Main Box Seed Rate Handle
There are main box seed rate handles for each section of
the drill (2 or 3 handles total). Generally, all need to be
set identically, and you need to calibrate only one
section.
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 seed flow to a drill section
by setting a handle to zero.
To set a handle:
1. Loosen wing nut under handle.
2. Set indicator to just past value from Seed Rate
Chart.
3. Tighten wing nut.
Position Seed Cup Doors
Refer to Figure 4,
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 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 the
Operator manual.
Refer to Figure 5
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.

(middle detent) is for larger seeds.
Use it for soybeans and similar larger seeds.
