When desired population is known, use the following formula to find transmission sprocket settings for row widths not shown in seed charts.

FORMULA:

(A ÷ B) x C = D

A = Desired row width (centimeters or inches)

B = Row width column in the seed chart (for crop being planted) nearest to desired row width

C = Seed population desired (hectares or acres)

D = Calculated comparison population value

The following example assumes corn will be planted (using vacuum meters with corn-30 cell disks) with planting units set on 71 cm (28 in.) rows and a desired seed population of 69,000 seeds/hectare (28,000 seeds/acre). Using seed chart for corn-30 cells, the

EXAMPLES:

• (71 cm ÷ 76 cm) x 69,000 seed/ha = 64,460 seeds/ha

  Find population value in Metric chart nearest to calculated comparison population value (65,203 seeds/hectare).

  Use the sprocket combinations in the corresponding rows (29-tooth driver and 27-tooth driven) to achieve desired population (69,000 seeds/hectare).

• (28 in. ÷ 30 in. ) x 28,000 seeds/acre = 26,133 seeds/acre

  Find population value in Standard chart nearest to calculated comparison population value (26,318 seeds/acre).

  Use the sprocket combinations in the corresponding rows (29-tooth driver and 27-tooth driven) to achieve desired population (28,000 seeds/acre).
