Material Clean-Outs
For normal unloading of residual materials at completion
of planting, see “Unloading Materials” on page 113.
The present section covers completely cleaning out
hopper and air system, when residue needs to be
minimized.
1. Perform normal material unloading (page 113), then
fold and lock the drill (page 37) in preparation for a
move to a site suitable for wash-out.
2. Reposition drill to a suitable site with rinse water and
hose available. This may be two different sites if
each hopper contained different materials.
If no otherwise suitable location is available, perform
a fertilizer or treated seed clean-out on an up-hill
portion of the field last planted or treated.
3. Leave the tractor hitched, in Park with parking brake
set. If tractor cannot be left hitched, block drill tires
with chocks.
4. Deploy a ladder (page 46). Remove strainer
(page 48). Clean strainer. While strainer is removed,
inspect hopper for signs of problems that may
prevent normal clean-out, such as objects or
congealed masses too large to exit through meter
(see “Problem Clean-Outs” on page 115).
5. Install the calibration crank. Open both calibration
and clean-out doors on the meter of the hopper to be
cleaned out.
6. Power wash the interior of the hopper while a second
person cranks the meters (page 56).
7. Re-install strainer. Close lid tight and secure handle.
8. After cleaning out the last hopper, close all doors.
Run air system for 10 minutes to blow moisture out
of meters and lines.
9. Open all hopper meter doors. Run air for 5 minutes.
10. Shut off air. Clean door seals and meter box faces.
11. Close meter doors as for parking or storage. Move
drill to parking or storage site.
12. Follow normal Parking (page 66) or Storage
(page 67) instructions.
Review Regulations and Policies:
The steps at left apply when there are no specific clean-up
requirements provided by national, regional or local
regulation, nor by the seed and/or fertilizer supplier. Review
any legal requirements, instructions on the material
containers, and any Material Safety Data Sheets. Give priority
to regulations and supplier instructions. Modify the
instructions here as needed to comply.
Confined Space Hazard:
Do not enter hopper. Do not remove strainer (step 4) until
ready to clean strainer and wash-out hopper. Do not leave
strainer out after wash-out. Return the strainer to the hopper
and secure the hopper lid if the drill must be left unattended at
any time prior to step 7.
