Meter Brush Maintenance

Possible Chemical Hazard:
Wear a respirator for brush cleaning. Brushes will have talc
and graphite residue, and may have residues of hazardous
seed treatments.

Refer to Figure 84
A HEPA

a

vacuum cleaner is recommended for brush

cleaning. Washing brushes is not recommended and
may cause matting. Do not scrape them with sharp
instruments.

The first indications of excess brush or damage wear are
normally observed on the seed monitor or in air system
operation.

• If the tufted brushes

are worn/damaged, the seed

“double” rate rises, increasing population.

Finding an occasional cracked seed “hung up” on a
tuft fiber is not uncommon, and is not an indicator that
brush maintenance is required. Merely remove the
seed.

• If the strip brushes

are worn/damaged, air pressure

regulation may become unstable, or require increasing
fan speed over time.

If you find you need to exceed recommended fan rpm
ranges, the regulated air system may be taking too
much air due to meter leakage.

In severe cases, seed may leak past the strip brushes,
causing spikes in population. If you frequently observe
seed in between the strip brushes, one or both may
need replacement.

• If the seed drop brush

is worn/damaged, its

anti-static effect may fade, which can result in “skips”
due to smaller seeds failing to release, and lower
populations.

If an obvious groove is worn in the drop brush, replace
it.
