Native Grass Meter Shaft Rates
These charts are used during calibration. They provide
rotations of the meter shaft per acre, and are not seed
rate charts. For metric charts, see page 47. Once the pounds per shaft revolution is known for your
seed mix, the charts provide the Transmission, Drive
Type, and Final Sprocket required.
Standard Shaft Rates
Shaft Rates with Seed Rate Reduction
The Native Grass attachment includes, as standard
equipment, an agitator.
Equipment Damage Risk:
Do not transport with seed loaded in the Native Grass box.
Load seed at field. Transport with seed loaded compacts the
seed at the meter inlets and can easily clog agitators and
meters. Drive system operation in the field can then damage
the agitator and drive components.
Seed Lubricant
Add graphite seed lubricant after loading seed in the
Native Grass box. For humid planting environments,
double or triple graphite as needed. Use
1 ⁄
3
cup (80 mL)
across the top of the seed mix. Graphite part numbers:
When drilling, check the amount of seed you are using
by noting the acres drilled, amount of seed added to drill,
and the level of seed in the box. If you suspect you are
drilling more or less seed than desired, and you have
accurately calibrated the drill to your seed, change your
sprocket arrangement to compensate for your field
conditions.
