12-Finger Meter Stagger Adjustment
Before making any Indexing Adjustments, check actual
planted seed spacing. Seed Spacing is found by mea-
suring the distance between 25 correctly planted seeds
in one row and dividing by 24. (A visible skip or double
should be counted as one seed.) Make sure current
rear sprocket index number matches the number in the
indexing chart for actual seed spacing being planted.
Find your current indexing value row in the charts.
Each (sprocket tooth) number directly above or below
the current rear meter sprocket setting in the right most
column of the seed indexing chart represents a small
movement of the rear row seed relative to the front row
seed.
Changing rear your sprocket to the next number down
in the chart retards, moving each rear row seed back a
small amount.
Changing rear sprocket to the next number up in the
chart advances, moving each rear row seed ahead a
small amount.
Example 1: The 12 Finger (Twin Row 30in) planting
population is 34800 or 12in seed spacing. The chart
setting for the rear sprocket is (3). Each rear row seed
should fall 6in behind the front row seed.
If each rear row seed measures 7in behind the front
row seed, reset the rear meter sprocket to the next
number up in the chart (11). This will move the rear
seeds ahead and make the stagger closer to 6in.
Example 2: The 12 Finger (Twin Row 30in) planting
population is 34800 or 12in seed spacing. The chart
setting for the rear sprocket is (3). Each rear row seed
should fall 6in behind the front row seed.
If each rear row seed measures 5in behind the front
row seed, reset the rear meter sprocket to the next
number down in the chart (14). This will move the rear
seeds back to make the stagger closer to 6in.
