Dry Fertilizer Clean-Out
For normal unloading of residual fertilizer at completion
of application, see “Fertilizer Unloading” on page 105.
The present section covers completely cleaning out
hopper and air system, when residues need to be
minimized.
1. Perform normal material unloading (page 105), then
fold the planter in preparation for a move to a site
suitable for wash-out.
2. Reposition planter to a suitable site with rinse water
and hose available. This may be two different sites if
each hopper contained a different material.
If no otherwise suitable location is available, perform
a fertilizer or treated seed clean-out on an up-hill
portion of the field last treated.
3. Remove strainer (page 41). 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-Out” on
page 107).
4. Install the calibration crank (see Seed Rate
Manual). Open both calibration and clean-out doors
on the meter.
5. Power wash the interior of the hopper while a second
person cranks the meter.
6. Re-install strainer. Close lid tight and secure handle.
7. After cleaning out the last hopper, close all doors.
Run air system for 10 minutes to blow moisture out
of meter and lines.
8. Open hopper meter doors. Run air for 5 minutes.
9. Leave meter doors open. Run air for 5 minutes.
10. Shut off air. Clean door seals and meter box faces.
11. Close meter doors. Move planter to parking or
storage site.
12. Follow normal Parking instructions (page 63) or
Storage instructions (page 64).
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 3) 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 planter must be left unattended
at any time prior to step 6.
