Seed Rate Charts
Seed rate charts begin on page 96. The charts give
transmission sprocket combinations and drive range
sprocket combinations for each row spacing, to achieve
the population or pounds per acre desired. The charts
also give seed spacing for singulated seed and
maximum planting speed for both singulated and
volumetric seeds.
Each seed chart has a corresponding page showing the
different drive ranges for that seed and a transmission
sprocket reference.
 NOTE: Use 1/200 acre for populations less than
100,000 seeds/acre. Use 1/1,000 acre for
populations above 100,000 seeds/acre.
