Main and Dual Box Seed Rate Handle
Refer to Figure 7
There is a single rate handle for the entire box. There are
separate handles for the standard main seed box and the
optional dual seed box.
The seed rate handle controls the percent engagement
of the seed sprocket in each seed cup. The initial setting
of the handle is given by the Seed Rate Chart.
Note: You can temporarily stop main seed flow (such as
for adjusting level/depth) with handle set to zero.
To set the handle:
1. Loosen wing nut under handle.
2. Move indicator from current setting to about 10
higher than the new desired value from calibration or
the Seed Rate Chart, then back to the desired value.
3. Tighten wing nut.
Position Seed Cup Doors
Refer to Figure 8,
which depicts the seed cup door handle in position
.
At each main 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
planting. If set to this position with seed loaded,
it may be difficult to reset it to a normal operating
position.
Main/Dual Seed Row Shutoff
If alternate row spacings are desired, the unused rows
can be shut off with optional plugs.
1. Clean-out seed. The seed box must be empty prior
to inserting plugs. See “Main Box Clean-Out” in
Operator Manual.
Refer to Figure 9
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 with the actual active row
count.
