Set Seed-Rate Handle
The position the handle (shown in Figure 3-8) to the set-
ting indicated on the chart. To adjust, loosen the wing nut
under the handle. Slide handle until the indicator lines up
with the correct setting.

Seed-Rate Handle
Position Seed-Cup Doors
Refer to Figure 3-9. For wheat and other small seeds,
move the seed-cup-door handles to the highest position.
For soybeans and other large seeds, lower the handles to
the second position. If excessive seed cracking occurs,
lower the handles to the third position. Move the handles
to the fourth, wide-open position for seed-cup clean out.
Make sure all handles are in same position before drilling.

Check Seeding Rate
1.
Hydraulically lower drill to planting position to activate
clutch.
5. Check that tires are 9.0 x 24 rib implement and prop-
erly inflated. Refer to "Tire Inflation Chart," page 35.
6. Jack drive (left) end wheel off ground. Rotate wheel to
see that drive system is working properly and seed
cups are free from foreign material.
7. Record weight of an empty container large enough to
hold seed metered for one acre.
8. Place several pounds of seed over three seed cups on
an outside end of the drill box. Pull the seed tubes off
of these three openers.
9. Turn drive end wheel several times to fill seed-cups
with seed. Turn wheel until seed falls to the ground
from each cup.
10. Place container under the three tubes to gather
metered seed.
11. Rotate drive wheel until 1 acre is tallied on acremeter.
This will be 592 rotations on a 7-foot drill or 422 rota-
tions on a 10-foot drill. You can also rotate the gauge
wheel jackshaft by means of a wrench or socket. If
rotating gauge wheel jackshaft, disengage the lockout
on the drive wheel and use same number of rotations
as for rotating drive wheel. Check that the three seed
cups have plenty of seed coming into them.
12. Weigh metered seed. Subtract initial weight of con-
tainer. Divide by three. Multiply by the number of
openers on your drill to determine total pounds
seeded per acre. If this figure is different than desired,
reset sprockets accordingly.
NOTE: You may want to repeat the calibration procedure
if your results vary greatly from the seed-rate chart.
13. When drilling, check seeding rate by noting acres
drilled, amount of seed added to drill and seed level in
drill box. If you are seeding more or less than desired,
adjust seeding rate slightly to compensate for field
conditions.
