Main Box Seed Rate Handle
There are main box seed rate handles for each section of
the drill (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
2.
Move indicator
to a rate about 10 higher than the
suggested rate from Seed Rate Chart. Then move
handle back to chart rate.
3.
Tighten wing nut.

ing. If set to this position with seed loaded, it may be
difficult to reset it to a normal operating position.
