Checking Seeding Rate
!
WARNING!
You may be severely injured or killed by being crushed by the
falling implement. Always have transport locks in place and
frame sufficiently blocked up when working on the implement.
1. Raise drill with tractor hydraulics so gauge wheels are
off ground. Rotate drive (far right) gauge wheel to see
that metering system is working properly and free
from foreign material.
2. Check that implement tires are 13.0/55-16 12 PR AW
and properly inflated. Refer to Tire Inflation Chart,
“Appendix,” page 40.
3. Record weight of an empty container large enough to
hold seed metered for one hectare (acre).
4. Place several kilos (pounds) of seed over three seed
cups on an outside end of the seed box. Pull seed
tubes off of these three openers.
5. Turn crank on contact-wheel shaft on right-hand side
of drill several times to fill seed cups. Turn crank until
seed drops to ground from each seed cup.
6. Place a container under these three tubes to gather
metered seed.
7. Turn crank on contact-wheel shaft clockwise 32 revo-
lutions for 1/100 hectare seeding rate (13 rotations for
a 1/100 acre seeding rate). While turning, check that
the seed cups have plenty of seed coming into them.
NOTE: If implement is not equipped with a calibration
crank, turn drive gauge wheel 319 rotations for a one-hec-
tare seeding rate or 127 rotation for a one-acre seeding
rate.
8. Weigh metered seed. Subtract initial container weight.
Multiply weight by
• 633.33 for 158 mm (6.2 inch) row spacing or
to determine total kilograms per hectare (pounds per
acre) seeded. If this figure is different than desired,
adjust seed-rate handle accordingly.
NOTE: You may want to repeat the calibration procedure if
your results vary greatly from the seed-rate chart.
9. When drilling, check seeding rate by noting acres
drilled, amount of seed added to drill and seed level in
seed box. If you are seeding more or less than de-
sired, adjust rate slightly to compensate for field con-
ditions.
