NOTE: If rear row does not appear centered between front row seeds, small adjustment
may be made to the stagger. Refer to "Adjustments to Seed Stagger on 6 Finger Meters."
NOTE: Indexing finger pickup meters can be done with the drill in planting position or with
the drill raised (all openers in their lowest position).
1. Pick the planting population which you want to plant from the chart above.
NOTE: When indexing sprockets, the top side of the meter drive chain must be tight.
2. Set the front row meter drive sprockets so the tooth stamped #1 is straight up.
3. Set the rear row meter drive sprockets to match the number from the chart above. Be sure
Population Range
Seed Spacing Range
the number is straight up.
