Material Clean-Out
When planting is completed, it is commonly the case that
some seed remains. There may be seed in the hopper or
bulk box, seed in the airbox, a small amount of seed in
the hose lines, and seed in the meters. Some meters
may be filled up to the air release vent (which prevents
additional seed from reaching that meter).
A complete system clean-out is a 3 step process.
1. Empty airbox (and hopper, if desired).
2. Blow residual seed to meters.
3. Clean out meters with fan running.
Possible Dust and Chemical Fume Hazard:
Wear a respirator, and any other protective equipment speci-
fied by the seed and/or seed treatment supplier. Expect dust
and fumes during hopper clean-out.
Hopper Clean-Out
Perform hopper clean-out with the fan off.
Refer to Figure 110
1.
Close the slide gate at the base of the hopper.
2. Place a tarp under the seed cart.
Refer to Figure 111
3.
Open the clean-out door on the bottom of the airbox.
Seed in the airbox immediately falls onto the tarp.
Note: If needed, additional access doors are provided.
4. Open the slide gate slowly. The remaining seed in
the hopper falls onto the tarp. Use the slide gate to
regulate the flow and, as needed, stop it while
recovering seed from the tarp.
5. Rapidly open and close the slide gate to dislodge
seed in the tracks. Tap on the sides of the hopper to
dislodge residual seed.
6. Close slide gate.
Close clean-out door.
7. Perform an air system clean-out to remove final
amounts of residual seed from airbox, and all seed in
meters.
Entrapment and Rapid Suffocation Hazard:
Never enter a hopper for any reason.
Keep strainer in place at all times.
▲ A hopper that is full or merely appears full can be an
entrapment hazard. You can sink entirely into the grain, or
into an oxygen-deficient void, and suffocate in a matter of
seconds. Grain bridges and crusts are especially danger-
ous.
▲ When hazardous fumes are present, you can be quickly
overcome even with the hopper lid open.
▲ Do not enter a hopper for material loading, material
unloading, hopper cleaning or meter maintenance.
▲ Clean hopper by power washing from outside hopper top.
