Air Box Residue Clean-Out
Planting in extremely dusty conditions, particularly dusty
and humid conditions, or otherwise sticky soils, can lead
to air residue build-up inside the airbox. This residue can
cause seed delivery blockages.
Refer to Figure 120 and Figure 121 (Figure 120
depicts a partially and a completely plugged agitation
port, and build-up in the RH plenum chamber)
Whenever opening the airbox clean-out door , inspect
the agitation ports . If any are partially or completely
blocked, follow the clean-out instructions on this page.
Seasonally, remove the inspection ports on each of the
airbox, and inspect plenum chambers 1 (LH) and
16 (RH). If any build-up is observed, follow the more
comprehensive inspection steps and clean-out
instructions on this page.
1. Spot the planter at a suitable location for clean-out
and follow the parking instructions (page 58).
2. If seed is loaded, close the slide gate for the hopper
or bulk seed box (page 98).
3. Set out a tarp for recovery of any expected seed still
in the airbox. Open the airbox clean-out door .
4. Remove the inspection port covers from each end of
the airbox (not shown in figures).
5. Use an indelible marker to identify the hoses on seed
hose ports 1 through 16. Disconnect the clamps
and hoses.
 Further disassembly of the airbox is not
recommended, as joints are sealed with silicone
adhesive, and would need to be cleaned and
resealed.
6. Inspect the agitation ports . Break up any build-up.
Use a hooked tool or wire to pull smaller fragments
down through the ports. For larger fragments, reach
in through the inspection ports or vacuum them out
via those ports.
7. Inspect the entire plenum area for build-up. Break
up any deposits. Vacuum them out through the
inspection ports.
8. From the seed hose ports , inspect the seed air
ports . Break up any deposits. Vacuum out from
clean-out door.
9. With all ports and doors still open, operate the
planter fan to blow up any remaining loose residues.
10. Reconnect the seed hoses. Reinstall the inspection
port doors. Close the clean-out door.
