9. Turn gauge wheel or calibration crank for:
595 rotations for the 706 drill and
411 rotations for the 1006 drill.
This is equal to one acre.
10. Check that the three feed cups have plenty of fer-
tilizer coming into them.
11. Weigh metered material. Subtract initial weight of
the empty container. Divide by 3. Multiply by the
number of openers on your drill to determine total
pounds-per-acre metered. If this figure is different
than desired, reset adjustment knob accordingly.

Rates in Pounds per Acre
Density Conversion Charts
The fertilizer meter rate charts are based on fertilizer
with a density of 65 pounds per cubic foot (1.04 kilo-
grams per liter). If you are applying fertilizer of a differ-
ent density, use the following table to convert
application rate.
Example: Your fertilizer has a density of 75 pounds per
cubic foot, and you want to apply 100 pounds per acre.
Multiply the desired application rate by the conversion
factor.
100 x 0.87 = 87
Adjust drill to the setting closest to 87 pounds per acre.
