9. Trac Speed
Dictates when AUTO TRAC™ adjusts Ground
Balance.
Trac Speed allows adjustment of the amount of
ground mineral change required to cause
Autotracking to occur. At slower speeds (lower
numbers) it takes a significant change in the
ground to cause tracking to occur. At faster speeds
(higher numbers) it takes very little change in the
ground mineral to cause tracking to occur. The end
result, more tracking occurs at higher numbers than
at lower numbers. Too much tracking can cause
errors in the ground balance setting. Not enough
tracking can result in the ground balance setting
never catching up with changing ground. TRAC
VIEW is used to see how much tracking is occur-
ring. Generally, a faster (higher number) TRAC
SPEED is needed for more consistent ground
conditions. Slower TRAC SPEEDS (lower num-
bers) is needed for more inconsistent ground
conditions. "TRACK" appearing every three to five
sweeps of the loop is the ideal setting when the
ground conditions will allow.

Tips - It is desirable to
select a TRAC SPEED that
tracks the ground once
every three to five sweeps
of the loop however, this
may not be possible in
extremely consistent, or
extremely inconsistent
ground conditions, which
may TRAC less or more
than this desired standard.
