Seed Cup Settings
Refer to Figure 3-7:
Each seed cup is equipped with a four-position gate. The
highest gate handle position shown is for small seeds,
the second and third positions are for larger seeds. The
forth position (Handle rotated fully down below the
bottom tab) sets the gate at wide open to allow complete
clean-out of seed cup.
Seed rate charts are based on the gate handle being set
in the highest position. Typically, most seeds will use the
highest gate handle position. If using larger seed and it is
not discharging properly, you can try using the other two
gate handle positions.

IMPORTANT: Most applications for this seeder
require the gate handle be placed in the highest
position.
MAKE SURE all gate handles are in the same
position before seeding.
Do Not set gate handles in the fourth position and
seed rate adjustment lever to the widest open
position (See Figure 3-8 on page 21) with seed in the
box unless complete clean out is desired.

Calibrating & Adjusting Seeding Rate
1.
Use seed rate charts beginning on page 22 to
determine correct seeding rate and adjustments:
a. On the right hand side is the drive system. Decide
if the drive needs to be set-up for low range or
high range. If necessary, change speed change
sprocket to accommodate correct speed range.
See “Speed Change Sprocket” on page 18.
b. Refer to Figure 3-8 on page 21: Locate seed rate
adjustment lever at the rear of the seeder and
move it to the indicator number obtained from the
charts. For best results, first move adjustment
lever all the way to the left and then to the desired
setting, moving from a lower to a higher number.
•
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 seeder. Do
not allow any of the seed to reach other cups.
b. Pull the seed tubes out of these three drops.
c. Support drive unit off the ground as follows:
•
Gauge wheel drive units: Raise and support
drive tire (right tire) off the ground using a jack.
•
Rear roller drive units: Raise and support rear
roller off the ground using a jack.
d. Rotate tire or 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 gauge wheel or rear roller the number of
rotations noted in the table to the right. Be sure to
check the three feed cups to make sure each cup
has plenty of seed coming into it.
IMPORTANT: Seed rates provided in the charts
may be inconsistent with actual planting rates due to
seed size, weight, treatment, moisture content, ratio
of inert material to seed, different seed mixtures,
humidity, tire size, tire pressure and ground
preparation. Minor adjustments to the cup setting
may be needed to compensate.
NOTE: To determine seed rates for seeds not listed
in the charts, compare weight and size to those
listed and use a similar setting. Follow steps 1 and 3
to calibrate seed rate.
NOTE: Rotate tire/rear roller by grasping the
tire/roller at the bottom and pulling away from the
front of the seeder and pushing toward the front of
the seeder at the top of the tire/rear roller.
