Meter Clean-Out
Refer to Figure 108
The 817-811C seed collection accessory (funnel
) may
be attached to the housing of the seed meter, freeing
your hands for other tasks during clean-out.
Note: The funnel does not fit rows to the left of gauge
wheels on twin-row planters. Use vacuum or tarp
collection on those rows.
Note: It may be necessary to raise a twin-row planter to
obtain clearance for the funnel. Use transport locks
(page 23) if the planter is raised.
1. Close the seed inlet shutter on the meter (page 74).
This minimizes the seed volume at disk removal.
2. Remove the rain cover (page 74). The funnel cannot
be snapped in place with the cover installed.
3. Align the left (rear) end of the funnel lip with the
top of the lower (rear) cover latch ear. Place the right
(front) end of the funnel lip
between the meter
housing and the seed tube.
4. Rotate the funnel forward until the slot at lip center
engages a tab on the bottom center of the meter
housing.
5. Remove the seed (page 77).
6. Slowly open the seed shutter (page 74) to empty the
seed up to the slide gate.
7. If seed remains in the hopper, use the slide gate to
control the volume of flow.
Refer to Figure 107
8.
Clean seed from all brushes (shop vac
recommended).
9. Inspect brushes (page 101).
10. Rotate funnel clockwise, remove and empty.
11. For imminent operations:
Install next seed wheel or blank disk (page 78) for
operations. Set inlet shutter for next seed (page 74).
12. For storage:
Close seed inlet shutter. Leave disk out.
Close Y-tube (if any).
13. Re-install rain cover (page 74).
At end-of-season clean-out, inspect a few seed meter air
release screens. If they require cleaning, consider
cleaning all rows.
Seed Tube Clean-Out
The seed sensor in the seed tube can be obscured by
build-up of dust, dirt and seed treatments. This can
cause false low population alarms. The planter incudes a seed tube brush (Great Plains part
number 891-259C). If the seed meter is empty, remove
the seed disc and insert the brush into the seed tube
from above. With the planter raised, you can also insert
the brush from below, whether the meter is empty or not.

Alternate Meter Clean-Out
To use a shop vacuum cleaner, with narrow hose nozzle,
to clean out a meter:
• Close the seed shutter.
• Release the meter clamp, hold the disk against the
meter.
• Tip the top of the disk away from the meter.
• Insert hose nozzle and remove seed.
• Open shutter to allow seeds in inlet and drop hose to
flow to vac nozzle.
