Seed Rate Speed Change
The seed rate speed change is designed to give you two
speeds for different types of seeds and rates. The two
drive types are high range (fast speed) and low range
(slow speed). To change the drive type and chain pitch
changes, refer to Figure 3-1. Remove 5/8” nut, 5/8” lock
washer and 5/8” flat washer. Flip speed change sprocket
for desired drive type.

Seeding Adjustments
1. Using the seed rate charts, beginning on page 12,
determine the seeding rate for the seed you will be
planting and make the following adjustments.
a. Decide whether you need the slow or fast drive
type. Change the speed change sprocket if
necessary, to the desired drive type, see Figure 3-
1 on page 9.
b. Locate the seed rate adjustment handle at the
rear of the seeder and move it to the indicator
number obtained from the charts, see page 10
Figure 3-2. For best results, first move adjustment
handle all the way to the left. Then move the
handle to the desired setting, moving from a lower
to a higher number.
2. There are many factors which will affect seeding rates:
seed treatment, weight of seed, surface condition of
seed or roller slippage. Minor adjustments may be
needed to compensate for these factors.
3. The seed rate charts are based on average size seed.
This may differ from the seed you are using. Use the
seed rate charts as a guide. For lighter than average
seed, the setting should be increased. For heavier
than average seed, the setting should be decreased.
4. Complete the following procedure to calibrate the rate
for your specific seed.
a. Place several pounds of seed over three of the
seed cups at the outboard end of the seeder.
b. Raise the seeder off the ground and support
safely, leaving rear roller to rotate freely.
Rotate the rear roller to see that the drive system
is working properly and the feed cups are free
from foreign matter.
c. Place a drop cloth under the seeder to gather the
seed as it is metered.
d. Rotate the drive roller assembly. For 72” seeder:
62 rotations to get 1,000 sq. feet, or 680 rotations
to get 1/4 acre. For 48”seeder: 88 rotations to get
1,000 square feet or 960 rotations to get 1/4 acre.
Be sure to check the three feeder cups to make
sure each cup has plenty of seed coming into it.
e. Weigh the seed which has been metered. Divide
by three. This will give you the ounces/pounds
metered by each feeder cup. Convert to pounds
and multiply by the number of cups on your
seeder to arrive at the total pounds per 1000
square feet your seeder would meter at that
setting. If this figure is different than desired, set
your feed cup adjustment lever accordingly.
5. You may wantto repeat the calibration procedure if the
results of your calibration vary greatly from the
suggested settings on the chart.
NOTE: Turn the rear roller clockwise for proper
feeder cup rotation.
