If the planter has Y-tubes, shut off the gates at all of
the Y-tubes.
9.
Turn on the air fan and let it run. Use the
“SPLIT AIR -” softkey
a
to reduce the regulated air
pressure to a low value, 1in water or less - this
diverts most of the air to the bulk seed delivery
system.
Reduce fan speed as necessary to obtain a low
meter pressurization.
Clean out meters with fan running. Work from one side of
the planter to the other.
Meter Clean-Out
When planting is completed, it is commonly the case that
some seed remains. There may be seed in the hoppers,
hose lines, and meters.
Refer to Figure 127
The planter includes an 817-811C container
for meter
clean-out, stored in a spring-loaded holder at the right
rear of the air manifold. The container can hold all the
seed in the meter and inlet (up to a closed slide gate).
The container can be converted into a true funnel for
complete system clean-out.
Note: The hoppers are connected to the rows with
clamped hose, and are not intended to be routinely
unlatched and tipped for clean-out.
Funnel Conversion
Materials and tools needed:
•
a length of 1
1
⁄
2
inch I.D. hose
•
a worm drive clamp with a working diameter of
approximately 1
1
⁄
2
to 2
1
⁄
4
inch
• a hacksaw
b
with fine-toothed blade
Trim the sump
from the funnel. Slide the hose
fully
onto the funnel tip. Secure with clamp
(do not
-over-tighten clamp, the funnel wall be crushed).
The choice of complete system clean-out process
depends on whether you are using the 817-811C as a
container or funnel.
a. The “FILL METER” function can divert all the air to seed delivery, but only does so for a short period of time (~90 seconds).
b. The funnel wall is thin ABS. Scissor-type pipe-cutting tools may fracture it. Rotary-type pipe cutting tools may slip off.
