Setting Planting Rate
There are four 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 charts:
• Main Seed Box, page 6.
• Small Seeds Box, page 13.
• Native Grass Seeds Box, page 15 (Native Grass
mixes other than Brome require calibration).
3. Set the rate for the seed box in use:
• Main Seed Box, page 2.
• Small Seeds Box, page 10.
• Native Grass Seeds Box, page 15.
4. Check planting rate:
• Main Seed Box, page 5.
• Small Seeds Box, page 12.
• Native Grass Seeds Box, page 15.
The charts are based on original factory tires, and
cleaned, untreated seed of average size and test weight.
Many factors affect field results, including field condi-
tions, foreign material, seed size, seed treatment and tire
pressure. Minor adjustments are likely to be needed.
