Refer to Figure 4,
which depicts the seed cup door handle in position
At each seed box seed tube, adjust the seed cup door
handle
for the seed size.
The handle has three normal operating position detents:
Note: Handle position
is used for clean-out, not plant-
ing. If set to this position with seed loaded, it may be
difficult to reset it to a normal operating position.
Main Seed Row Shutoff
If alternate row spacings are desired, the unused rows
can be shut off with optional plugs (see Operator Man-
ual).
1.
Clean-out seed. The seed box must be empty prior
to inserting plugs. See “Main Box Clean-Out” in
Operator Manual.
2.
Insert one plug at each row to shut off. Verify the
seed hose path before inserting the plug, as some
hoses do not make a strictly vertical drop to their row
units.
3.
Review seed rate settings prior to planting. Perform
calibration calculations at actual active row count.
