8. If the air system is running (with Y-tube open),
there may be more seed than the container can
hold. Use the seed inlet gate to turn off seed flow
to empty the container.
9. Clean seed from all brushes. A shop vacuum is
recommended to clean the brushes.
10. Inspect the brushes.
11. Rotate the container/funnel clockwise to remove
and empty.
12. If the planter will be used again.
a. Install the next seed disk or blank disk for the
operation.
b. Set the inlet gate for the seed.
13. If the planter will be stored:
a. Close the seed inlet gate.
b. Do not put a seed disk back in the meter.
c. Reinstall the rain cover.
Alternate Meter Clean-Out
Use a shop vacuum cleaner with a narrow hose
nozzle to clean out a meter.
1. Close the seed inlet gate.
2. Release the disk clamp while holding the seed
disk against the meter.
3. Tip the top of the disk away from the meter.
4. Insert the shop vacuum hose nozzle and remove
the seed.
5. Open the gate to allow seeds in the inlet and the
drop hose to flow to the shop vacuum hose
nozzle.
Seed Tube Clean-Out
The seed sensor in the seed tube can have a buildup
of dust, dirt, and seed treatment which can cause
false low population alarms.
If the seed meter is empty, remove the seed disk and
insert seed tube brush (part number 891-259C) into
the seed tube from above. With the planter raised,
you can insert the brush from below, whether the
meter is empty or not.

Seed Meter Brushes Maintenance
Possible Chemical Hazard
Brushes will have talc and graphite residue,
and may have residue of hazardous seed
treatments. Wear a respirator for brush
cleaning.
A HEPA vacuum cleaner is recommended for brush
cleaning. Washing brushes is not recommended and
may cause matting. Do not scrape the brushes with
sharp instruments.
The first indications of excess brush wear or damage
are normally observed on the seed monitor or in air
system operation.
 If the tufted brushes (1) are worn or damaged, the
seed doubles 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.
Remove the seed and continue with operations.

If the strip brushes (2) are worn or damaged, air
pressure regulation may become unstable or required
increasing fan speed over time.
If recommended fan rpm ranges need to be
exceeded, 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 seed is
frequently seen between the strip brushes, one
or both may need replacement.
 If the seed drop brush (3) is worn or damaged, its anti-
static effect may fade, which can result in skips due to
smaller seeds failing to release, and lower population.
