Dry Fertilizer Clean-Out
Possible Agricultural Chemical Hazard:
Wear all protective equipment specified for use with the most
recent types of dry fertilizer used in the hoppers. Clean-out
operations are likely to result in airborne dust, which could be
contaminated with hazardous chemicals.
For small amounts of residual fertilizer:
1.
Raise the planter.
2.
If any seed remains in the seed hoppers, clean them
out first, or disconnect the seed meter Range or
Transmission chain.
3.
Place a tarp, or multiple collection containers, under
the applicator tubes.
4.
Operate the ground drive wheel (top forward) until
the hoppers are empty.
5.
For extended storage, use a hose and clean water to
wash out the hoppers, meters, hoses and applicator
tubes.
For large amounts of remaining fertilizer, or any amount
that is not flowing properly through the meters, use this
alternate procedure:
1.
Raise the planter.
2.
Place a tarp, or large collection containers, under the
front of the planter.
Equipment Damage Risks:
Fully uncouple and empty one, and only one hopper at a time.
Attempting to empty multiple hoppers with shafts still coupled
is likely to result in machine damage. If two or more hoppers
are uncoupled at the same time, the interconnecting drive shaft
is completely free and may fall.
Refer to Figure 110
3.
At each end of the hopper, remove the pin
at the
shaft coupler
. Slide coupler onto adjacent shaft.
Refer to Figure 111
4.
At the rear of each hopper, remove two cotter
and
two cradle pins
.
Refer to Figure 112
5.
Open the hopper lid (see page 32).
6.
With one person at each end of the hopper, carefully
tilt it forward to empty it.
7.
Operate the hopper drive shaft to clear the meter.
8.
Tilt the hopper upright. Secure at rear with pins.
9.
Rotate drive shaft to align hole with coupler pins.
Slide couplers into engagement. Re-install pins.

Heavy Material Flow Hazard:
Use two or more people for hopper tilt clean-out. Do not stand
directly in front of the hopper being unloaded. Wear protective
equipment, including dust masks or other respiratory support.
Full hoppers are heavy, may tip rapidly, and may be hard to
control. They may empty suddenly.
