Problem Clean-Outs
For normal unloading of residual materials at completion
of planting, see “Unloading Materials” on page 65. For
normal clean-out of residue, see “Material Clean-Outs”
on page 108.
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. The hopper is not designed to hold
water at full capacity. Add no more water, remove meter
box instead, and clean out from below.
