Sprocket Indexing (Stagger)
Null4:
Null4:
If you are planting:
• with a seed disc having 24 cells or less,
• twin- or tri-row crops,
• at seed populations below:
77 000 seeds/ha (Twin Row), or
116 000 seeds/ha (Triple Row)
you can synchronize the front and rear meters in a twin-
or tri-row so that you achieve the maximum seed-to-seed
spacing between the units of the set.
If the initial indexing does not provide equal spacing, See
“Indexing Fine Adjustment” on page 27.
If you are planting:
- single-row,
- or with seed discs or 25 cells or more,
- or twin/tri-row with seed spacings below 23.5cm,
this section of the manual, and the sprocket indexing
charts, do not apply to your operations.

Meter Stagger Timing Chart
Thumbnail view. Actual charts begin on page 28.
Due to limitations on the number of sprocket teeth and
wheel cell count, it may not be possible to obtain perfect
stagger. Charts and fine adjustment provide the optimal
available stagger.
