Sprocket Indexing (Stagger)

If you are planting:

• with a seed disc having 24 cells or less,

• twin-row crops,

• at seed populations below 45,000 seeds/ac

(111 000 seeds/ha),

you can synchronize each pair of adjacent meters in a

twin row so that you achieve the 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 25.

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

⁄

inch (23.5 cm),

this section of the manual, and the sprocket indexing

charts, do not apply to your operations.

Air-Pro

Meter Stagger Timing Chart

Thumbnail view. Actual charts begin on page 26.

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.
