2. Adjust Seed-Rate Handle
Refer to Figure 22
Position the handle to the setting indicated on the seed-
rate chart. To adjust, loosen the wing nut under the
handle and slide until indicator lines up with desired
setting. Tighten nut.
3. Set Seed-Cup Doors
Refer to Figure 23
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. For
seed-cup clean out, move the handles to the fourth,
wide-open position. Make sure all handles are in
the same position before drilling.
4. Check Seeding Rate
a. Place several pounds of seed over the three
seed cups on the outside end of the drill box.
b. Disconnect the seed tubes from the three
openers fed by the covered cups.
c. Raise the drill off the ground.
d. Record the empty weight of a container large
enough to hold the seed metered for one acre.
e. Turn gauge wheels until seed drops to the
ground from each cup.
f. Place a container under the three seed tubes to
gather the seed as it is metered.
g. Rotate the gauge wheel until one acre has
been tallied on the acremeter. This will be
about 225 rotations on a 24-foot drill and about
181 rotations on a 30-foot drill. Check that the
seed cups have plenty of seed coming into
them.
h. Weigh the metered seed. Subtract the initial
weight of the container. Divide by three.
Multiply by the number of openers on your drill
for the pounds-per-acre seeding rate. If this
figure is different than desired, re-adjust the
seed-rate handle and recheck the rate.
5. When satisfied with the seeding rate, repeat steps 1
through 3 for the other drill box, setting it to the same
rate.
