5.11.1 Material Clean-
Outs
For normal unloading of residual materials
at completion of planting, see “Unloading
Materials” on page 77.
The present section covers completely
cleaning out hopper and air system, when
residue needs to be minimized.
Perform normal material unloading, then
fold and lock the drill in preparation for a
move to a site suitable for wash-out.
Reposition drill to a suitable site with air
hose available.
Leave the tractor hitched, in Park with
parking brake set. If tractor cannot be left
hitched, block drill tyres with chocks.
After cleaning out the hopper, close all
doors. Run air system for 10 minutes to
blow moisture out of meters and lines.
Open the hopper meter door. Run air for 5
minutes. Close meter doors as for parking
or storage. Move drill to parking or storage
site.
Follow normal Parking or Storage
instructions.
If, however, 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
clean-out door, take the following steps
to remove it. Do not consider entering the
hopper until first completing these tasks.
1. Open the hopper cover.
2. 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.
3. For small amounts of residual materials,
poking with a long pole / brush may
suffice to push it through the clean-out.
4. If poking doesn’t produce satisfactory
results it may be necessary to use
compressed air.
5.11.2 Hopper Entry
Normal use of the hopper and routine
maintenance do not require entry.
Hopper entry may be necessary in some
unusual circumstances, such as removal of
obstructions too difficult to pull out with the
meter box removed and not susceptible to
fishing or pumping out from the open cover.
Should such a situation arise, observe the
following precautions:
Review the Material 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
subsequently cleaned. Retain the MSDS
information for any medical treatment that
might be required.
Designate or engage a team for hopper
maintenance. Hopper entry is never
a single-person activity. At least one
attendant/observer is necessary. Give
priority to individuals already trained in
confined space operations. Designate a
leader (who will not be the entrant) with
authority to terminate the activity.
