You may want to repeat the calibration procedure if
the results of your calibration vary greatly from what
is listed on the seed rate chart.
IMPORTANT: Tire size and field conditions will also af-
fect seeding rates. Be certain that your drill rib tires are
9.00 x 24 and that they have the proper inflation. When
drilling, check the amount of seed you are using by not-
ing acres drilled, amount of seed added to drill, and level
of seed in drill box. If you suspect that you are drilling
more or less than desired, and you have accurately cal-
ibrated the drill to your seed, you may need to adjust the
seeding rate slightly to compensate for your field condi-
tions.
NOTE: Pounds per acre listed below are total
pounds of bulk seed {live and inert material}.
