Main Box Seed Rate Handle
There are identical seed rate handles for each half of the
drill. Generally, both need to be set identically. You can
stop seed flow to one half of the drill by setting a handle
to zero (for point-row planting, for example).
The seed rate handle controls the percent engagement
of the seed sprocket in each seed cup.
Refer to Figure 3

Seed Cup Door
Refer to Figure 4,
which depicts the seed cup door handle in position

The handle has three normal operating position detents:
Note: Handle position is used for cleanout, not plant-
ing. If set to this position with seed loaded, it may be
difficult to reset it to a normal operating position.
