Brush Meter Maintenance
Agricultural Chemical Hazard:
Follow material supplier recommendations carefully. Handle
the meter as if it were treated seed. use supplier-recommended
cleaning agents. Any seed treatment build-up inside a meter is
likely to be at a higher concentration than on the actual seed.
Refer to Figure 93 and Figure 94
1.
During planting days, remove, clean and inspect
seed plates
daily. See “Installing Brush Meter
Plates” on page 19, and “Seed Plate Maintenance”
on page 80.
2. Inspect wear strip . Replace if worn through, or
worn to less than 0.25 mm (0.010 inch) thick, at any
spot.
Equipment Damage Risk:
Operate only with an intact wear strip. If the strip is missing,
or worn at any spots, the meter housing will be damaged by
continued operation.
3. Inspect for worn, deformed, clogged, matted or
missing brushes
. Inspect brush retainers for
cracks.
If you are experiencing irregular seeding rates (doubles
in particular), removing and cleaning the brushes may
restore correct operation.
Over time, brushes wear down, and deform in the
direction of plate rotation. Brushes generally need to be
replaced annually.
4. If treatment build-up is a problem, use talc, or more
talc, in the next planting.
When replacing the upper brush, make sure the brush
base is flush with the meter housing. Re-tighten the three
screws in this order:
Meter Storage
Remove seed plates for meter storage.
If meters are stored installed in the planter, plug seed
tubes to prevent pest entry. If meters are removed for
storage, secure them in a pest-proof location.
