Meter Disk Installation

1.

Cross-check Seed Rate Chart data against part
number/description molded into disks to be used.

Population Risk:
Use the same disk in all active rows.

2.

Inspect disks to be installed. Do not install damaged
or excessively worn disks. Either can cause irregular
seeding. Chips and cracks accelerate brush wear.

3.

Remove meter rain cover (page 68).

Refer to Figure 91 (depicting an empty meter)
4.

Inspect meter (see page 94 for details).

5.

Make sure clamp

is aligned with seat

.

Refer to Figure 92
6.

With the seed pocket side facing the meter housing,
place the new seed disk on the disk seat.

7.

Rotate disk clamp

clockwise 45deg to clamp disk.

Clamp seats into detents

in disk hub.

Note: On a new meter, or with new brushes installed,

force the disk into the brushes to allow the disk
clamp to rotate. This condition eases as the brush
fibers are trained during initial rotations.

Note: With slightly used brushes, when a disk is first

clamped, it is normal for the disk hub to be flat with
the face of the disk seat only on the inlet (rear) side.
The disk fully seats as it first turns. This condition
eases as the brush fibers receive further use.

Brush Mis-Seating Risk:
Rotate disks forward shortly after disk installation. If planting
is not anticipated within an hour or two of disk installation,
rotate the drive system a few turns to ensure that meter brushes
lean in the correct direction. Correct lean improves meter
performance and reduces air consumption. This step is
particularly important for new brushes.

Brush seating may be accomplished with or without seed
present, and may be combined with “FILL DISK”. See
step 9 on page 51.

8.

Reset seed inlet shutter

to setting recommended

by Seed Rate Chart, or to your own developed value.

9.

On the seed monitor console, select the new
Material, seed disk Cell Count, and target
population.

10. Re-install rain cover (page 68).
