Main Seed Box Charts
Seed cup planting rate is determined by:
• Crop and seed variant
• Drive Type sprockets
• Seed Cup sprocket engagement (Seed Rate Handle)
There are no other adjustments.
The rates indicated in the charts are approximate values.
To assure the most accurate seeding rate it is recom-
mended that the drill be calibrated for the desired seed at
the time of planting.
