Material Clean-Out
When planting is completed, it is commonly the case that
some fertilizer and seed remains. There may be seed in
the hoppers, hose lines, and meters.
The clean-out procedures are different for the fertilizer
and seeding systems.
Seeding System Clean-Out
Refer to the 401-406M or 401-571M Operator manual.
Seeding system clean-out is the same as for the
standard YP24 or YP40 planter, with two minor
differences:
• The seed hopper is smaller and cannot be entered for
problem clean-outs.
• There are no Y-tubes in the seed delivery system.
Figure 19 shows the location of the seed airbox
clean-out door handles.
Fertilizer System Clean-Out
1. When planting is completed, raise the planter, but
leave the fan running for 30 seconds to empty the
base of the meter, delivery hoses, and applicators.
2. Unless a tarp will be used to collect the remaining
fertilizer, move the planter to an area with a flat clear
surface. Comply with fertilizer supplier instructions
for suitable areas at which to cover fertilizer.
3. Install transport locks on the raised planter. Shut off
the tractor. Mount a collection tarp if only a small
amount of fertilizer remains.
Refer to Figure 20
4. Open the calibration door (rear door). If the air
system is empty, no material may fall.
5. Open the clean-out door (forward door). Expect
material to flow in significant volume until the hopper
is empty.
6. Turn the ground drive wheel several revolutions to
empty the meter flutes.
If a second person is available, open the hopper lid
and inspect the meter flutes while turning the wheel.
7. Recover the fertilizer.
8. With the clean-out and calibration doors open,
power-wash the fertilizer hopper from above. Rotate
the ground drive to expose all meter flutes to the
water. Wipe doors, seals and meter flanges.
9. Use a wire to tie the doors partly open during drying
and storage. This allows condensation to drain while
preventing pest entry. See page 12 for lid operations
prior to storage.

Possible Dust and Chemical Residue and Fume Hazards:
Wear a respirator, and any other protective equipment
specified by the seed supplier and/or seed treatment supplier.
Expect chemical residue, dust and fumes during clean-out.
Equipment Damage Risk:
Do not leave fertilizer in the hopper for extended periods.
Fertilizer is generally corrosive, and will attack expose metal
surfaces.
