Performance 9980 Self-Propelled Peanut Combine
Increased ground
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
hin
ders 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 fan
damper
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 in
order to find a cleaning fan damper setting
which minimizes the loss of good peanuts and
provides a clean sample in the bin.
Starting Position: The cleaning fan damper
should be set initially in the ¾ open position.
Adjustments
: Opening the cleaning fan
damper 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 fan damper in ¼“
increments until no more good peanuts are
being blown out over the tailboard.
NOTE! If 10% speed reduction is used, it
may be necessary to increase the cleaning
fan damper position to compensate for the
decreased fan speed.
