5. Turn gauge wheel or crank several times to fill
seed cups with seed. Turn wheel or calibration
crank until seed falls to the ground from each cup.
6. Place empty container under the three seed tubes
to gather seed as it is metered.
7. Rotate gauge wheel or calibration crank
595 rotations for 706NT and
411 rotations for 1006NT.
This is equal to one acre.
Note: You can also rotate the gauge wheel jackshaft by
means of a wrench or socket. If rotating gauge
wheel jackshaft, disengage the lockout on the
drive wheel and use same number of rotations as
for rotating drive wheel.
8. Check that the three seed cups have plenty of
seed coming into them.
9. Weigh metered seed. Subtract initial weight of
container. Divide by three. Multiply by the number
of openers on your drill to determine total pounds
seeded per acre. If this figure is different than
desired, change your sprockets and drive type
accordingly.
Note: You may want to repeat the calibration procedure
if your results vary greatly from seed rate chart.
10. 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 you seed, you may need to change your
sprocket arrangement to compensate for your field
conditions.
The Native Grass Rate Chart is based on a seed mix
of 5.7 pounds of pure live seed per 11.1 pounds of
bulk. The pure live seed mix:
• Big Blue - 1.5 pounds
• Little Blue - 0.8 pounds
• Slide Oats Grama - 0 6 pounds
• Western Wheat Grass - 1 pound
• Switch Grass - 0.3 pounds
• Indian Grass - 1.5 pounds
Factors which will affect seeding rates are: weight of
seed, size of seed, relative humidity and moisture con-
tent of the seed, ratio of inert material to seed, different
proportions of seed types affecting density, tire config-
uration, tire pressure and tire slippage.
All seed mixes will vary.
The rates are based on 9.00 x 24 8 Ply tires.

IMPORTANT !
The attached charts are to be used as a reference to
your own native grass mix. All native grass mixes
will vary so this is why you must calibrate each mix
using our charts as a starting point only.
IMPORTANT !
To prevent damage to the Native Grass box agitator
and its drive components, do not transport drill with
Native Grass box loaded with seed.
IMPORTANT !
For Native Grass Mix Only Powdered graphite must
be mixed with the native grass seed mix for proper
seed flow and metering.
Recommended Usage:
Sprinkle 1/3 cup of graphite per 6 ft of seed box on
top of the native grass seed mix.
For humid planting environments, double or triple
rate as needed.
