Small Seeds Seed Cup Lever Adjustment
Refer to Figure 6
Position the small seeds seed cup lever to setting indi-
cated on Small Seeds Seed Rate Chart on the next
page. To adjust, loosen wing nut
under handle .
Slide handle until indicator lines up with correct set-
ting. Tighten wing nut.
Note: Note: You may need to increase seed cup setting
for lighter than average seed or decrease seed
cup setting for heavier than average seed.
Check Small Seeds Seed Rate
1. Record 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 small seeds box. Pull
drop tube of these seed cups from their hose
mounts.
3. To calibrate, raise gauge wheel off the ground or
use the calibration crank handle.
4. Rotate gauge wheel or crank to see that feed cups
and drive are working properly and are free from
foreign matter.
5. Turn gauge wheel or crank several times to fill
seed cups with seed. Turn wheel until seed falls to
the ground from each cup.
6. Place empty container under the three seed tubes
to gather seed as it is metered.
7. Rotate gauge wheel or calibration crank until one
acre has been tallied. (see table at right)
8. Check that the three seed cups have plenty of
seed coming into them.
9. Weigh metered seed. Subtract initial weight of
container (tare weight). Divide by three. Multiply by
the number of openers on your drill to determine
total pounds seeded per acre. If this figure is differ-
ent than desired, set your small seeds seed cup
lever accordingly.
10. You may want to repeat the calibration procedure if
your results vary greatly from seed rate chart.
Many factors affect seeding rates: seed treatment,
weight of seed, size of seed, surface condition of seed,
tire configuration, tire pressure and tire slippage. Minor
adjustments may be needed to compensate for these
factors.

untreated seed of average size and test weight.
For seed not listed on the charts, compare
weight and size to those listed and use a similar
setting.
