Position 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 position.
Make sure all handles are in same position before drilling.

Seed-Cup-Door Handle
Check Seeding Rate
1.
Record the weight of an empty container large enough
to hold seed metered for one acre.
2.
Place several pounds of seed over three seed cups on
an outside end of drill box. Pull seed tubes off these
three openers.
3.
Raise drill off ground.

4.
Turn gauge wheel a few turns to fill cups with
seed. Turn wheel until seed drops to ground from
all three cups.
5.
Place a container under the three seed tubes to
gather seed as it is metered.
6.
Turn drive gauge wheel for one acre. Refer to the
chart below for the exact number of tire revolu-
tions to equal one acre. Check that three seed
cups have plenty of seed coming into them.
7.
Weigh metered seed. Subtract initial weight of
empty container. Divide by three for the amount
metered by each seed cup, then multiply by the
number of drill openers for the pounds-per-acre
seeding rate. If this figure is different than desired,
adjust the seed-rate handle and recheck the rate.
NOTE: If your results vary greatly from the charts, you
may want to repeat the calibration procedure.
8.
When drilling, note acres drilled, amount of seed
added and level of seed in drill box. If you are
seeding more or less than desired, adjust seeding
rate slightly to compensate for your field condi-
tions.
