Problem Clean-Out
For normal unloading of residual materials at completion
of planting, see “Fertilizer Unloading” on page 76. For
normal clean-out of residue, see “Fertilizer Clean-Out”
on page 77.
If, however, parking and storage recommendations have
not been followed, it is possible to have hard-to-remove
material present.
If the material fails to pass through the clean-out door,
take the following steps to remove it. Do not consider
entering the hopper until first completing these tasks.
Open the clean-out door.
Remove the strainer and evaluate the problem.
For example:
• If the problem is a single moveable large object, such
as a dead animal, fishing out from above may be the
solution.
• If the problem is congealed materials, scoop out a
sample from above and see if the mass dissolves in
water. If so, and there is a small amount of the material
involved, rinsing, or rinsing and pumping the hopper
from above may be the solution.
For small amounts of residual materials, poking with a
long pole may suffice to push it through the clean-out.
If poking doesn’t produce satisfactory results, and you
intend to try wash-out, at least poke one hole down to the
meter clean-out, so that water can flow out.
If wash-out is contemplated, start by introducing a small
amount of water, and make sure that it appears at the
clean-out within 15 minutes. If not, you will just be adding
water to the problem. Add no more water, remove meter
box instead, and clean out from below.
Removing Meter Box
Removing the meter box exposes 18
×18 cm (7×7 inch)
holes through which stubborn material may be extracted.
Refer to Figure 79
1.
Not shown: Loosen the gearbox-to-meter chain idler
and remove the chain. Disconnect inlet and outlet
hoses. Disconnect or remove the seed rate sensor.
2. Loosen all the nuts securing the meter box to
the adaptor . Unscrew the nuts to the bolt ends,
but do not completely remove the nuts.
3. The meter box has a bead of silicone sealant
between it and the adaptor. Use a pry tool to free the
meter box from the bottom plate.
4. Once hanging entirely on the loose bolts, remove the
nuts and lower the meter box from the hopper.
When re-mounting the meter box, scrape off the old
silicone sealant and replace it with fresh sealant.

Machine Damage Risk:
Do not fill the hopper with water. The hopper is not designed
to hold water at full capacity.
