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).

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.
