e.
Rotate the drive gauge wheel until one acre has
been tallied on the acremeter. This will be
approximately 283 rotations on a 20' drill. Be
sure to check the three feeder cups to make sure
each cup has plenty of beans coming into it.
f.
Weigh the beans which has been metered. Di-
vide by three. This will give you the ounces/
pounds metered by each feed cup. Multiply by
the number of openers on your drill to arrive at
the total pounds-per-acre your drill would meter
at that setting. If this figure is different than de-
sired, set your feed cup adjustment lever accord-
ingly.
6.
You may want to repeat the calibration procedure if
the results of your calibration vary greatly from the
suggested setting contained in this manual.
REMEMBER: Tire size, tire air pressure, and field condi-
tions also affect seeding rates. Be certain that your rib
implement tires are 11L x 15" for the 20' drill. Also check
the “Tire Inflation Chart” in Section 2, page 6, for prop-
er inflation. When planting, check the amount of beans
you are using by noting acres planted, amount of beans
added to drill, and level of beans in planter box. If you
suspect that you are planting more or less than desired,
and you have accurately calibrated the drill to your
beans, you may need to adjust the seeding rate slightly
to compensate for your field conditions.
NOTE: This drill is equipped with a four-position feed
cup door on each feed cup. The "highest" handle po-
sition is for wheat and other small grain seeds, the
"middle" position is for soybean and other large bean
seeds. Should excessive cracking occur to the large
seeds, drop the handle to the "lowest" position. The
wide open position will allow complete clean out of
the feed cup. MAKE SURE all handles are in the
same position before planting.
NOTE: Do not open the cup to the wide open position
with beans in the box unless complete clean out is
desired.
