10. Weight metered seed. Subtract initial weight of con-
tainer. Divide by three.
11. Multiply by the number of openers on the drill to
determine total pounds seeded per acre. If this figure
is different than desired, change your sprockets and
drive type accordingly.
Note: If your results vary greatly from seed rate chart,
apply the revised Drive Type and Seed Rate
Handle settings, and repeat the calibration pro-
cedure.
12. Set the other wing to match the wing now calibrated.
13. Re-attach the seed tubes on the tested rows. Return
the calibration crank to the storage stob of the wing
customarily used for calibration.
Note: When drilling, check the amount of seed you are
using by noting acres drilled, amount of seed add-
ed to drill, and level of seed in drill box. If you sus-
pect that you are drilling more or less than desired,
and you have accurately calibrated the drill to your
seed, you may need to adjust the seeding rate
slightly to compensate for your field conditions.
