36in Twin Row Sprocket Indexing
These are NOT seed rate or seed spacing charts. These are
charts for staggering seed spacing between the rows of a twin
row.
Note: For adjusting spacing between rows of the pair,
see “Indexing Fine Adjustment” on page 51.
Verify the 12:00 sprocket tooth position with the top length of
chain taut.
