Cleaning Air Control
Increased row speed usually requires
increased cleaning air. There is a condition
which may occur if the cleaning air control is
too low and there is not enough air to
effectively fluff the load of vine material and
peanuts on the disc separator. This lack of air
hinders proper separation and causes good
peanuts to ride out of the back of the machine
in the hay. This condition may mimic a
condition of too much cleaning air and
peanuts being blown out over the tail board,
but subsequent reductions in cleaning air will
not improve the condition. This indicates an
original problem of too little cleaning air,
rather than too much. Experimentation in the
field is important to find a cleaning air control
setting which minimizes the loss of good
peanuts and provides a clean sample in the
bin.
Starting Position: The cleaning air control
should be set initially in the ¾ open position.
Adjustments: Opening the cleaning air control
will reduce the amount of light trash (sticks,
shriveled peanuts, etc.) in the bin by floating
the material out over the tail of the separator.
If the cleaning air is too high, good peanuts
will be blown out
of the tail of the machine.
We suggest opening the cleaning air control
until a few of the good peanuts can be seen
being blown out over the tailboard. Then
decrease the cleaning air control in ¼“
increments until no more good peanuts are
being blown out over the tailboard.
Do NOT make this adjus
machine running!
If 10% speed reduction is used, it
may be necessary to increase cleaning air
control position to compensate for
decreased fan speed.
Do NOT make this adjustment with the
machine running!
