Setting 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.
1. Loosen wing nut under handle.
2. Set indicator to about 10 past value from Seed
Rate Chart, then move handle back to target value.
3. Tighten wing nut.
