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 87 and Figure 88 (Figure 87 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 37).

2. If seed is loaded, close the slide gate for the hopper

or bulk seed box.

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.

Note: 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.
