3. Leave the tractor hitched and in park with the
parking brake set. If the tractor cannot be left
hitched, block the drill tires.
4. Deploy the ladder.
5. Remove and clean the strainer. While the strainer
is removed, inspect the hopper for signs of
problems that may prevent normal clean-out,
such as objects or congealed masses too large
to exit through the meter.
6. Open clean-out doors on the meter of the hopper
to be cleaned out.
7. Power wash the interior of the hopper.
8. Install the strainer. Do not leave the strainer out
after wash-out. Close the lid tight and secure the
handle.
9. After cleaning out the last hopper, close all doors.
Run the air system for 10 minutes to blow
moisture out of the meters and lines.
10. Open all meter doors. Run air for 5 minutes.
11. Shut off the air. Clean the meter door seals and
meter box faces.
12. Close meter doors as for parking or storage.
13. Move the drill to a parking or storage area.
Problem Clean - Out
If parking and storage recommendations have not
been followed or material is defective, it is possible to
have hard-to-remove material present.
If the material fails to pass through the meter doors,
remove the hopper strainer and evaluate the
problem. You may need to force the material out with
either a long pole or wash-out.

If the problem is a single movable 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 material involved, rinsing, or rinsing
and pumping the hopper from above is the best
solution.
For small amounts of residual materials, prodding
with a long pole may push it through the clean-out
doors.
If poking does not produce results, and you intend to
try wash-out, poke at least one hole down to the
meter clean-out so that water can flow out. Start with
a small amount of water, and make sure that it
appears at the clean-out within 15 minutes. If not, do
not add any more water. The hopper is not designed
to hold water at full capacity.

Hopper Entry for Maintenance
Rapid Suffocation Hazard
Encrusted grain may be loose and flowing
beneath the crust. Any hollow spaces are
highly likely to have insufficient oxygen
and/or toxic gases from microbial action.
Falling through a crust can result in death in
seconds. Never enter a hopper to dislodge
a crust or bridge.
Hopper entry may be necessary in some unusual
circumstances, such as:
 hopper level or pressure sensor replacement, or
 removal of an obstruction that cannot be pulled
out with the meter box removed and cannot be
fished out or pumped out from above.
Only enter a hopper with at least one trained and
equipped attendant present. Do not enter a hopper
for routine maintenance, unloading, or cleaning.
Should a situation arise where hopper entry is
necessary, take the following precautions:
Evaluate the hazards - All persons involved should
review the materials safety data sheets (MSDS) for
any treatments and/or fertilizers used in the hopper
since it was last thoroughly cleaned, and the most
recent materials even if the hopper was cleaned.
Retain the MSDS information for any medical
treatment that might be required.
Dislodge crusting or bridging
- From outside the
hopper, break up any hard surface on top of the
material, or forming layers within the material.
Empty the hopper - See “ Unloading Hopper
Materials
” on page 74. If a blockage makes this
impossible, use an external pump line to remove as
much material as possible without performing a
hopper entry. Pump until at least some material is
exiting the clean-out door. Leave the clean-out door
open.
Clean the hopper
- From outside at the walkboard,
power-wash the inside of the hopper. Use a mild
detergent sprayer. Rinse thoroughly. Allow the
hopper to air with the lid and clean-out door open
until moisture has evaporated.
