Seed Meter Setup and Adjustments
The only seed meter adjustments are for the seed
inlet gate, a choice of disks, and meter pressure.
Seed Meter Rain Cover
The rain cover keeps side winds from pushing seed
out of the disk cells. It also keeps precipitation,
sunlight, and field debris out of the meters. It acts to
direct any dust or debris coming from the seed
downward toward the soil. A knockout brush on the
inside of the cover brushes loose seeds off the seed disk.
To remove the rain cover:
1. Unclasp the latches (1 and 2).
2. Pivot the cover forward and down at the tab (3)
and remove.
When removing a cover, inspect it for damage and
missing parts. If a cover does not have both latches it
can be lost during transport or field operations. Also,
inspect the knockout brush for wear.
To replace a latch, slide the replacement latch onto
the cover lugs from the meter side, then snap the
other end down over the lugs.
To replace the knockout brush, see “
Knockout
Brush Replacement ” on page 63.
Seed Disk Installation
Population Risk
Make sure to use the same disk in all active
rows.
1. Check the part number and description on the
seed meter disks against the seed rate chart
data.
2. Before installing, inspect the disks. Do not install
damaged or worn disks which can cause
irregular seeding. Chips and cracks can increase
brush wear.
3. Remove the meter rain cover.
4. Inspect the meter and brushes (see page 61 for
details).
5. Make sure the seed meter clamp (1) is aligned
with the disk seat (2).
6. With the seed cells side facing the meter
housing, place the new seed disk on the disk
seat.
7. Rotate the seed meter clamp (1) clockwise 45° to
clamp the disk. The clamp will seat into the seed
disk hub (2).
With a new meter or new brushes, force the disk
into the brushes to position the seed meter
clamp. The brushes will be trained during initial
rotations.
With slightly used brushes, when a disk is first
clamped, the disk hub may be flat with the disk
seat only on the gate side. The disk should seat
as it first turns. This condition will ease as the
brushes are used.
8. Rotate disks forward a few turns after disk
installation to make sure the meter brushes lean
in the correct direction. This is particularly
important for new brushes. It will improve meter
performance and reduce air consumption.
9. Set the seed inlet gate to the setting on the seed
rate chart.
10. On the console, select the new Material, seed
disk Cell Count, and target population.
