Setting Seed-Rate Handle
There is a seed-rate-adjustment handle for each drill sec-
tion. See Figure 3-3. Position handles to the setting indi-
cated on the seed-rate charts. To adjust handle, loosen
wing nut under handle and slide handle until indicator lines
up with correct setting.

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

Checking Seeding Rate
You may be severely injured or killed by being crushed from a
falling implement or openers. Always have transport locks in
place and frame sufficiently blocked up when working on the
drill.
1. Jack up drive gauge wheel(s) and rotate them to see
that seed cups and drives are working properly and
free from foreign material.
2. Check that your gauge-wheel tires are 9.5L - 15, 6-ply
rib implement and properly inflated. Refer to Tire Infla-
tion Chart, “Appendix,” page 60.
3. Record weight of an empty container large enough to
hold seed metered for one acre.
4. Place several pounds of seed over three seed cups on
an outside end of drill box. Pull seed tubes off of
these three openers.
5. Turn drive wheel several times to fill seed cups. Turn
wheel until seed drops to ground from each seed cup.
6. Place empty container under three tubes to gather
metered seed.
7. Turn drive wheel until one acre is tallied on acremeter
(203 wheel rotations). While turning, check that cups
have plenty of seed coming into them.
8. Weigh metered seed. Subtract initial weight of con-
tainer. Divide by three. Multiply by number of openers
on your drill to determine total pounds-per-acre seed-
ed. If this figure is different than desired, reset sprock-
ets accordingly.
NOTE: You may want to repeat calibration procedure if
your results vary greatly from seed-rate chart.
9. 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 rate slightly to compensate for field conditions.
