Setting Planting Rate
There are six steps to obtaining the desired number of
seeds per acre:
1. Know the characteristics of the seed.
Consult your seed supplier’s reference documents.
2. Find your settings in the Seed Cup rate charts start-
ing on on page 4.
3. Set the Drive Type.
See “Setting Drive Type” on page 2.
4. Set the Seed Rate Handle.
See “Set Seed Rate Handle” on page 3.
5. Adjust Seed Cup doors for the seed.
See “Position Seed Cup Doors” on page 3.
6. Check planting rate.
See “Checking Seed Cup Rate” on page 10.
The charts are based on original factory tires, and
cleaned, untreated seed of average size and test
weight. Many factors will affect field results, including
field conditions, foreign material, seed size, seed treat-
ment and tire pressure.
Minor adjustments are likely to be needed.
