Seed Rate Adjustment
WARNING
• To prevent damage to the seed meters, do not
apply excessive force to the 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. This prevents damage to the
rotating washers and retainer rings in the seed
meters.
• Do not attempt to open 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 and the Calibration Crank
Assembly are stored in the toolbox. See Figure 3-9.

IMPORTANT
The clutch must be disengaged (power off) when
seed shafts are turned manually for calibration.
The seed rate chart is located inside the seed box cover
and in this manual. See Figure 3-11. It should be used
as a general guide only. Because of seed variation, a
more accurate rate can be determined by turning the 3/4"
Hex Nut on the transmission to calibrate the seeder. See
"Calibration for Unlisted Seeds" on page 3-9.
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 Figure 3-10.
IMPORTANT
DO NOT Loosen or Adjust the Hex Nuts with Set
Screws.
