Main Box Seed Rate Handle
Refer to Figure 30
There are main box seed rate handles for each section of
the drill (2 handles total). Generally, they 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.
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. Move indicator from current setting to about 10
past the new desired value from calibration or the
Seed Rate Chart, then move it back to the new
desired value.
3. Tighten wing nut.
Position Seed Cup Doors
Refer to Figure 31
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 cleanout, not
planting. If set to this position with seed loaded, it
may be difficult to reset it to a normal operating
position.
