PF3000 Troubleshooting
Ag Leader Technology Harvest Mode
April 2002 6-3
Problem Cause Solution
Bu/Ac or lbs/AcYield too
high or low (cont.). The top shaft of the
grain elevator was
adjusted during
harvest to tighten the
elevator chain. Adjusting the top shaft of the grain elevator
changes how the grain hits the flow sensor, and
calibration becomes inaccurate. You must change
to a different grain type and recalibrate the weight.
IMPORTANT: Use the lower elevator adjuster
to tighten the elevator chain, instead of
adjusting the top shaft. Make sure the top shaft
is adjusted so there is ½ in. or less clearance
between the tip of the paddle and the top of the
elevator housing.
The dry lbs/bu setting
is incorrect, causing
bushels to be
calculated incorrectly. Press MENU, SETUP, and GRAIN. Select the
grain type being harvested using the up/down
arrow KEYS. Press EDIT SETTINGS. You can
change the dry lbs/bu on every grain type except
CORN (56lbs/bu), SOYBEANS (60lbs/bu), and
WHEAT (60lbs/bu). For the other grain types,
select the Dry lbs/bu row and then press the EDIT
key. Change the value by using the up/down
arrows. After the correct dry lbs/bu value is set,
bushels and bushels per acre are corrected on all
the loads set on that grain type.
NOTE: Set the dry lbs/bu only once. If you think
the bushels are incorrect, troubleshoot the grain-
weight calibration.
