Seed Rate Adjustment - Landoll SSB-8 Operator's Manual

OPERATION

Seed Rate Adjustment

NOTE
Wrenches for adjustment are stored on a pin at the back
of the transmission. See Figure 3-8.
Figure 3-8: Adjustment Wrenches
Seed cups discharge to the front of the machine to aid
the tractor driver in determining proper operation. In
addition, reflective amber decals are placed on the seed
shaft to indicate rotation.

• 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.)

WARNING
Seed rate charts specific to seeder size are located
inside the seed box cover and in this manual. (See
"Table for 8 Foot Seedbox" on page 3-9.) (See "Table
for 10 Foot Seedbox" on page 3-10.) (See "Table for
12 Foot Seedbox" on page 3-11.) It should be used as
a general guide only. Based upon your seeder size. See
Calibration ("Calibration 8 Foot Seedbox" on
page 3-9.) ("Calibration 10 Foot Seedbox" on
page 3-10.) or ("Calibration 12 Foot Seedbox" on
page 3-11.) Because of seed variation, a more accurate
rate can be determined by turning the 15/16" Hex nut on
the transmission to calibrate the seeder.
Seed rate for the front or meter box is set by adjusting the
micro-meter on the right side. See Figure 3-9.
1. To increase the rate of seeding, loosen the large
locknut on inside of the bearing and turn the seed
rate adjusting nut to the desired setting, then tighten
the large locknut.
2. To decrease the rate of seeding, loosen the seed rate
adjusting nut and set it to the new desired position;
then tighten the large locknut.
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.
