Cannot get a valid solution from Best Fit Drain.
Symptom Problem Solution
Best Fit Drain does not return a
valid solution for a drain design. Minimum and Maximum slope are not
set low and high enough respectively,
in other words the range is not wide
enough.
The ditch track may have been
recorded from low elevation to high
elevation, and best fit drain is looking
for a solution to make water run uphill.
Set Minimum and Maximum slope to
lowest and highest allowable levels to
widen the range of cut depths. Re­run
best fit drain.
If ditch track was recorded from low
elevation to high elevation best fit
drain is attempting to find a solution to
make water run uphill. Record ditch
from the highest elevation to lowest
elevation.
Drain Map shows and upward swale(vertical) at end
of drain track.
Symptom Problem Solution
Recorded drain design has a
vertical rise or uplift at the end of
the ditch track. Ditch track stop point was recorded
while receiver was not at the lowest
point of elevation on the ditch track. When ending at ditch track at a point
where the water drains, ensure that
the implement receiver is stopped and
recording is finalized with the receiver
at the lowest point of the ditch track.
In other words, if the ditch track is
recorded traveling downhill finalize
recording BEFORE proceeding up
any incline from the ditch drain.
Vertical guidance appears after Machine starts to
AutoTrac. Implement is still active after AutoTrac
shuts off at the end of a track.
Symptom Problem Solution
Vertical guidance bar does not
shows correction at same time or
position that AutoTrac is engaged.
While implement is still active or
engaged AutoTrac guidance is lost.
AutoTrac is engaged and AutoTrac
guidance is present before the
implement height guidance is
available. Ditch track was recorded in one
direction and Ditch was cut in the
opposite direction. AutoTrac guidance
is based on location of the Machine
receiver and Implement height
Guidance is based on the location of
the Implement Receiver. If track was
recorded driving one direction and cut
in the opposite, the distance between
the receivers is the distance driven
without guidance from either AutoTrac
or Implement height depending on
direction of travel in relation to the
direction of the recorded pass. Cut the ditch track in the same
direction that the track was recorded
in.
If it is not feasible or practical to
record and cut or pull in the same
direction, machine begins to AutoTrac
before implement requires ground
engagement, and Autotrac guidance
is lost before the end of the track or
before the implement height guidance
ends.
Ditch track was recorded using
machine receiver as source.
Implement height guidance is active
when the implement receiver is over
the track recorded by the machine
receiver. Machine begins to AutoTrac
before implement requires ground
engagement, and Autotrac guidance
is lost before the end of the track or
before the implement height guidance
ends.
Guidance does not show track right away.
