Materials Clean-Out
Main Box and Dual Box Clean-Out
Refer to Figure 37, 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. If a vacuum cleaner is available, use it to remove
residual material.
It is not necessary to operate the 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 and disengage the
lock-out hub. With openers lowered to engage the clutch,
the seed meter jackshaft can be slowly turned 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
system until no seed flows from Native Grass tubes.
4. Vacuum out any residual material from above.
Equipment Damage Risk:
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.
