Sprocket Indexing (Stagger)
If you are planting:
• with a seed disc having 24 cells or less,
• twin-row crops,
• at seed populations below 161 000 seeds/ha
(60,000 seeds/acre)
you can synchronize each pair of adjacent meters in a
twin row for maximum seed-to-seed spacing between the
units of the pair.
If the initial indexing does not provide equal spacing, see
“Indexing Fine Adjustment” on page 69.
If you are planting:
- single-row, or
- with seed discs or 25 cells or more, or
- a volumetric crop, or
- twin row with seed spacings below 23.5 cm (9
1
⁄
4
inch),
this section of the manual, and the sprocket indexing
charts, do not apply to your operations.

Meter Stagger Timing Chart (metric)
Thumbnail view. Actual charts begin on page 70.
Crushing Hazard:
Install transport locks. Do not rely on hydraulics to hold the
planter at raised. This adjustment takes some time.
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.
