Seed Box Rate Adjustment
WARNING
•
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.

TABLE OF CONTENTS
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 3-1 and 3-2. It should
be used as a general guide only.
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 3-13.
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.
