Seeding Adjustments
1. Use seed rate charts beginning on page 18 to
determine correct seeding rate. Make adjustments
as follows:
a. Decide whether your drive needs to be set-up for
low range or high range. If necessary, change the
speed change sprocket to accommodate the
correct speed range. See “Speed Change
Sprocket” on page 16.
Refer to Figure 3-6:
b. Locate seed rate adjustment lever at rear of
seeder and move it to indicator number obtained
from the seed rate charts. For best results, first
move adjustment lever all the way to the left. Then
move lever to desired setting, moving from a lower
to a higher number.
• Increase seed rate setting if the seed is lighter
than average.
• Decrease seed rate 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 seeder. Do
not allow any of the seed to reach other cups.
b. Lower seeder frame onto blocks supporting rear
roller just above ground level to allow roller to turn
freely.
c. Rotate rear roller to make sure drive system is
working properly and seed cups are free from
foreign matter.
d. Place a drop cloth under the seeder to collect all
seeds that are metered out.
e. Be sure to check the three seed cups to make sure
each cup has plenty of seed falling into it and no
other cups are receiving seed.
f. Rotate rear roller as noted in table below.

Rear Roller Rotations to Cover
1000 Sq. Ft. 1/10 ACRE
APS1548 103 rotations 450 rotations
APS1560 89 rotations 388 rotations
APS1572 73 rotations 319 rotations
APS1586 61 rotations 266 rotations
IMPORTANT: Use seed rate charts as a guide.
There are many factors which will affect seeding
rates: seed treatment, weight of seed, soil surface
condition and rear roller slippage. Minor
adjustments to the seed rate handle may be needed
to compensate for these factors.
NOTE: Rotate rear roller by grasping the roller and
pulling away from the seeder at the bottom of the
roller and pushing toward the seeder at the top.
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.
i. If calculations are based on 1/10 acre, multiply
total pounds by 10 to arrive at total pounds per
acre.
j. 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 on the chart.

NOTE: To determine seed rates for seeds not listed
on the charts, compare weight and size to those listed
in the seed rate charts and use a similar setting.
Follow steps 4 and 5 to calibrate seed rate.
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 seeder, and level of seed
in the seed box. You may need to adjust the seeding
rate slightly to compensate for field conditions if you
suspect that you are seeding more or less seed than
desired; and you have accurately calibrated the
seeder for your seed.
IMPORTANT: This seeder is equipped with a four-
position door on each seed cup. The highest handle
position is for small seeds, the second and third
positions are for larger seeds. Grass seed
applications usually require the highest position.
MAKE SURE all handles are in the same position
before seeding. The wide open position (lowest
position) will allow complete clean out of seed cup.

DO NOT open cups to the widest position with seed
in the box unless complete clean out is desired.
