Native Grass Attachment Series II
The Native Grass box is for seeding fluffy, native grass
blends like Big Blue Stem, Indian Grass, and Oats
Grama.
Setting Native Grass Rate
Refer to Figure 6 and Figure 7
Seeding rate of the native Grass box is controlled by
the gearbox Drive Type
and a Driven sprocket on
the gearbox output chain. Rate levers on other boxes
do not affect Native Grass rate.
Setting rate for Native Grass mixes (other than Brome)
rate requires calibration, which is done using any cur-
rent Drive Type and Driven sprocket combination. The
results of the calibration determine the actual Drive
Type and Driven sprocket to use. The process is:
• Meter a sample using the calibration crank.
• Weigh the sample and use that value in the calibra-
tion formulas.
• Find the final drive setup in the chart.
A step-by-step table and example follow the detailed
Native Grass Mix instructions on page 20.
Instructions and chart for Brome are on page 24.
