Seed Box Rate Adjustment
• To prevent damage to seed meters, do not
apply excessive force to adjusting nuts.
Failure to do so may result in the seed being
pinched between the cut-off and washer
inside the seed cup.
• Do not close the meters more than 1/8" when
there is seed in the meters without rotating
the seed shaft to prevent damage to the
rotating washers and retainer rings in the
seed meters.
• Do not attempt to open the meters more than
1". (Feed rolls could become disengaged
from washer in the seed cup.)
NOTE
To avoid Seed Meter damage, if there is seed in the
Meters, decrease rate in small increments. Decrease rate
no more than one nut revolution and rotate Seed Shaft to
purge seed from Meters. Continue adjustment as
needed.
NOTE
Before filling with seed be sure Seed Shaft turns freely
and Seed Meters are free of any foreign matter.
Wrenches for adjustment are stored on a Pin at the back
of the Transmission. See Figure 3-10.

IMPORTANT
The Clutch must be disengaged when Seed Shafts
are turned manually for Calibration.
Seed Rate Chart is located inside the Seed Box Cover
and in this manual. See Figures 3-13 and 3-14. It should
be used as a general guide only.

WARNING
Because of seed variation, a more accurate rate can be
determined by turning the 11/16 Hex Seed Shaft on the
Transmission to Calibrate the Seeder. See "Calibration
for Unlisted Seeds" on Page 3-12.
On the right side, the Seed Rate for the Seed Meters can
be set by adjusting the Seed Rate Adjusting Nut and
Adjusting Screw. See Figures 3-11 and 3-12.
IMPORTANT
DO NOT Loosen or Adjust the 1/2-13 Locknut. See
Figures 3-11 and 3-12.

1. To increase the rate of seeding: loosen the 1-8 Nut
on inside of the Bearing and turn the outer Seed Rate
Adjusting Nut to the desired higher number setting,
then tighten the 1-8 Nut using supplied wrenches.
2. To decrease the rate of seeding: loosen the Seed
Rate Adjusting Nut and set it to the new desired
position; then tighten the 1-8 Nut using supplied
wrenches.
Seed Meters discharge to the front of the machine to aid
the operator in determining proper operation. In addition,
reflective amber decals are placed on the seed shafts to
indicate rotation.
