12-Finger Meter Stagger Adjustment
Before making any Indexing Adjustments, check actual
planted seed spacing. Seed Spacing is found by measur-
ing 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 index-
ing 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 col-
umn of the seed indexing chart represents a small move-
ment 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 pop-
ulation 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 pop-
ulation 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.
