Material Clean-Outs
For normal unloading of residual materials at completion
of planting, see “Unloading Materials” on page 65.
The present section covers completely cleaning out hop-
per and air system, when residues need to be minimized.
1. Perform normal material unloading (page 65), then
fold the drill in preparation for a move to a site suit-
able for wash-out. If cleaning out both hoppers, plan
to clean out the rear hopper first.
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 por-
tion of the field last treated.
3. Leave the tractor hitched, in Park with parking brake
set. If tractor cannot be left hitched, block drill tires or
set optional parking brakes. Leave the drill folded for
transport in either case, as the openers must be
raised for cranking, and access to the meters is eas-
ier when folded.
4. Lower ladder (page 44). Remove strainer (page 46).
Clean strainer. While strainer is removed, inspect
hopper for signs of problems that may prevent nor-
mal clean-out, such as objects or congealed masses
too large to exit through meter (see “Problem Clean-
Outs” on page 109).
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 57).
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 both front hopper meter doors. Run air for 5
minutes.
10. Leave front meter doors open. Open rear hopper
meter doors. Run air for 5 minutes.
11. Shut off air. Clean door seals and meter box faces.
12. Close meter doors. Move drill to parking or storage
site.
13. Follow normal Parking (page 69) or Storage
(page 70) instructions.
Review Regulations and Policies:
The steps at left apply when there are no specific clean-up
requirements provided by national, regional or local regula-
tion, 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 regula-
tions 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.
