Small Seeds Adjustments
Refer to Figure 3-10:
Use seed rate charts on Page 27 to determine seeding
rate for the seed you will be planting.
1.
See Important Note above. Move seed rate
adjustment lever to cup setting number obtained
from the seed rate charts. For best results, first move
adjustment lever all the way to the left and then to the
desired setting.
•
Increase setting if seed is lighter than average.
•
Decrease setting if seed is heavier than average.
2.
Complete the following procedure to calibrate
dispersal rate for your specific seed.
a. Place several pounds of seed over three of the
seed cups at the outboard end of the All Purpose
Seeder. Do not allow any of the seed to reach
other cups.
b. Pull seed tubes out of these three drops.
c. Raise and support rear roller off the ground using
a jack.
d. Rotate rear roller to make sure drive system is
working properly and that the feed cups are free
from foreign matter.
e. Place a container under the three seed tubes to
gather seed as it is metered.
f. Rotate rear roller the number of rotations noted in
the table below. Be sure to check the three feed
cups to make sure each cup has plenty of seed
coming into it.
g. Weigh the seed which has been metered out and
divide that weight by three to get the number of
pounds metered by each seed cup. If your weight
is in ounces, divide the weight by 48 to get the
number of pounds metered by each seed cup.
h. Next, multiply number of pounds per cup by
number of cups on your seeder to arrive at total
pounds per 1000 sq. ft. or pounds per 1/10 acre.

NOTE: Seeding rates will vary greatly with variations
in seed size, seed treatment, weight of seed, soil
surface condition, and rear roller slippage. Minor
adjustments to the seed rate adjustment lever may
be needed. We recommend that you test and adjust
your All Purpose Seeder using the procedures listed
below to help insure an accurate seeding rate.
i. If calculations are based on 1/10 acre, multiply
total pounds by 10 to arrive at total pounds per
acre. If this figure (total pounds) is different than
desired, then readjust your seed cup adjustment
lever accordingly.
3.
You may want to repeat calibration procedure if
results of your calibration vary greatly from
suggested settings in the chart.

IMPORTANT: Remember, field conditions will affect
seeding rates. When seeding, check amount of seed
you are using by noting acres or square feet seeded,
amount of seed added to the seeder, and level of
seed in the seed box.
If you have accurately calibrated the seeder for your
seed and you suspect that you are seeding more or
less seed than desired, you may need to adjust the
seed rate adjustment lever slightly more/less to
compensate.
IMPORTANT: Never operate small seeds box
with seed rate adjustment lever set at 0. Always
remove retaining pin (#1) shown in Figure 3-3 on
page 15 to stop seed cups from turning. Allowing
any of the seed cups to turn with the adjustment
lever set at 0 will damage the cups.
DO NOT operate seeder with seed rate adjustment lever set
on 0.
