Section 3: Adjustments
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 25) with seed in the
box unless complete clean out is desired.

Calibrate Main Seedbox Seed Rate
See page 36 for instructions on how to calibrate the
Small Seeds Seedbox.
IMPORTANT: Seed rates provided in the charts may
be inconsistent with actual planting rates due to
seed size, weight, treatment, moisture content,
surface condition, ratio of inert material to seed,
different seed mixtures, humidity, tire size, tire
pressure, tire configuration, tire or rear roller
slippage, and ground preparation. Minor
adjustments 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 1-3 to
calibrate seed rate.
1. Use main seedbox seed rate charts beginning on
page 26 to determine seed rate and drive range:
a. Decide which drive range is required (low or high
range). If necessary, change speed change
sprocket to accommodate correct speed range.
See "Speed Change Sprocket" on page 22.
b. Refer to Figure 3-8 on page 25: 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 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.
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.
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. Make sure the three seed cups have plenty of
seed falling into them.
