peel the flexible snap latches,
at top
and rear , away from the meter housing. Pivot
the cover forward and down at tab in slot.
When removing a cover, inspect it for damage and
missing parts. If a cover does not have both latches, and
an intact edge seal under the latches, the cover is apt to
be lost during transport or field operations.
To replace a latch, temporarily remove the seal near the
latch. Slide the replacement latch onto the cover lugs
from the meter side, then snap the other end down over
the lugs. Re-install the seal.
Seed Inlet Shutter Adjustment
Refer to Figure 87 (showing the shutter at setting 3)
The seed inlet shutter regulates the volume of bulk seed
presented to the seed disk. The operating settings vary
with crop, seed size and treatments. The shutter also has
settings for row shut-off (completely closed), and
clean-out (wide open).
The Seed Rate Charts include suggested initial shutter
settings. Refine these settings based on experience, and
on inspection of the slope of the seed pool at the bottom
of the seed disk.
The shutter is operated by a handle. Lift the handle away
from the meter plate. Move the handle to half a setting
higher than the new setting, then back to the new setting,
and lower the pawl into that slot.
The table at right is a general summary of shutter
settings.
