Small Seed Meter Assembly/Adjustment - Landoll 5531 Operator's Manual

OPERATION AND MAINTENANCE
Small Seed Meter
Assembly/Adjustment
1. If the small seed meter shaft assembly is
disassembled for maintenance or repair, the seed
meters and seed rate adjustment will need to be
reset or zeroed to set the meters equally across the
seed box.
2. To reset the seed meters, remove all seed, chaff, and
dirt from the seed box and seed meters.
Reassemble the meters and drive shaft assembly,
but leave the locking set collars, meter feed rolls and
meter cut-offs loose on the shaft. Leave the drive
chain disconnected as well.
a. Set the seed rate adjusting nut to "0A", and
tighten the large locking nut against the right side
of the seed shaft bearing. The two smaller 1/2"
locking nuts should be tight against the threaded
adjusting screw as well.
b. For each seed meter, slide the meter feed roll
and cut-off to the right to fully close each meter.
Slide the locking collar on the left side of each
meter against the meter cut-off and tighten the
lock collar.
c. For each seed meter, slide the right locking set
collar next to the meter feed roll (leaving
.010"-.020") of clearance and tighten the set
collar. Make sure the flutes on the meter feed roll
are lined-up and inserted in the meter housing.
d. Rotate the square seed shaft by hand to verify
the shaft is not binding and rotates freely.
e. Loosen the large locking nut against the seed
shaft bearing. Adjust the seed shaft in and out to
make sure all meter feed rolls are properly
aligned and not binding. Do not force the
adjustment or damage will occur to the meter
assembly.
f. Reconnect the drive chain.
g. Set the seed rate adjustment to the desired rate
and tighten the locking nut.
3. The seed meters should now be reset to zero, and
match the zero indication on the adjusting screw.
