The container/funnel may be attached to the housing of
the seed meter, freeing your hands for other tasks during
clean-out. Normal use of the funnel is:
10. Close the seed inlet shutter on the meter (page 76).
This minimizes the seed volume at disc removal.
11. Remove the rain cover (page 76). The funnel cannot
be snapped in place with the cover installed.
12. 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.
13. Rotate the funnel forward until the slot at lip center
engages a tab on the bottom center of the meter
housing.
14. Remove the seed disc (page 79).
15. Slowly open the seed shutter (page 76) to empty the
seed up to the wing tube.
16. If the air system is running, there may be more seed
than the funnel can hold (as a container). Use the
shutter to turn seed flow off, and empty funnel.
Refer to Figure 115
17. Clean seed from all brushes (shop vac
recommended).
18. Inspect brushes (page 98).
19. Rotate funnel clockwise, remove and empty.
20. For imminent operations:
Install next seed wheel for operations. Set inlet
shutter for next seed (page 76).
21. For storage:
Close seed inlet shutter. Leave disc out.
22. Re-install rain cover (page 76).
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 includes 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.
