Materials Clean-Out
Main Box Clean-Out
Refer to Figure 30, which depicts the seed cup door handle
in a normal operating position
.
1. Set the Seed Rate Handle to zero (0). This moves
the seed cup sprockets out of the seed path.
2. Position a tarp or bucket under each row or set of
rows to be cleaned out.
3. At the seed cup for that row, pull the door handle
out of the operating detent range, and swing it down
to position
.
4. Open the main seed box and use a small brush to
sweep seed toward seed cups set to clean-out. If
seed does not flow freely, inspect seed cup, hose
and seed tubes for obstructions.
5. Wash out the seed box with high pressure water.
It is not necessary to operate the seed meter drive shaft
for clean-out. With the Seed Rate set to zero, nothing
moves inside the seed cups; however, an inspection of
the flutes for excess wear and damage does require
shaft rotation.
Set the Seed Rate Handle to 100. Raise and lock-up the
drill. Turn the seed meter jackshaft with the calibration
crank, while another person inspects the flutes from the
open seed boxes.
Native Grass Box Clean-Out
If a suitable vacuum is available, open the Native Grass
box lid, and vacuum out remaining seed.
If too much seed remains for the vacuum, or no vacuum
is available:
1. Raise and lock up the drill. Place a tarp under the
Native Grass seed tubes.
2. Set the Native Grass (right gearbox) Drive Type to 4.
Optionally install the smallest final Driven sprocket.
3. Install the calibration crank, and turn the drive sys-
tem until no seed flows from Native Grass tubes.
4. Vacuum out any residual material from above.
Water wash-out is not recommended for the Native Grass box,
particularly if seed lubricants have been used. Water may
cause build-up of solidified residue. Filler material used in
native grass mixes can also present problems.
